Eric

The teacher is very good and very patient.

Happy

Thank you, Otto — today's 'old' and 'young' part was especially fun, and Happy had a great time! One small request: we hope you can extend as much as possible and cover no more than 7 pages per class, letting Happy express things as if she were really there. We especially love the part where you have Happy say sentences as if she's in the scene — please keep doing that, so she understands every point and expresses it correctly. Thank you, teacher, for all your hard work. See you next week! ❤️

Tian Tian

Thank you, dear Teacher Otto~ We learn so much with you every time ❣️❣️ Looking forward to the next class 🥰🥰

Beck

Witty and humorous, gentle and patient.

Tina

Thank you Otto

Angela

Thank you, teacher.

aaron

Mr. Otto. Aaron loves you very much. Your extensions and special effects make him more open. Aaron has just started speaking classes, although he is already in master classes. Your class is very good; he said you encouraged him a lot. Sometimes he can't express what he wants to say, but I believe this is only temporary — with you, he will make greater progress. If you want Aaron to improve anything after class, please leave a message for me. Thank you. P.S. It is my mistake, I didn't even notice the stars. Aaron has a twin brother named Max.

Hongzhao

Thank you, teacher.

Jerry

Great

Mandy

Thank you, teacher, for your patience and encouragement.

Daniel

The teacher's extensions are great as always! Thank you, teacher!

David

Thank you, Teacher Otto S — another information-packed class, as always.

Tina

thank you teacher

Jasmine

Thank you, teacher.

Rayen

A real treasure of a teacher. Looking forward to seeing you again.

Kimihiro

The teacher is witty, humorous and great at extensions.

Talia

Hi Otto, thank you so much, teacher — a very conscientious, responsible teacher with all kinds of magic. Today we started our first offline phonics class. We'll build up bit by bit and look forward to the day she can read on her own.

Lucky

Thank you, teacher, haha — today he picked his nose and you taught him a lesson about it. After class he felt quite embarrassed himself, haha, and promised me he won't do it again. Thank you, teacher — you're a good teacher for my child in life, too. Thank you.

Barry

I took a screenshot of your birthday video and posted it on WeChat — lots of people liked it. Your warmth and patience have made Barry love English even more. Barry studying hard is the best way to repay Teacher Otto 💪🏻

Tian Tian

Dear Teacher Otto~ Another wonderful class! 🥰 Thank you for always sharing with my child like a friend and constantly extending related knowledge! Truly amazing 😍😍 We won't be able to take the Wednesday slot for a few more months, so we're letting other friends have it for now~ Looking forward to the next class 😊😊

River

Thank you, Teacher Otto, for a wonderful class! After class River rushed out of the room saying she loves the teacher: 'Is he a magician?' 😄 We'll definitely book your classes as often as we can.

Happy

Thank you, teacher, for taking the time before class to answer the question from my last message ❤️ Today's extensions were great — next class you can keep extending and explaining in depth with her, and let her speak more. Sorry, Happy just loves you so much she got overexcited in class — hope her enthusiasm didn't bother you 😅😅. I'll review everything from your class with her afterward. See you next week! 😊

Julia

Thank you, Otto — this homework is great. After the May Day trip, having a small topic after each class is a nice way to get back into focus. I'll make sure she finishes her little home tasks. Thank you.

Lucky

Thank you, teacher.

David

Hello Otto S — after a long break, so happy to see you again.

Teddy G

Nice

Tina

good class

Angela

Thank you, teacher.

Hi Otto, thank you so much for chatting with us and sharing how to get started with phonics. We'll work hard, bit by bit, after class. Looking forward to next class.

Teddy G

Thank you.

Jerry

Great!!!

Tian Tian

Thank you for the notes, teacher~ They're very helpful! Looking forward to seeing you in our next class 😆

Lucky

Thank you, teacher — we feel your patient guidance for my child.

David

❤️❤️❤️❤️❤️

Lucky

Thank you, teacher.

Angela

Thank you, teacher.

Jeffrey

good

Talia

Hi Otto, who would have thought a seemingly simple lesson about little animals had so many learning points — different animals have different vocabulary. Learning to use it in real life — thank you. Looking forward to next class.

Lucky

Thank you, teacher.

Jerry

great

Barry

Thank you, teacher.

Julia

Thank you, teacher.

David

Learning with Teacher Otto S is pure happiness.

Thank you teacher.

Clock

Love it.

Jerry

A very good teacher.

Nina

Thank you, teacher.

Elio

Thank you, teacher.

Mandy

A wonderful class. She shared a lot with you this time, and you extended so much fun knowledge with her. Looking forward to next class.

Tian Tian

Thank you, Teacher Otto~ To be honest, on the Monday after this class, she left an important thing (her math book!) behind! So I took the chance to tell her: see, just yesterday Teacher Otto asked if you'd ever forgotten something important, you said no — and now you have! 😆😆 Thank you for always connecting English to real-life things when explaining ☺️☺️ See you tomorrow ❤️

David

❤️❤️❤️❤️❤️

Kevin

Thank you, teacher.

Tina

Thank you Otto.

Bella

good

Angela

Thank you, teacher.

Talia

Hi Otto, first, thank you so much. Talia has been a bit naughty lately, but luckily Otto is truly a teacher who knows how to grab a child's attention — always using lots of 'magic' to present the lesson, very vivid and helps my child understand better. And every time you translate things for us in simple English. A very rewarding class — we look forward to every one.

sunny

Thank you so much, teacher, for your patient answers!

Lucky

Thank you, teacher, for your hard work.

Tian Tian

Thank you, Teacher Otto 🥰🥰 for helping us learn so many new things every time 😆😆 Have a wonderful weekend~

Lucky

Thank you, teacher, for the patient teaching.

Terry1Maggie

we love Ottos

David

He did well again on the weather topic — thank you, teacher, for your patient guidance.

Kevin

Thank you, teacher.

Lucky

Thank you, teacher.

Tina

Sentences which are used in daily life are taught by Otto, and it's so nice to learn those authentic expressions.

Bella

good

Jasmine

Thank you, teacher.

Samuel

The teacher is awesome and extends so much for my child — digging into and exploring the most basic concepts together. Wonderful. We'd love to book long-term classes and hope we'll get the chance.

Talia

Hi Otto, this class we learned how to describe different kinds of weather. Talia repeated the new words after you and was so happy. Looking forward to learning more next class. Thank you.

Rosalie

Thank you!

Hongzhao

Thank you, teacher.

Jerry

A really good teacher!!!!

Barry

Thank you, teacher.

Kevin

Thank you, teacher.

Julia

Thank you, teacher.

Tina

Thank you Otto.

Bella

good

Angela

Thank you, teacher. See you next time.

Talia

Hi Teacher Otto, it's not just Talia who loves your classes — Mom does too, learning something new every class. Every one of Teacher Otto's classes is packed with substance, and you're a truly patient and fun teacher. Privately, Talia tells Dad that Teacher Otto knows lots of magic and is a fun teacher. Next class, we hope you can correct Talia's pronunciation a bit — right now only Mom can understand a lot of her English pronunciation, hahaha.

Nemo

The teacher's extensions are great.

sunny

Thank you so much, Teacher Otto — you extend so much every time, and we love this style. Next class let's continue with this unit; we'll definitely preview the text first.

Suzie

Thank you, teacher — so grateful.

Jerry

Nice!!!

Barry

Thank you, teacher 🫶🏻🫶🏻🫶🏻

Tian Tian

Thank you, Teacher Otto ❤️❤️❤️ Thank you for leaving us such valuable records 📝 every time, not only in class but in the comments too. It's really great — we can use your notes to review with my child 🥰🥰 We learn so much every class with you ☺️ Looking forward to our class this week 😁 Have a nice day 😆😆

David

An information-packed, efficient class as always. We'll be sure to review plenty afterward.

Angela

See you next time.

Talia

Hi Teacher Otto, thank you for staying a few extra minutes every class — a very rewarding lesson. Teacher Otto prepares the content so thoughtfully and extends so much extra vocabulary. Talia kept showing you her finger with a band-aid, then her shoes — she wants to share everything with you. A very patient male teacher, explaining all kinds of knowledge with super patience every class. We look forward to learning more knowledge and more spoken English with you in the coming classes. Thank you.

Olivia

Thank you, teacher!

Tian Tian

We're truly grateful that Teacher Otto does all kinds of extensions for my child every time — not only English-related, but culture and life too. Even though my child can't fully understand a lot of it at her current level, we sincerely thank you for guiding her so thoughtfully and patiently ❤️❤️❤️ Looking forward to our next class 🥰

Kevin

Thank you, teacher.

Leon

Thank you. See you Saturday.

William

Our first class with the teacher — my child loved it, said the teacher can do magic, and wants to take your class again next time.

David

Hello Teacher Otto S, every one of your classes is packed with information. I really need to print out your after-class feedback for David to review — it's so rich. Thank you! Oh, and please remind David not to play with the microphone, as it causes noise. Thank you.

Tina

Thank you, dear teacher — you've always been such a caring and responsible teacher.

Bella

Thank you.

Angela

See you next time.

Jasmine

Thank you, teacher.

Nemo

Thank you for the extensions, teacher. Our child starts primary school in the second half of the year, so I've cut back English study time and reduced foreign-teacher classes to twice a week. But I'll still keep up daily English reading and listening input.

Hongzhao

Thank you, teacher.

David

❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️❤️

Leon

Our first class — a great atmosphere, especially the super-cool way of saying goodbye at the end. Leon was amazed and delighted.

Mumu

Thank you, teacher. She's always so happy in your class.

Daniel

Thank you for your careful teaching. We'll have a good review! The class was very good, thanks for your patience!

Tian Tian

Dear Teacher Otto, we hadn't had class with you in a long time — so happy to finally see you again today~ ☺️ Thank you for expanding so, so much new vocabulary for my child, as always! Truly wonderful! Even though she can't learn it all at once, I believe reviewing will at least deepen her impression 😊 I sincerely hope she'll be able to chat with you about much more in the near future 💕 Best wishes 🌺 Have a lovely night 🥳

Bella

A really good teacher.

Angela

See you next time.

Jasmine

Thank you, teacher.

Talia

Hi Teacher Otto, Talia didn't get a nap at school today, so she was completely out of steam — but Mom learned a lot! So leaves stay green because they absorb sunlight, and leaves don't like the cold — that's why trees are bare in winter. I'll keep telling Talia about these things. Thank you, teacher. Your gestures were spot on — branches growing upward like arms, roots digging into the ground like feet. Looking forward to next class.

Nemo

Thank you, teacher. This class was wonderful again — you always find different, deeper points in the textbook. Let's keep it up next class.

Olivia

Thank you, teacher!

Lucky

Thank you, teacher.

Troye

Thank you, Teacher Otto, for a wonderful lesson — your explanation of the news was really cool. Troye was better today than the past few days, and I often remind him to let the teacher finish before sharing his own opinions. Thank you for keeping the whole class at such a good pace — I know keeping him focused throughout isn't easy. We review the sentence patterns and words you teach after every class. If there's anything you think he needs to improve or where I can help, just let me know. Wishing you all the best and good health!

Julia

Thank you, Otto. I can feel Julia's progress with complete English sentences this year — thank you for your efforts, like the structure formula you mentioned: sb. + action + where + when + why. She practices it on purpose, though maybe not enough yet — after all, we're in a Chinese-speaking environment, relying mainly on reading, cartoons, basic speaking and your class. So we hope you'll create more chances for her to interact in class, pushing her from passive to active expression. Lately she's become hugely fond of dancing, and next month she starts swimming lessons. These are her current English learning and interest plans — feel free to build on them in future to make lessons more true to life. Just letting you know. Thank you, teacher.

Jerry

Every class with Teacher Otto is so vivid and fun. Unfortunately the Sunday class clashes with Jerry's swimming lesson, so we have to give it up. We hope there'll be a suitable time to take more of your classes in future.

Mumu

Thank you, teacher.

Elio

Thank you, teacher.

Barry

Thank you, teacher — you always explain things so clearly and simply. 👍🏻

Daniel

Thank you, teacher — the extensions are easy to understand, especially great! We've moved the Sunday class to Saturday. Looking forward to next class!

Lucky

Thank you, teacher 😍

Julia

Thanks

Kevin

Thank you, teacher.

Leo

The teacher's extensions are just right: patient, step-by-step guidance, a moderate pace, pictures combined with words, and detailed explanations. A six-star treasure of a teacher!

David

Unfortunately we lost a bit of time because of device problems, but thank you so much for extending the class by almost 5 minutes for him. Schoolwork is heavy, so we've adjusted our schedule and can only see you once a week. When we can, we'll book single classes, or meet again at another suitable time. Thank you — every class is packed with substance!

Tina

Great class.

Angela

Thank you, teacher.

Jasmine

Thank you, teacher.

Talia

Hi Teacher Otto, long time no see! So happy you shared photos of your family holiday in Manila today — we saw your new look with a head full of braids, and the kids burying you in sand. It looked like so much fun; we'll try it next time too. Today we learned about fruit, and Talia loves eating all kinds of fruit, so she was very interested. Looking forward to learning lots of vocabulary with you next class.

Cathy

The teacher is very nice — in class you extend and write the sentences out for us to see. Thank you, teacher.

Mandy

I watched the replay. She was slow to warm up at the start, but once she got going, she discussed a lot with you, and you worked hard to get her talking and start the class discussion. Thank you so much. At the end, when you talked about all the kinds of dragons, she was really focused — kids love that kind of creature. Discussing like friends, she says a lot and loves to share. I saw you two share many fun things about the New Year. So much fun — looking forward to sharing more next class.

Jerry

An especially good teacher — we're lucky, and we'll keep taking classes.

Teddy

Thank you.

Kevin

Thank you, teacher.

Tina

great class

Bella

Happy New Year.

Angela

Thank you, teacher.

sunny

Thank you, teacher, for teaching my child so conscientiously every time. We really love your extensions, which help my child learn more. Thank you! I'll keep encouraging my child to follow your explanations closely.

Julia

Thank you, teacher. The clear 'what + where/when' approach is especially helpful for Julia's everyday expression. We hope for this kind of guided practice every time. Reinforce it!

Mumu

Thank you, teacher.

Elio

A really good teacher — great at drawing kids into discussion, with great extensions too. The teacher types out all the key points, which is wonderful because Elio is a visual learner. In short, thank you, teacher — we hope Elio will explore many more topics with you in future~

Barry

Thank you, Teacher Otto, for explaining words Barry might not know in English and with the help of technology — it helped Barry understand really well. Thank you 🙏🏻

Jack

Thank you, teacher.

Alaia

Thank you, Teacher Otto. It's so much fun in your class, and we learn a lot too.

Caden

Thank you, teacher.

Olivia

Thank you, teacher!

Julia

Thank you, Otto — there are so many English-English explanations every time, which really helps her vocabulary and richness of expression. Right now we're giving her lots of input. One idea: could you spend 3–5 minutes next class reviewing the words and phrases you expanded on — say with a word-chain or guessing game — to make it fun and reinforce them at the same time? We look forward to every Otto class — you're the teacher she's stayed with longest since starting foreign-teacher classes!

Joseph

Thank you, teacher.

Peng Peng

Good.

Samuel

Thank you, Teacher Otto, for the wonderful lesson. Samuel says he wishes every day could be with Teacher Otto. Thank you for the detailed guidance and the key points on the board. Thank you, teacher.

Julia

Thank you, Otto. We'll do good interactive review with Julia after class too.

Barry

Thank you, teacher.

Clock

We love this witty, humorous teacher.

Tian Tian

Thank you, Teacher Otto 💗💗 Sorry we couldn't make it home in time for class today and had to take it in the car 🥺🥺 Thank you for always connecting to real life when talking with my child. Many times she may not quite get your humor yet, but I think as her English gets better and better, she'll surely be able to chat with you more and understand your questions better 😊

Kevin

Thank you, teacher.

Angela

Thank you, teacher. See you next time.

Talia

Hi Otto — 25 minutes never feels like enough in your class. How time flies! Another class packed with substance today: who knew there were so many ways to say 'apartment'? And when you move into a new home, neighbors will come knock on the door to say hi and bring a gift. From the magic tricks at the very beginning to learning Chinese pinyin so students understand words better, Teacher Otto is truly a conscientious, meticulous teacher. Looking forward to next class.

Nemo

Thank you, teacher — another wonderful class.

Troye

The best Teacher Otto — your discussion about BYD was so fun; cars are his favorite topic. He's slow to respond, so thank you for patiently guiding him and giving him plenty of time to answer. Also, you could type a bit less — just the key points is fine. Thank you!

Mumu

Thank you, teacher.

Tina

Appreciate your help with IELTS class today. Dear Teacher Otto, can you help prepare IELTS topics to practice? She will do the test on Feb 24. Thank you for your help.

Angela

Thank you, teacher. See you next week.

sunny

Thank you so much for the extensions, teacher! Next time I'll communicate the learning progress with you in advance.

Ricky

Ricky really loves your classes and your sunny, cheerful personality. Ricky loves chatting with you, and his spoken English has improved. He even thinks of you as a friend. Ricky often watches the replays after class — things he didn't understand during class he figures out while watching, and he happily shares them with the family. Thank you for your patience; we'll book more of your classes when we can.

Samuel

Thank you, Teacher Otto. Every time we manage to book your class it's a lucky experience. Thank you for teaching Samuel so many knowledge points and experiences in class. Thank you.

Troye

Thank you, teacher! Your explanations are especially good! To borrow this lesson's theme: you are a very good teacher.

Jerry

Great!

Mumu

Thank you so much.

Barry

Thank you, Teacher Otto.

Peng Peng

Good.

Troye

Thank you, Teacher Otto — you've opened the door to a new world for us, haha. Fun classes and solid explanations. Troye says he wants to take your class every day from now on...

Maggie2Terry

Thank you very much

Jerry

Great!

Kevin

Thank you, teacher.

Mandy

Thank you for the class, teacher. Today you extended a lot and she was in great form. We hope you can bring in more discussion with her, giving her more initiative — she'll blend into class better and faster.

Peng Peng

Good.

Tina

Thank you for letting us know. Enjoy your festivals there. Have fun.

Bella

A very good teacher.

Jessie

Thank you, Teacher Otto — we can see Jessie has made big progress. Please keep having her practice speaking in complete sentences and keep correcting her grammar, so it becomes a habit.

Talia

A delightful and very rewarding class. Thank you, teacher. See you next class.

Lucky

Thank you, teacher.

David

Dear Otto S, Happy New Year! Long time no see — we miss you so much!

Barry

Thank you, Teacher Otto, for your hard work and patience with Barry. Barry is back to himself today — thank you again.

Mia

Thank you, teacher!

Lucky

Thank you, teacher.

Tina

Thank you Otto.

Lucy

Thank you, teacher, for always extending her learning — we benefit so much.

Angela

See you next time.

Jasmine

Thank you, teacher.

Talia

Hi Teacher Otto, no doubt your classes are always hugely rewarding. Today you expanded lots of vocabulary for taking different kinds of transport in more natural ways — like getting in a car versus taking the bus — and if you're really not sure whether to use 'go in' or 'take', you can use 'by'. Talia may not fully get complex prepositions yet, but Mom understood some of it. We look forward to future classes helping Talia understand better and repeat the knowledge you extend. See you next class.

Nemo

Thank you, Teacher Otto — another super class today. You explained words and sentence usage to Mooda in a simple, accessible way. You really get Mooda, and Mooda loves you too. Mooda fidgets a lot in class, but I'll help him improve that bit by bit.

Tian Tian

Happy New Year, dear teacher Otto! Thank you so much for your kind comments, they're really helpful! We are looking forward to having more classes with you 🥰🥰 Wishing you and your family a joyous New Year! May the coming year be filled with happiness, good health, and prosperity for all of you. 💗💗

sunny

We really love Otto S's classes — so cool ´_>`, just like the teacher's name. The classes are so colorful and rich. The words are getting quite uncommon now, so they take more time to understand — let's keep going together!

Jerry

This class was so much fun. Teacher Otto told Jerry all about his travel experiences — great interaction.

Clock

A fun-type teacher.

Mandy

Thank you, Otto — a wonderful class. Watching the class video I noticed you got your hair permed — even more handsome! This class she learned the new word 'similar', and I'll review it with her. Fun classes always make her lively; sometimes she goes off topic, but you pull her back quickly. She always loves sharing her things — the ice flowers she made were colored paper cut into a cup, filled with water and frozen. They looked so pretty; she made them at school and couldn't wait to share them with you. Next class we hope you'll add more discussion, and help her get familiar with and remember new words through examples and sentence-making. I'll review with her after class. See you next class.

Rita

Thank you, teacher 🌹

Peng Peng

Good.

Jerry

Great

Mumu

Thank you, teacher.

Olivia

Thank you, teacher!

Jerry

A very good teacher.

Kevin

Thank you, teacher.

Tina

Our favorite teacher, always makes class interesting and fun.

Bella

A wonderful teacher.

Angela

See you next time.

Jasmine

Thank you.

Nemo

Thank you, teacher, for your patient guidance helping him retell the text. If possible, next time you could ask more questions about the details in the pictures.

sunny

I really love Otto S's conscientious, responsible attitude in class — and you always help students expand lots of knowledge related to the text and words. We benefit so much! Thank you so much, teacher!

Bert

Thank you, teacher.

Jerry

great

Evah

Thank you — thank you for your patient guidance for Ave and the knowledge you extend.

Jerry

great

Lucky

Thank you, teacher, for all your hard work.

Mandy

Thank you, teacher, for the wonderful class. We were out, so it started a little late, but that didn't affect the lesson at all. You used exaggerated, fun ways that made it easy for my child to remember what she learned today. She already knew the meanings of these words, but you extended a lot more, and bringing in discussion gave her a sense of control, so she was very willing to speak. Looking forward to next class.

Mia

Thanks for your teaching.

Leo

We were late — so sorry, we'll be careful next time. The teacher even made up those few minutes for us — thank you so much. The teacher's feedback is thoughtful every time, summarizing the class for us. The best teacher, bar none.

Lucky

My son's favorite teacher.

Tina

thanks OTTO

Angela

See you next time.

Jasmine

Thank you.

Talia

A square can become a diamond, and it can become a rectangle — the teacher used easy-to-understand words together with gestures. Wow, a truly thoughtful teacher! Every class we learn so many authentic, different ways of saying things. And the teacher never stops mid-lesson just because time is up. A wonderful teacher. Next class we hope Teacher Otto can have Talia repeat your key points with you. Thank you.

Olivia

Thank you, teacher, for your patient guidance!

Lucky

Thank you, teacher.

David

❤️❤️❤️❤️❤️

Julia

Thank you, teacher.

Lucky

Thank you, teacher.

Leo

The teacher is sincere, the class notes are thorough, and the explanations are complete.

Tina

thank you, our best teacher

Lucy

Thank you, teacher.

Angela

We hope to always have classes with this teacher.

Jasmine

Thank you, teacher.

Clock

We really love this teacher's classes.

Rose 🌹🌹🌹

An especially good teacher.

Nemo

Mom learned the new content along with them tonight — the extensions were great! Keep it up...

Bert

Thank you, teacher.

Olivia

Thank you, teacher, for your patient guidance!

David

❤️❤️❤️❤️❤️

Julia

This is exactly the right pace — thank you, Otto. A suggestion: after each unit, do a small theme summary to consolidate the unit's content and practice retelling.

Teddy

Thank you!

Kevin

Thank you, teacher.

Peng Peng

Good.

Tian Tian

Dear Teacher Otto, so happy to have class with you~ I really wish we could have your class every week 😭😭 Thank you for using all kinds of ways to help Tiantian understand words she didn't know, and for constantly building long sentences with her. This is undoubtedly a huge help for her growth! Thank you again! Thank you 💗💗💗 Have a sweet night 😌😌

David

❤️❤️❤️❤️❤️

Tina

great

Bella

A very good teacher.

Angela

OK 👌

Jasmine

Thank you, teacher.
