Choose a series
Three kids series build the reading ladder — pinyin → first characters → character families — plus a beginner course for parents and teens who want to learn alongside.
Kids · Starter🐻Pinyin for Kids
The gateway to reading Chinese: a 10-lesson animated pinyin adventure. Kids learn the vowels, consonants and four tones with the Pinyin Kingdom bear — one focused classroom session at a time.
Kids · Level 1🌱First Characters
A first step into Chinese characters for ages 3–7. Each lesson bundles short story animations that teach 2–3 everyday characters — sun, rain, family and numbers — followed by a picture-friendly quiz.
Kids · Level 2🔥Character Families
Level up with Mi Xiaoquan's animated character families: discover how the fire, water, wood and metal radicals build whole families of characters — the superpower behind reading hundreds of new words.
Adults & Teens💬Chinese for Beginners
A structured HSK 1 video course from absolute zero to your first real conversation: greetings, names, countries, numbers and age — with a vocabulary list and quiz after every lesson.

Frequently asked questions
Are the courses really free?+
Yes. All series, video classes and quizzes are free, with no account or signup required. Progress is saved automatically in your browser.
What is “immersive classroom mode”?+
In the kids series, the class plays like a real lesson: the video cannot be fast-forwarded (rewinding is allowed), and the quiz runs on a timer. This keeps young learners focused and makes sure the material is actually watched.
Which series should my child start with?+
Start with Pinyin for Kids — it teaches the sound system every reader needs. Then move to First Characters (ages 3–7) and Character Families for radical-based reading.
Why are later lessons locked?+
Each lesson builds on the previous one, so the next lesson unlocks when your child scores 80% or more on the current quiz. Quizzes can be retaken as many times as needed.
Where do the videos come from?+
Classes embed kid-friendly teaching videos from YouTube channels using YouTube's standard embed player, wrapped in our classroom controls.
Will we lose our progress?+
