🇨🇳 Mandarin Speaker?

Every topic includes Mandarin Traps — callouts that explain exactly why Mandarin habits lead you astray, and how to fix it.

  1. Pick your level — or just dive into whatever topic is bugging you right now.

  2. Read the fun version first — every topic starts with a TL;DR and a visual explanation. No textbook tone.

  3. Check the Mandarin Traps — see why your 中文 instincts are working against you, with real examples in both languages.

  4. Go deeper if you want — every page has a deep dive section for edge cases, exceptions, and the “why does English do this?” questions.

  5. Use the memory tricks — each topic ends with a hook to make the rule stick. Because memorizing grammar tables is nobody’s idea of a good time.


This site is built for intermediate ESL learners — especially Mandarin speakers — who know enough English to communicate but want to stop making the same grammar mistakes.

You won’t find baby-level “this is a cat” content here. You also won’t find a 200-page textbook. Just the rules that actually matter, explained like a friend would explain them: with humor, visuals, and zero judgment.

English is weird. Let’s figure it out together.
