The six sessions 🎯
The running case is Lumen Logistics, an invented Singapore freight company, 鲁门物流 (Lǔmén Wùliú, Lumen Logistics), opening a partnership with a Shanghai distributor. You are the person they send.
Sounds and tones
How a syllable is built, pinyin and its tone marks, the four tones as shapes, why 买 (mǎi, buy) and 卖 (mài, sell) must never be confused, and the three tone changes.
🪪 Session 2 · foundationalNames, titles and business cards
Surname first, address by title, safe defaults when you do not know the title, and how a card is given and received with two hands.
🎛️ Session 3 · bench nightThe tone trainer

Counting in fours with 万 (wàn, ten thousand), prices, phone numbers, dates in Chinese order and meeting times.
💬 Session 5 · coreMeetings, calls and WeChat basics
Polite requests, booking and confirming a meeting, and WeChat as the everyday business channel.
🤝 Session 6 · capstoneThe first meeting, and the follow-up
The first five minutes scripted, the numbers said and confirmed, the WeChat follow-up sent the same day. Final scorecard.

What is honest here 🧾
Where a page rests on a standard, a paper or a guide, it says which and how it was read; where something is common practice rather than a documented rule, it says that instead.
| Claim | Status |
|---|---|
| Every count on the tone trainer bench | Really computed in your browser by a YIN pitch tracker on four synthetic voices; the bench claims the ordering of the scoring methods, not an accuracy for real speech |
| The tone values 55, 35, 214, 51 and the third-tone change | Confirmed in a published phonology paper citing Chao |
| Where the tone mark goes | Read at source in the 1958 pinyin scheme and GB/T 16159-2012; the familiar "a or e first" rule is taught as a shortcut, not as their wording |
| Card exchange and address by title | Reported from university business-Chinese guides; 王总 (Wáng zǒng, President Wang) is widely heard and not documented in them |
| HSK levels | The 2021 standard (GF0025-2021) for scope; the HSK exam's new version officially launches on 13 December 2026, so check chinesetest.cn before booking |
| Lumen Logistics and its people | Invented for the running case |
