How many people live there?
- You read that the city of Chongqing has about thirty million people and wonder how to say it.
- Chongqing city (Chungking)…重庆has有三千多万people人。 — "Chongqing has over thirty million people."
Count in ten thousand万 (ten thousand)
- ten thousand万 = 10,000. Chinese groups big numbers in fours: 一万 (10,000), hundred thousand十万 (100,000), 一百万 (1,000,000), 一千万 (10,000,000).
- 两万五千 = 25,000; 三十万 = 300,000.

Don't count in thousands
- 100,000 is hundred thousand十万, not one / a一百千: Chinese has no "hundred thousand" unit, so regroup by fours.
- A million is 一百万, not 一万万; 一万万 is an old word for 一亿.

1,000 × 10,000 = 10,000,000.

- Move eight places for 100 million亿: 300,000,000 → 3|0000|0000 → 三亿.
two million两百万people人。

- hundred thousand十万 = 100,000, 一百万 = a million, one billion十亿 = a billion.

You read that the city of Chongqing has about thirty million people and wonder how to say it. Close the examples. Say a Mandarin response, then write it in Chinese. Explain briefly in English what the lesson’s pattern adds. Compare with the model, then change one detail and try again.
This is supported productive practice. Compare meaning and structure; your answer need not copy the model. A partner or teacher must hear the spoken response to comment on pronunciation.
