Here's why:
* "Chinese" is a broad term: It refers to a group of languages spoken in China and surrounding areas. Think of it like "Romance languages" (Spanish, French, Italian, etc.).
* Mandarin is the most spoken: While "Chinese" can refer to many languages, Mandarin is the official language of China and the most spoken. It's like saying "English" when you really mean "American English" or "British English."
* Other languages exist: While Mandarin is dominant, there are many other languages spoken in China, such as Cantonese, Wu, Min, and Hakka. These have significant differences in pronunciation, grammar, and vocabulary from Mandarin.
So, it's more accurate to say:
* Most Chinese people speak Mandarin.
* Many Chinese people speak other Chinese languages.
