Why do most people speak Chinese?

It's not accurate to say that "most people speak Chinese". While Mandarin Chinese is the most spoken language in the world, the majority of the world's population does not speak it.

Here's why:

* Population concentration: While Chinese has the most native speakers, these speakers are largely concentrated in China.

* English as a global language: English is widely spoken and used for international communication, business, and education.

* Other languages: There are many other languages with large numbers of speakers, such as Hindi, Spanish, and Arabic.

The reason Mandarin Chinese has the most native speakers is due to the large population of China. However, the global language landscape is diverse, with many languages spoken around the world.
