What is the suffix for china?

There isn't a single, universally accepted suffix for "China" in the same way that you might have a suffix for a country like "France" (e.g., "French").

However, depending on the context, you can use different words or phrases to denote something related to China:

* Chinese: This is the most common adjective used to describe something from or relating to China.

* Sino-: This prefix is used to indicate something relating to China, often in academic or historical contexts. For example, "Sino-Japanese relations."

* 中华 (Zhōnghuá): This is the traditional Chinese term for China, and it's sometimes used in place of "China" in certain contexts.

The best way to choose the right term depends on the specific situation and what you're trying to convey.
