That's for sure a minus, even if you speak the language. You are restricted to a smaller subset of developers that can improve the ecosystem (and let's be frank that most good developers should know English but not Chinese, internationally speaking).

[echaozh]

The logic may not be sound as you cannot tell for sure if there are more English speaking front end developers or Chinese-only speaking ones, given the population of China.

There could roughly be as many front end developers in India ... which has 23 languages.

China also has multiple languages and dialects, see: https://en.wikipedia.org/wiki/Languages_of_China#/media/File...

English is the lingua franca of software development and I don't see that changing anytime soon.
