A non-trivial amount of info and discussion around Vue (esp. third-party packages) is in Chinese. Whether that's a plus or a minus depends on whether you understand the language.
I have started to use museUI. A material UI library based on vuejs. It is also mostly in Chinese. I was reluctant initially but made the jump.
Then one day I had an issue. Posted it. Interestingly some other guy posted a PR to solve that. And it got merged the next day. So it ended well for me. But can't say that for other repos. Just my experience.
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).
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.
