If you see bad translations in open-source projects, please help by fixing them :)
It's a straightforward way to contribute to open-source, even if you know nothing about coding, and it helps a lot. It's hard for open source projects to find good translators.
The other thing that really helps is improving documentation. Developers hate writing docs :)
An interesting side effect is that the models coming out of China are very efficient. They don't have access to all the high-end hardware the US has, so they have to make do with what they've got.
