I also made a Chinese version of Open Interpreter's Demo video, can watch it on YouTube.

I will insert this video to README_ZH.md later.

Considering that the YouTube can't be visit in China, so I published the video on Bilibili. I'll remove that YouTube video photo and add two extra link to Youtube and Bilibili later.

Hi @orangeZSCB
Thanks for the PR!

We are trying to figure out a more sustainable way to manage internationalization of the README and our docs in general. They quickly go out of data and are difficult for an all-english speaking team to validate.

Do you have any ideas for alternatives to maintaining multiple READMEs? Would a GPT that translate the README be a good idea?

[orangeZSCB]

I used GPT translation to proofreading some texts to ensure the accuracy of the wording. So I think GPT translating is a good idea.
Did you guys use Google-translate before this PR?

Forget that video I made, just because I think it's too bad to use
