Thanks for your help, Aslain and Quaksen. After diligent work, I guess I have already done improving the simplified Chinese translation, and compliing new version. I upload here and ask you for detecting any potential mistakes. If there is any mistake, please contact me for future correction. If it is ready for publish, I would focus on Chinese feedback and keep improving the translation for a certain time, as long as I have spare time.
Also I updated the readme file a bit, to inform Chinese users of Chinese feedback channel, since a lot of them don't have patience to read a lot of English.
Thanks a lot!
