I re-translated the simplified Chinese document (zh-cn) by myself. The following are the reasons why I did this:

• When I used thexlsx package in my project, I encountered that exporting xlsx files could not add styles (it is said to be only available in the pro version). I found exceljs as an alternative and it was very easy to use.
• I found a Chinese document (add cn doc #834 ) while viewing the document, but after reading it, I found it very disappointing, and the traces of machine translation are also obvious.

Therefore, I plan to re-translate to avoid misleading others. I am not a professional translator, but the documents will be corrected manually sentence by sentence. Due to the limitations of my personal level, errors inevitably occur. However, I can guarantee that most of them are correct.

The body part of the document has been completely translated, and the "Release History" part has not been completely translated yet. I will take the time to improve later.
