while I generally agree that the guide can be simplified, [Export](#lowering-bit-rate) the audio file takes the reader to the section about bit rate lowering, and while it covers the export process, I would say it's confusing -- you need to either make a small section dedicated to the export procedure, or keep duplicated steps as below in the mp3directcut part of the article

(also, what does your "Sync changes with the English article" checkbox mean -- is there still something you wanted to backport from Chinese to English and forgot?)

The Chinese translation reflects the original content before this PR.
This step will be completed once I have the English article cleaned up.

Uh I seem not to explain it clearly, so I changed it.

some issues encountered when setting mp3DirectCut up:

• It complains ACM not found, even after I installed this library
• For LAME library, I'm unsure about which bitrate to use (Constant, Variable, Average) and which is used by our RC
• It only runs on Windows (requires x86 libraries) and Android, and hasn't been updated since 2022/01
• If we have the need to change the bitrate, we need either of the two libraries mentioned above

It seems kinda unfriendly for regular mappers. Maybe there is a better approach to edit MP3 files, but I'll try to update the current ones first.

this has been going on for quite a while, so let's try and finally get it in. please make sure the Chinese translation you added follows the updated version of the guide, and I'll merge it

Now the ZH translation is up to date. Ready to go 🚀
