This is my first post on this forum. If you find any errors or areas for improvement, please let me know!
After accessing https://www.arrl.org/tqsl-download and downloading and installing TQSL, the language displayed was Japanese.And changing the language bar also had no effect.

- InVisit DAEinApplication, foundTQSL

- Right-click to selectTQSLand select Open the package contents.

- Once you've entered the package contents, click on the folder Content/ - in sequence.> Resources/ I can find many language packs.

- Since the downloaded file is in Japanese, we need to replace the contents of the `ja.lproj` folder with the contents from a folder using Chinese (either `zh_CH.lproj` or `zh_TW.lproj`).


- After replacing it, open tqsl again and you will see the Chinese interface.
