Describe the Bug

The region in mas formula (China Mainland) is different from that in Mac App Store (the USA).
unable to switch from China Mainland to the USA App Store
hence cannot install any application that haven't click 'get' before.

Expected Behavior

Get results from the US App Store.

Actual Behavior

Get results from Chinese App Store.

Screenshots, Terminal Output

Got results from Chinese App Store:

Cannot install due to the wrong region:

After clicking OK, it says "Error: No downloads began"

Additional Context

It has been wrong since yesterday, everything was normal before that.

I haven't switched to a Chinese App Store account before.

I've tried to restart, reinstall mas ,then restart, then reinstall homebrew, then restart.

All of those do not work.

Need help, thanks!
