How change user`s language

I build up a metabase using docker this morning
at the beginning , metabase auto use “Chinese” language during the installation.
but there are couple “Chinese” language , like simplified Chinese (China) , traditional chinese (Taiwan/HK)
metabase use only simplified Chinese which I don’t want to.

after the installation , I through I can change language in user settings , but the language option show

The default language for this Metabase instance.This only applies to emails, Pulses, etc. Users' browsers will specify the language used in the user interface.

so , is that means users can not change their preferred UI languages ?
