Two things. First, TZDB is an English-language database. If you are
having trouble finding Taiwan using a traditional Chinese locale, this
is something downstream from us, either CLDR[1] or your operating
system's supplier, and you'll need to contact them to fix it.

Second, I don't observe your problem when using 'tzselect', which is the
simple English-language text-based selection interface that TZDB
distributes. See the shell transcript below. There is a separate entry
for Taiwan, which has a distinct time zone history since 1970. There is
no need for subdistricts of Taiwan, as all subdistricts have the same
such history.
$ tzselect
Please identify a location so that time zone rules can be set correctly.
Please select a continent, ocean, "coord", "TZ", "time", or "now".
1) Africa
2) Americas
3) Antarctica
4) Arctic Ocean
5) Asia
6) Atlantic Ocean
7) Australia
8) Europe
9) Indian Ocean
10) Pacific Ocean
11) coord - I want to use geographical coordinates.
12) TZ - I want to specify the timezone using a proleptic TZ string.
13) time - I know local time already.
14) now - Like "time", but configure only for timestamps from now on.

Based on the following information:
Taiwan
TZ='Asia/Taipei' will be used.
Selected time is now: Sun Aug 31 12:13:58 AM CST 2025.
Universal Time is now: Sat Aug 30 04:13:58 PM UTC 2025.
Is the above information OK?
1) Yes
2) No

You can make this change permanent for yourself by appending the line
export TZ='Asia/Taipei'
to the file '.profile' in your home directory; then log out and log in
again.
Here is that TZ value again, this time on standard output so that you
can use the ./tzselect command in shell scripts:
Asia/Taipei
