In Mandarin Chinese:
* 县 (xiàn) means county. It is a subdivision of a prefecture or city.
In Taiwanese Hokkien:
* 縣 (hiān) also means county.
However, the pronunciation differs slightly between Mandarin and Taiwanese Hokkien.
It is important to note that "xian" is not a word in Taiwanese Hokkien. It is the same character used in both languages, but with a different pronunciation.
If you're referring to a specific county in Taiwan, you'll need to provide its name to determine the correct pronunciation in Taiwanese Hokkien.
