What are the customs and habits of Hsinchu in Taiwan Province Province? What is the Mandarin spoken by people in Taiwan Province Province?

There are many Hakkas in Hsinchu, who usually speak Hakka dialect, and some Minnan people, who account for the largest proportion of the population in Taiwan Province Province, also speak Minnan dialect at ordinary times, but everyone is familiar with Mandarin. Unless a small number of elderly people in their seventies and eighties can't speak Mandarin, mainlanders can basically communicate in the past ~!
