Off-topic question, could those who have been there tell me, when chatting with local Taiwanese, do you often bring up political topics? Will the locals initiate a conversation about the political differences between the mainland and Taiwan after knowing that you are a Mainland tourist ?

Do you want to chat or not?

I cannot

Age and occupation play a role in how talkative people are. Older people and those in the tourism industry are more likely to be talkative, and they tend to ask about hometowns rather than getting into political topics.
