@Linjieyang Talking about Confucius/Daoism would be better than Buddhism, because we learn their sayings from childhood. But Buddhism... nope, we are not interested in it, especially the younger generation (myself included). I’ve never come across any Chinese people who talked with me about Buddhism or any related concepts. We find it boring. I’d say the older generation might be interested. So that’s all I have to say.
@studiousme Also I want to add, just go for it. you will have less time in the future, as in the 文言文, people always mention how you should study young. Your English is already fluent, I think learning Korean now would be better, because later, you may regret it.
