Many people will go to the Yunlai Observation Deck, but they don't know that they have passed a village called Mountain Village. If you chat with the people in the village carefully, you will find that the young children in this village will speak Mandarin. Although it is a bit bad, it is OK. In fact, most of the ancestors in this village are from Yunnan, China, and their current descendants can relearn Chinese by relying on a school inside, the name of this school is called Haiyu Middle School, which is built by friends in Taiwan. The style of the campus is also particularly Taiwanese.
