I don’t know if you know the book of Yuanshi Wuyu. I have seen the introduction that Japan is the same as the Red Mansion Dream. The last ten stickers of Yuanshi Wuyu happened in Yuzhi... The ticket to the museum is 500 yen, and the inside is the style of a Japanese courtyard. There are relevant short movies to watch, you can also rent Chinese explanations (payable)
