Introduction to Dangui Chuanfang Archway: The skeleton of the village is mainly a circular passage surrounding several large courtyards. One of the widest streets is called Archway Street. There are two stone archways on the street. The stone archways are completely imitation wood structures. One has the inscription "Qingyun Jiewu" and the other has the inscription "Dangui Chuanfang". Among the existing archways in our country, there are mainly two archways, namely the Chastity Archway and the Gongde Archway. However, the two archways in Liu's residence are the Chengxian Archway, which means "to learn from the foolish is to be virtuous". It was built by the Ming Dynasty in recognition of Liu Lu and Liu Yuchun, members of the Liu clan. It has a history of 450 years. It is currently the first of its kind in our country.
