The Erwang Temple is one of the core scenic spots of Dujiangyan at the foot of Yulei Mountain. It was originally built in the Southern and Northern Dynasties, but was later destroyed. The existing buildings were built in the late Qing Dynasty and the early Republic of China. Originally to commemorate Dujiangyan's excavator Li Bing and his son Erlang, there are also angels such as Wenquxing. After all, Qingchengshan-Dujiangyan scenic spot is dominated by Taoism. I heard a tour guide telling a Japanese person that Wenquxing is "Mr. Yu" (good teacher). It feels a bit funny, but to some extent it is not wrong.
