The name of Sannian is different from that of the temple, and there is a "zi Anta" that blesses the safe birth in the temple, and the Japanese production of Pingan "produces Ning" and "three years" pronunciation is close; also said that Sannian was built in 808 AD for Datong three years, so it is called "three years". Anyway, it feels special to walk in this more than 1200-year-old street and watch these ancient features of architecture and costumes
