Jiayi's former residence is located in Taiping Street. Visiting the former residence requires ID card registration for admission tickets. It does not cost much. The former residence area is not large. Many buildings are built by later generations. There are some archaeological discoveries and Jiayi's biographical brief. The millennium old well is impressive. I learned Qin's theory when I read books. So when I was playing in Changsha, I came to see it specially.
