Introduction to Li Tian's former residence: Li Tian's former residence is a simple main hall, with statues and tablets of Li Tian enshrined. According to records, in the third year of Hongwu in the Ming Dynasty (AD 1307), the people of Shangli established a shrine for the firecracker ancestor in the "Yousheng Temple" to commemorate it. On April 18 every year, there are huge crowds of people offering sacrifices, which is very spectacular.
