According to the literature, the Northern Song Dynasty was a period of Buddhist revival, seeking dharma westward and then reaching its climax. At that time, Indian monks came to China with Buddhist relics. In the fifth year of the Northern Song Dynasty, a monk from Uttar Pradesh, a northern Indian state, took care of him and enshrined the Buddhist parietal relic in Chang Gan Temple in Jinling (now Hongzhi). He spent four years in the underground palace of Asoka Tower in Chang Gan Temple. In the second year of Tianxi, Chang Gan Temple celebrated another day. In the Southern Song Dynasty, it was recorded in Jiankangzhi of Ding Jing that Tianxi Temple was a long-term Dojo, where Sakyamuni relics were buried, and there was a true stupa named "Shengjue stupa" in Xiangfu.
