Introduction to Yushifang: A memorial archway erected for the daughter of Emperor Qianlong of the Qing Dynasty. It is said that Qianlong's daughter had a black mole on her face, and the fortune teller said: "The Lord will have disasters in his life, and he must marry a lucky person to avoid disasters." The court discussed that only descendants of saints are the best. Since the Manchus and Han were not allowed to intermarry, Qianlong let his daughter He recognized Yu Minzhong, co-educator of the University and Minister of Household Affairs, as his adoptive father. He changed his surname to Yu Minzhong and later married into the Kong family. This square was erected in memory of Yu.
