He was granted the title of beile. He served as Minister of Internal Affairs and as a commander in Mongolia.^{[citation needed]}

In July 1873, the Qing court removed Zaicheng's title of beile, because he and Tongzhi went out of the palace to visit prostitutes in Peking. However, a month later, the original title were restored. Zaicheng didn't have a son, but because he was the next in line to adopt his father's title, he adopted Puwei to inherit it after his death. He died in June 1885 at the age of 28, and his adopted son Puwei succeeded him as Prince Gong. Because he was the eldest son of Yixin, he was given the posthumous title of "Prince Guomin of the Third Rank".^{[citation needed]}
