Baohe Palace is the essence of the Han palace architecture, belonging to a temple-style building in the Forbidden City of Beijing. Ming Yongle was built in 18 years (1420), and several times burned and rebuilt. The existing main beam is still a Ming Dynasty building. The temple was named in the beginning of the Ming Dynasty. Ming Jiajing was renamed the Jianji Temple in 41 years (1562), and the temple was named Baohe Temple in the second year of Qing Shunzhi (1645).
