Introduction to Donghua Palace: Donghua Palace is located in front of the Zijin Peak of Bible Mountain. According to historical records, in the 22nd year of Dading in the Jin Dynasty (1182), Ma Danyang passed by here and said, "This is the scenic spot of Dongtian Blessed Land", so he rebuilt the palace on the former residence of Emperor Donghua and named it "Dongtian Blessed Land". "Hua Palace" was later renovated many times, with magnificent halls and numerous monuments. The building was destroyed in the middle of the Ming Dynasty. On the current palace site, there is only one "Stele of Emperor Donghua" written by Zhang Zhongshou in the sixth year of Emperor Qing's reign in the Yuan Dynasty (1312), with seal inscription by Zhao Mengfu. There is a cave carved on the cliff in the north of the original palace, with three regular script characters "Donghua Cave" engraved on it. It was built in the sixth year of Dade in the Yuan Dynasty (1302). In the cave, there used to be seven real white marble statues carved in white marble from the Yuan Dynasty to Zhengsan Dynasty. In 1343, the Taoist priest Geng Daoqing once built a stone pavilion above the cave with a statue of the Jade Emperor inside, hence the name Jade Emperor Pavilion. It was later abandoned.
