Zhaoqing City Cultural Relics Protection Unit. Located in the old city of Zhaoqing, at the entrance of Zhaoqing Mansion. It was built in Song Chong and the first year (1118). The ancient Duanzhou was once the seal of Zhao Xuan, the Hui Zong Zhao Xuan. After Zhao Xuan inherited the throne, he should be invited by Guangdong to pass the judgment of Yan Xuan, and give a book "Zhaoqing Mansion". Shouchen built a high platform in front of the mansion, built a building, dedicated to the imperial book, and became the mansion city building, known as the "Yushu Building". Tomorrow, when Shou Huangyu in County 1662 was rebuilt, it was renamed the Liju Building. The building has a built-in copper pot dripping, a drying copper bell, and a big rattan drum to report the moment. The building was converted into the Yongming Palace by Zhu Yuqi, the emperor of Nanming Yongli. In early 1926, the building was the station of the Ye Ting Independence Group.
