Situated on the north bank of the Yangtze River near Zhongxian County, the 300-year-old Shibaozhai is a huge crag over ten meters high. Since its rectangular shape looks like a huge seal, it is called 'Jade Seal Hill'.
Atop the hill is a temple called 'Lanrou Hall'. A twelve-story pagoda-shaped wooden pavilion contains a staircase leading up the way from ground to the hilltop, which is otherwise difficult to reach.
Built along the mountain slope, Zhongxian (Loyalty County) boasts many historical sites. The county is so called because there appeared two loyal officials: the one is Bamanzi, a general of Ba dukedom during the Warring States Period, and the other is Yan Yan, a brave general of Western Shu during the Three-Kingdoms Period (220-280).
Apart from the tombs of these two loyal officials, there are still many other impressive buildings, such as the Taibao Temple dedicated to Qin Liangyu, a woman general noted for her heroic resistance against the Qing army, and the Hall of Four Worthies built in memory of the four Tang-dynasty worthies: Bai Juyi, Liu An, Li Jifu and Lu Zhe.
