Zhengding (), originally Zhending (), is a county in southwestern Hebei Province, North China, located approximately south of Beijing, capital of China. It is under the administration of the prefecture-level city of Shijiazhuang, the capital of the province, and has a population of 594,000. Zhengding has been an important religious center for more than 1,000 years, from at least the times of the Sui dynasty to the Qing dynasty. It is the founding place of several major schools of Chan Buddhism. However, many former religious building complexes have been severely damaged throughout history. A noted temple is the Longxing Monastery, where the historical building ensemble has been preserved almost intact. Furthermore, four famous pagodas, each with its own architectural style, are still standing. Archeological finds indicate that the area of Zhengding County has been settled since the early Neolithic Period. During the Spring and Autumn period, the capital of the Xianyu Kingdom was located in the area. Under the Han dynasty, the county was the site of Dongyuan, where the emperor Liu Bang led a siege during Chen Xi's rebellion in the early 190s BC. In the year 256 (Western Jin dynasty), the Changshan Prefecture was established in the county. In 923, during the Five Dynasties and Ten Kingdoms, the prefecture was renamed Zhengding Prefecture, which was later rearranged into the Zhengding Prefecture and Zhongshan County. Zhengding County was created during the Qing Dynasty, in 1723. In 1949, the county was subordinated to Shijiazhuang Prefecture and in 1986, it came under the jurisdiction of the City of Shijiazhuang. The current Chinese Communist Party (CCP) general secretary and Chinese president Xi Jinping was in charge of Secretary of the county Party Committee between 1983 and 1985. As a princeling, son of Xi Zhongxun, he was assigned to this rural area on his own request. He is credited with having a Qing dynasty style mansion constructed in the area for the filming of Dream of Red Mansions. Zhengding County ranges from in elevation.
