Which city is Changshan now?

Changshan is now Shijiazhuang City, Hebei Province.

Changshan County was also called Hengshan County and Changshan County in some periods. It is an administrative division of China in ancient times, and its scope has changed in the past dynasties, but it is generally centered on Shijiazhuang City, Hebei Province today. Specifically, it is roughly at the boundary between the East Ancient City and the West Ancient City in the northern suburb of Shijiazhuang, which was the case after the war, that is, the county seat of Yuanshi County in Shijiazhuang today. The name of Changshan was first seen in the Warring States Policy, belonging to the State of Zhao.

After Qin Shihuang captured Zhao, Hengshan County was established, but the scope was smaller, excluding Hengshan in the north, and it was located in Dongyuan County (now the east of Shijiazhuang City). In the Western Han Dynasty, Emperor Gaozu lived along the county, and later he was renamed Changshan County to avoid Liu Heng, covering Hengshan Mountain in the north and Fengshan Changgu in the south. However, in the fourth year of Emperor Ding Yuan of the Han Dynasty (1 13), the four counties near the town were classified as the town, and the county administration of Changshan County moved southwest to Yuanshi County, belonging to the secretariat department of Jizhou.

In the 13th year of Jianwu (37 years), Emperor Guangwu of the Eastern Han Dynasty merged Zhending into Changshan County, and the county name was renamed Changshan County. The jurisdiction between Zhongshan State, Zhao State and Julu County has changed, but the county has been reduced to 13, and the county is still in Yuanshi County. In the Western Jin Dynasty, Leping County was divided into the southwest of Changshan County, and yuanshi county County belonged to Zhao State, and the scope was further narrowed. In the early Han Dynasty, the county was moved back to Calm County (now the East Ancient City of Chang 'an District, Shijiazhuang City). Along the Western Jin Dynasty, the number of counties decreased to 8, but Hengshan was still in the northwest of Shangquyang County.

The Sixteen Countries and the Northern Dynasties basically followed the county system and belonged to Dingzhou, and the Northern Zhou Dynasty was renamed Hengzhou. After the reunification of the Sui Dynasty, it was also called Hengshan County, and there were 8 counties in the county, and the rule remained the same. In the early Tang Dynasty, it was called Hengzhou. The first year of Tianbao (742) was changed to Changshan County. In the fifteenth year (756), Changshan County was renamed Pingshan County. In the first year of Gan Yuan (758), Pingshan County was abandoned and Hengzhou was restored. Later, in order to avoid Tang Muzong, it was changed to Zhou Zhen. In the Northern Song Dynasty, it was promoted to Calm House, and Changshan was no longer the county name.
