What does "Zhongshan" mean?

The name of China in Zhongshan during the Spring and Autumn Period and the Warring States Period. In the spring and autumn period, it was called Xianyu, a genus, belonging to the tribe with the surname Zi, but some people thought it was Ji. There are many records about fresh risks in the Jin Dynasty in Zuo Zhuan. The name of Zhongshan first appeared in Zuozhuan for four years. During the Warring States Period, Zhongshan was in Lingshou, Pingshan and Jinxian areas of Hutuo River Basin. In 465438 BC+04 BC, Zhongshan Martial Arts was established in ancient times (now Jinzhou, Hebei). In the thirty-eighth year of Wei Wenhou (408 BC), Wei attacked Zhongshan and sent his son to attack it. Historical Records says that Zhongshan later rejuvenated the country. Ancestors may think that Sun Yat-sen was Ren Wei after the restoration of the country, but according to inscriptions on bronze, Sun Yat-sen was indeed a descendant of Wu Gong at the end of the Warring States Period. During the Warring States Period, Zhongshan and Song were both powerful countries after the Seven Heroes. According to historical records, Zhongshan built the Great Wall and Sun Yat-sen was appointed by King Zhou. In 323 BC, Sun Yat-sen was crowned king with Korea, Yan and other countries. Zhongshan became Zhao's confidant because of its proximity to Zhao. In 3 14 BC, the state of Yan was attacked by the "children's rebellion", and Zhongshan also sent troops to seize a large area of land. Since 307 BC, King Wuling of Zhao has attacked Zhongshan every year, weakening Zhongshan. In 30 1 year BC, Zhongshan Jun was threatened by Zhao and attacked Qi. In the fourth year of Zhao Huiwen (295 BC), Zhao took advantage of Qi's southward attack on Chu and wiped out Zhongshan in one fell swoop. After the restoration of Zhongshan, he passed away and died. There are not many historical materials of Zhongshan handed down from generation to generation, only in books such as Warring States Policy and Lv Chunqiu. In the Qing Dynasty, Wang Xianqian compiled these historical materials into the Table of Zhongshan Prefecture in Xianyu.
