In the early Warring States period, there were more than a dozen countries in the Eastern Zhou Dynasty, among which Qi, Jin and Chu were the strongest countries, occupying four parts of the world. Sun Tianheng, the fifth generation of Tian family of Qi Guoqing, defected to Chen Wan, joined hands with Bao family, destroyed Luan and Senior Two, who were authoritarian at that time, and usurped the state power of Qi (Tian Dynasty Qi in 386 BC).

Later, with the rise of Yan State and the revival of Qin State, other small countries were gradually annexed or became vassal states. By the middle of the Warring States period, the remaining seven great powers of Qin, Chu, Han, Zhao, Wei, Qi and Yan were called the Seven Heroes of the Warring States Period.

Xiang, also known as Xiangbang and Prime Minister, is the first of all officials. A general, also known as a general, is the head of a military attache.

In the second year of King Wu (309 BC), the State of Qin began to set up a prime minister. The most distinguished prime minister was Xiangbang, and the highest military post was Liang Zuo at the beginning. It was not until King Qin Zhao established a general. Chu has always regarded Lingyin as the highest official position, or the Lord as the second highest military attache. The second-level military attache in various countries is Wei, or Guo Wei.
