Duke Ping of Jin (姬; pinyin: Báng Zhīng Đ Mourning the Prince. Reigned from 557 BC to 532 BC. During his reign, the Jin state of Han Zhao Wei and other Shiqing forces were powerful, the status of the Gong clan declined, and the Jin state lost its hegemonic status. After the Song Dynasty held a general assembly of soldiers (in the twelfth year of the Duke of Jinping, that is, in 546 BC), the states of Jin, Chu, Lu, Song, Wei, Zheng, Chen, and Cai held a general assembly of soldiers in the Song Kingdom, and the two kingdoms of Jin and Chu were the main alliance. After that, due to the decline in the strength of the Jin state, the internal contradictions between Chu and Liu were fraught, and the war between the great powers was temporarily calmed down), in fact, the national strength had weakened, and the prince of the State of Chu was besieged and killed by the prince of Chu (the prince of Chu, Ao Ao, was ill, and the prince took the opportunity to visit the palace to visit his illness and kill him to establish himself as a king), and pinggong not only could not fight but intermarried with him, personally sent his daughter to marry, and also sent the ruling secretary all the way to the state of Chu. This is much different from the later Han Dynasty and Tang Dynasty using princesses and relatives! If king Chu Ling had not died early, the Jin state would have submitted to the Chu state, just as the Southern Song Dynasty had declared himself a vassal to Jin (in 1141 AD, the Song Jin peace agreement, the Song Emperor declared himself a vassal to Jin, and the Jin Dynasty made the Song lord emperor. Emperor Gaozong of Song stated in the Oath of Emperor Gaozong of Jin that "the subjects construct words ... That is, by grace, Xu Beifang, the descendants of the world, and the festival of the subjects. ") where just sacrificed the daughter thing.
The Jin Dynasty was once the most powerful country in the world, and the harm of stopping the army was so great. Therefore, whether a country is strong or not is closely related to whether the monarch is wise or not.
