In other words, Ji Chong 'er, the eldest son of the State of Jin, fled abroad for 19 years because of the civil strife in the State of Jin, and finally returned to the State of Jin. He is the Jin Wengong of later generations. Let the state of Jin finally become the first of the five tyrants in the Spring and Autumn Period. How powerful is this country? Later, the state of Jin was divided, and it became one of the three families of Korea, Zhao and Wei, or one of the seven heroes of the Warring States. You will know how tough this state of Jin is. Zhao Kuo, an armchair strategist in later generations, and Sun Bin, who besieged Wei to save Zhao, all belonged to the State of Jin. Let's go on to talk about Zhong Er, the son. At that time, there was a saying that there was no righteous war in the Spring and Autumn Period. Every country wants to be strong and become the overlord of the Central Plains. Later, in the Warring States Period, Yi Chang and Su Qin made a joint venture with Lian Heng, which made many countries pursue their own interests. This is another story. Let's just say that Zhong Er's exile is extremely difficult. When he arrived in the state of Chu, the king of Chu once treated him very well. Once again, the king of Chu joked with him and asked him, how can you repay me after I treated you so well? Zhong Er said that you have plenty of beauty products here, and treasures are also produced from you. Zhong Er has nothing to repay. In the future, if the State of Jin and the State of Chu meet on the battlefield, I will take the initiative to retreat 9 miles to show my courtesy and return your kindness today. Later, the State of Jin and the State of Chu really met on the battlefield. And Zhong Er really retreated 9 miles as a way to lure the enemy. In the end, he defeated Chu State in Chengpu and became the overlord of the Central Plains. This is the story of staying away from home.
