Beaten+joke

In fact, during the Spring and Autumn Period and the Warring States Period in China, Zheng was easily defeated by other countries when competing for hegemony. Because Zheng Dangshi is sandwiched between two big countries, its national strength is not strong and it can only be beaten, so there is a joke of "eating and sleeping to beat Zheng" in later generations.

At that time, Zhong Er and Jin Wengong went to the State of Jin. At that time, Zheng Wengong impolitely asked Zhong Er to leave quickly. Later, a war broke out between Chu Jin and Chengdu, and the State of Jin won. Unfortunately, when Zheng sent troops to help Chu, Jin couldn't bear it, so he asked Qin to fight Zheng together. Thanks to the retreat of Qin Shi, the country was not destroyed.

Later, after Chu Zhuangwang of Chu acceded to the throne, Chu began to become powerful. Zheng's swing slowly fell to Chu, and then Chu and Jin went to war. In order to understand the difficulties of his allies, Jin went to attack Zheng. Fortunately, Chu and Zheng joined forces to defend themselves.

Before long, Jin saw that Zheng was a vassal state of Chu, so he sent troops to attack Zheng to stop Chu from developing northward.

In 607 BC, the State of Chu told Zheng to attack the State of Song and was defeated. In order to avenge Song, Jin sent troops to attack Jin.

In 606 BC, Jin sent troops to attack Zheng. At this time, Chu was unable to send troops to help Zheng because of civil strife, so Zheng had to surrender and sign a Covenant with Jin.

In 599 BC, when Chu went north, it was this Zheng State that first attacked. Jin sent troops to help Zheng in time.

In 597 BC, Chu attacked Zheng again and besieged Zheng 17 days. Finally, Zheng Xianggong confessed to the King of Chu.

In just two or three decades, Chu attacked Zheng twice and Jin attacked Zheng five times. As a result, Zheng Mugong died, and formulated the national policy of "only being strong and obedient, advancing from Jin to Chu".
