Zi chan was a politician, thinker and teacher of Confucius in the Spring and Autumn Period. He is the grandson of Zheng Mugong. Zi chan did not sit on the throne at first. He also assisted two emperors. In these days, he has accumulated a lot of experience and managed this country. He is a very careful and observant person. At that time, Cai passed Zheng on his way home, so he decided to stop and have a rest for a while. You are welcome to entertain him personally, but this Cai is too arrogant. He was not modest when he came to other people's territory, and he also showed all kinds of disrespect, which made everyone very embarrassed. Zi chan's evaluation of Cai did not come to a good end. Indeed, Cai was later killed by his son. A person's personality will largely determine a person's life, or put you in a framework, but the general direction is certain. During Zi Chan's reign, we have to say that he was indeed a monarch, which restricted the nobles in many ways and improved the welfare of the people. Zheng's geographical position lies between Jin Chu, so a small country like Zheng needs to pay tribute to a big country every year. This expenditure is a protection fee, but every year, the people work hard and end up in other people's pockets, which makes the property very uncomfortable. Zi chan also formulated the first written law in the history of China? Criminal law? During his reign, no thieves came in if he didn't close the door at night, and the people's happiness was very strong, and the bad guys dared not come out to do evil. As the king of a country, we should not be too weak or too impatient. The property has found a balance between the two, so the country and the people are thriving. However, after Zi Chan died of illness, his son sat on the throne and his balance was broken. He is so weak that there are bad people everywhere.
