After Jin Chenggong ascended the throne, he began to eliminate the negative impact of Jin Linggong's actions on the country and change the negative and decadent mental state of the people. He annulled the edicts issued by Linggong that endangered the people and the state, reduced taxes, punished those who aided and abused, released the innocent, relieved the poor, and restored the various orders that had been destroyed.

At that time, the treasury had become very empty, and the Jin people studied it and decided to solve the problem of poverty by starting with the root cause of poverty - the Jin people raided the homes of the villains, confiscated their property, and redistributed the land. The ministers also contributed a large amount of property to fill the deficit in the treasury.

Through the implementation of a series of measures that are beneficial to people's livelihood, the Jin Kingdom was able to regain its vitality in a short period of time. Seeing that the conditions were ripe, Jin Cheng led his army to the east, and the sword pointed directly at Zheng Guo.

In the spring of the third year of Lu Xuangong (BC606), the Jin army broke into the border of Zheng and went straight to Xinzheng. The Jin army was huge, and the sergeants had a strong will to fight, and the Zheng people did not dare to resist, so they opened the city gates. Zheng Guo originally broke away from the alliance because of the appearance of the tyrant of the Jin state, and now he returned to the alliance because of the death of the tyrant.

As mentioned earlier, after the defeat of Hanyuan, the Jin people were forced to accept an order from the Qin state, that is, to help the Qin people move Lu Hun Rong to the Heluo area. In the twenty-second year of the reign of Lu Xi (BC638), Qin and Jin moved Lu Hun Rong east to Yichuan. Lu Hun Rong started from scratch and established the Lu Hun Kingdom on the vast wasteland that was inaccessible.

Due to his nature and lack of materials, Lu Hun Rong worked hard to build his home while doing all kinds of robbery. Later, they found that it was not a bad thing to leave their homeland: the climate of the Central Plains was not as harsh as that of Hexi, the land was fertile and abundant, and the population was large and prosperous, and it was indeed a good place to make a living.

As their power grew, the scale and scope of Lu Hun Rong's activities also grew, and they eventually robbed the caravan of the Chu State, which no one could afford to provoke.

At that time, the state of Chu had just suffered a great mourning (Dou was framed to death, and that tragedy will be described in detail in the later chapter), and the people of Chu Zhuang and Doujiao regarded King Chu Zhuang and Doujiao as the culprits who caused the great funeral, and strong resentment permeated the sky over the Chu state. King Chuzhuang urgently needed a foreign war to divert domestic contradictions, so he raised troops to attack Lu Hun Rong. Lu Hunrong's country is not big and his military strength is not strong, but King Chuzhuang deliberately created a huge scene. Chu Shi defeated Lu Hun Rong in a battle and forced the other party to sign an alliance under the city.

The king of Chu Zhuang felt that he was still unsatisfied, and he said to his ministers: "Since the founding of the state of Chu, there has not been an army so close to the Eastern Zhou. The Eastern Zhou Dynasty is the symbol of China, and if the Chu State wants to rule the world, it must first destroy the Eastern Zhou Dynasty. Although the Chu army is not strong enough now, since there is such a good opportunity, it is better to go to the Eastern Zhou to inspect the atmosphere of the people in the next Zhou. ”

The Chu division immediately pulled out the camp and marched towards Chengzhou, and arrived at the southern suburbs of Chengzhou two days later. The king of Chuzhuang did not want to overstimulate the Zhou people, so he ordered the army to camp in place.

The Zhou people behaved quite calmly, perhaps because people had become accustomed to seeing all kinds of enemies appear outside the city. Wang Sunman was ordered by King Zhou Ding to bring gifts to the Chu people.

King Chuzhuang asked a question at the banquet to welcome the royal envoy: "Bugu heard that Dayu cast nine copper tripods to pacify Kyushu, and these nine tripods are now placed in the Taimiao of the Eastern Zhou Dynasty. What Bugu wants to ask is: Jiuding, which is known as the treasure of the world. How much does it weigh? ”

Wang Sunman replied: "The Zhou people think that Jiuding is Kyushu, and only God knows how heavy Kyushu is. Zhou has Kyushu in Germany, not in Ding. Xia people are virtuous, so they cast Jiuding; At the end of summer, there was a faint virtue, so it lost Jiuding. Jiuding moved to Shang and was worshiped by merchants for 600 years. Shang was tyrannical and immoral, so Ding moved to Zhou.

"The king has virtue, and although the tripod is small, it is immovable; The king has fierce virtue, and although the tripod is large, it is light and movable. Heaven blesses those who have wisdom and virtue in their hearts, and they must have a certain number and cannot be easily moved. When King Cheng established Cheng Zhou, Bu Zhou will be passed on for 30 generations and established for 700 years. Although Zhou De declined, the mandate of heaven did not change; As for the weight of the tripod, it is not allowed to be heard. ”

After King Chuzhuang sent Wang Sun Man away, he said: "It has only been more than 400 years since the founding of the Zhou Dynasty, and it seems that it is impossible to see the fall of the Eastern Zhou Dynasty. The descendants of the Chu State are going to work hard. ”

After leaving Cheng Zhou, the king of Chu Zhuang ordered Doujiao to lead his left army to invade Zheng in retaliation for the Zheng people's rebellion, and he himself led the rest of the army back to Chu.

On the way to Xinzheng, Doujiao heard that Zheng Mugong was seriously ill and that his time was short, so he said: "Let's withdraw the army!" Taking advantage of the danger of the people, it is not too late to wait for the successor to ascend the throne and then come to the crusade. ”

But his subordinates didn't believe that was what he really meant, because Doujiao was never a person who cared about the lives of others; It is believed that Doujiao was worried that something unfavorable would happen in the country, so he was anxious to find an excuse to return to China as soon as possible.

In the winter of that year, Zheng Mugong died.

After the death of Zheng Ligong, Zheng Wengong inherited his father's power and harem. He and Li Gong's concubine Chen Fei gave birth to Prince Hua and Gongzi Zang; Prince Hua was killed for his ambition and misconduct, and Gongzi Zang was killed after fleeing for his behavior that insulted the public family (Gongzi Zang is said to like to collect hats decorated with migratory bird feathers; Migratory birds migrate chronologically and are considered trustworthy animals; And the feather crown is the symbol of the previous judges. Gongzi Zang didn't learn anything, but he wore a feather crown and swaggered around, which seriously insulted the dignity of Zheng Guo's office, so he was killed). Zheng Wengong's concubine of Jiang Guo gave birth to Gongzishi, who was poisoned by the people of Chu. Zheng Wengong married Yu Su again, and gave birth to a son, Yu Mi, and a son; Gongzi Yu Mi died early, Gongzi defected to the Chu State, and later died in the Zhou Wang.

Zheng Wengong also had a cheap concubine named Yan Yao of the Southern Yan Kingdom, once Yan Yao dreamed that a messenger from heaven held an orchid in her hand and said to her: "I am your ancestor Bo Xiu, this is your child." Orchids have a national fragrance, and gentlemen like to wear it. ”

Soon, Zheng Wengong gave her an orchid, which was exactly the same as the one in her dream.

Yan Yao said: "The concubine already has your child, if you don't believe it, I can swear to the orchid." ”

Zheng Wengong said: "The widow believes in you. ”

At the end of the pregnancy period in October, Yan Yao gave birth to a baby boy, so Zheng Wengong named him "Lan", and this child was later Zheng Mugong.

Zheng Wengong expelled the sons of Qun in his later years, and Gongzi Lan was also forced to join the exile army. Gongzi Lan fled to the Jin Kingdom, and later returned to the Zheng Kingdom with the support of the Duke of Jin Wen.

At that time, Zheng Wengong was not sure whether to give the position of the prince to Gongzi Lan, and the doctor Shi Huang said: "I heard that Ji and Yao can form a good couple, and their descendants will definitely prosper." The surname Yao is Jiren, and the concubine of Houji is the surname Yao. Now, Gongzilan has become the nephew of a person surnamed Yao, and is sponsored by God, and her descendants will surely prosper. As a result, Gongzi Lan was made the crown prince.

When Zheng Mugong was seriously ill, orchids also began to wilt. In October, Zheng Mugong said: "I was born because of orchids; Lan is dead, and I should die! He cut off the roots of the flower and died a few days later. Prince Yi ascended the throne for Zheng Ghost Gong.

After Zheng Mugong's death, seven of his many sons gradually became political oligarchs in the country. Later, the world only knew that Zheng Guo had "Seven Mu", but did not know that there was Zheng Bo. Doctor Qimu controls state power just like the six secretaries of the Jin State, the three huans of the Lu State, and the Song Guohua Xiang. Later in the Qimu family, there was a great figure - Gongsun Qiao (Zi Chan, Zi Mei); When Gongsun Qiao died, Confucius wept bitterly and called him "the bereaved love of the ancients".
