Zheng Guo of the Qin Dynasty Introduction, where is the ancient Zheng State ?

The Qin Dynasty did not have Zheng Guo. It was a vassal state during the Spring and Autumn Period of the Eastern Zhou Dynasty and the Warring States Period.

Zheng Guo was one of the important vassal states from the Western Weekend to the beginning of the Warring States Period, surnamed Ji, an earl. In 806 BC, King Xuan of Zhou sealed his younger brother Ji You Yu Zheng, for Zheng Huan Gong, the initial fief in the area of Fengxiang in present-day Shaanxi Province, and later moved to the area of Huaxian County, Shaanxi Province, when King Zhou Ping moved eastward, Zheng Guo has moved to the area of Xinzheng, Henan.

In 771 BC, Dog Rong killed King You of Zhou and Duke Zheng Huan, and the succeeding Duke of Zheng Wu protected King Ping of Zhou as he moved eastward, and took the opportunity to destroy the kingdoms of Dongyu, Yi, and Hu, and moved Zheng to Xinzheng between He, Luo, Ji, and Ying. After Zheng Zhuang Gong ascended the throne, Zheng Guo began to be strong, and Qi and Lu formed an alliance to pretend to kill the Song Dynasty, due to the power of Zheng Guo, Zhou Tianzi tried to decompose the power of Zheng Zhuang Gong to cause Zheng Zhuang Gong to be dissatisfied and Zhou Zheng made enemies, Zheng Guo defeated Zhou, Yu, Wei, Cai, Chen in the battle of Jiangge, and defeated Song, Chen, Cai, Wei, Lu and other countries in 719 BC, making Zheng Guo the most powerful vassal state at that time, known as "Zheng Zhuang Gong Xiaoba".

After the death of Zheng Zhuang Gong, his son Li Gong expelled the prince and established himself as the king, Zheng Guo was in turmoil, and Zheng Guo gradually declined, and in the era of Zheng Mu Gong, Qi Mu took turns to govern and control the power of the country, and Zheng Guojun was in great decline. Zheng State, as a place of four wars, was coerced by Jin and Chu, and was almost unpeaceful every year. During the period of Zheng Xianggong, the state of Chu once captured the state of Zheng, and the prince of Xiang endured humiliation and survived the country.

During the reign of Zheng Jiangong, Zheng Guo appointed Zi Chuan as the prime minister to govern, cast criminal tripods, develop the economy, and rescue the people, so Zheng Guo became rich and strong again. After the three families were divided, South Korea became the biggest threat to Zheng Guo. In 423 BC, Zheng Yougong had just succeeded to the throne, Han Wuzi came to attack Zheng and killed Zheng Yougong, and later Yougong's younger brother Rugong returned to the country and had wars with the Three Jin Dynasty many times.

In 375 BC, the Marquis of Han Ai led an army to capture Zheng again, and Zheng Guo was destroyed, and the country was incorporated into Korea.

Zheng Guo was from the Zhou Dynasty.

Zheng State (806 BC, 375 BC), a vassal state surnamed Ji of the Zhou Dynasty.

Capital: At the beginning, it was Zhengyi (now Huazhou District, Weinan City, Shaanxi Province), and in 774 BC (the eighth year of King Youyou of Zhou, the thirty-third year of Zheng Huan Gong) moved the capital to Yuyi, and later built the capital of Xinzheng, Henan.

Zheng Guo is famous for its developed economy, sound legal system, democratic politics and poetic and musical culture, and is one of the important origins of China's legal system and Legalist thought.

In 806 B.C. (the twenty-second year of King Xuan of Zhou), Ji You, the younger brother of King Xuan of Zhou, was enthroned near the capital Haojing, with the country name Zheng and the capital city of Qilin (now Huazhou District, Weinan City, Shaanxi Province).

In 774 B.C., Duke Zheng Huan moved Zheng to Henan and established his capital in Zheng (now Xinzheng City, Henan Province), with its main territory located in the area of present-day Zhengzhou, Henan.

The demise of Zheng Guo

Jeong's biggest enemy is already the emerging South Korea. However, Zheng Guo still had civil strife and infighting, and Zheng Aigong was killed by the countrymen; South Korea attacked Zheng and killed Yougong. So the people of the country set up Gongzi Xiao, the younger brother of Yougong, as the king, for Zheng Xianggong.

Han Fei said that the Dazai Shin Zheng incident occurred in Zheng Guo, and the details of this matter are difficult to verify. During the reign of Chung Hsi-gong, the war with Korea was won and lost, and the situation improved for a time.

In the fifteenth year of the Emperor's reign, Han Fa Zheng took Zheng Zhiyongqiu; In the sixteenth year of the Emperor's reign, he defeated Han Yu and lost the army; Twenty-three years of Gonggong, surrounded Han Yang Zhai. In 375 BC, Jeongguo was destroyed in Korea.

The above content reference: Zheng Guo.

Zheng was originally a vassal state of the Jin state, but as a result, he befriended the state of Chu, and the state of Jin sent troops to teach Zheng Guo a lesson, and the state of Qin was allied with the state of Jin at that time and was obliged to send troops with the state of Jin.

Zheng Guo offended Jin Guo with two things. First, when Duke Wen of Jin fled and passed by Zheng Guo, Zheng Guo did not treat him with courtesy; Second, in the battle of Jin and Chu Chengpu in 632 BC (the twenty-eighth year of Lu Xugong), Zheng sent troops to help Chu. As a result, the Battle of Chengpu ended in the defeat of the Chu State.

Zheng Guo felt that the situation was not good, and immediately sent Zirenjiu to envoy Jin Guo to make peace with Jin. In May 632 BC, the Marquis of Jin and Zheng Bo formed an alliance, but in the end, they failed to influence the Jin state.

In order to compete for hegemony, Jin Wengong (Chong'er) launched this war two years later. The Jin State united with the Qin State to besiege the Zheng State because the Qin State also had to compete for hegemony at that time, and it also needed to expand outward. The Battle of Chengpu, which took place in 632 BC, was in fact a war between two major military groups.

On one side was the allied forces of Jin, Song, Qi, and Qin led by Duke Wen of Jin, and on the other side was the allied forces of Chu, Chen, Cai, and Zheng, which were dominated by Chu (Zheng did not nominally participate in the war, but had actually sent troops to Chu in advance).

Two years later, when the Jin State launched a war against the Zheng State, it was natural to look for a competent partner. At this time, the Qin State also had the desire to expand outward, and it could "get a handful" (in essence, this war had little to do with the Qin State), so the alliance between Qin and Jin was inevitable.

Because Zheng Guo was rude to Duke Wen of Jin, and while he was attached to the Jin State, he was also attached to the Chu State. Qin Guo wanted to take the opportunity to sow discord between Jin and Zheng Guo, and wanted to destroy Zheng Guo by linking Jin.

If you use the original text, it is: with its rudeness to Jin, and second to Chu.

In 806 BC, King Xuan of Zhou's younger brother Ji You, as the royal Situ, forcibly occupied a total of ten provinces in the east of Heluo, and established the Zheng State, which was for the Duke of Zheng Huan and the capital of the country"Zheng", in the no 棫 (pronounced: elm) forest (now Fengxiangnan, Shaanxi).

In the first year of King Ping of Zhou (770 B.C.), Duke Zheng Wu moved Zheng Guo to the east of the capital of Yu and Yi (now Huayin City, Shaanxi, east of Huaxian County).

In the sixth year of King Hui of Zhou (671 BC), Duke Wen of Zheng officially established the capital of Xinzheng (in today's Xinzheng City, Henan Province, 38 kilometers south of Zhengzhou City). Bedu oak. There are temples and palaces in the national capital Xinzheng, and there are 5 gates on the city wall.

Zheng Guo's contemporary location was in a large area south of the Yellow River in present-day central Henan Province. It can be seen that when they were wiped out by the newly rising Korea during the Warring States Period, the Yin clan, which belonged to the Zheng Guo clan, multiplied and grew in the Feng Yi area of Shaanxi. Then, with Feng Yi as the center, it was successively spread to all parts of the country, forming today's Yin family everywhere.

The Wang clan lived in Fengyi County (now Dali County, Shaanxi Province).

It turns out that the surname Han is our enemy!

The Zhengguo Canal is a large-scale irrigation project. In 246 BC, King Zhenggang of Qin ascended the throne, and King Han Huan Hui sent Zheng Guo, a water engineer, to Qin to implement the plan of "tired Qin" in order to induce Qin to spend manpower and material resources on water conservancy construction and was unable to carry out the eastern expedition. Zheng Guo designed and built an irrigation project for Qin to divert Jing water into Luoyang.

During the construction process, King Han's plan was exposed, and Qin wanted to kill Zheng Guo, Zheng Guo said: King Han asked me to be a spy at the beginning, but the completion of the canal was only for Han Yan's life of several years, and for Qin to build a merit for eternity ("Hanshu Gou Xianzhi"). Qin Wangzheng thought that Zheng Guo's words made sense and asked him to continue to preside over the project.

It took about 10 years to complete the project. Because it was designed and presided over by Zheng Guo, it is called Zheng Guoqu.

Zheng Guo Canal Project, west from the west foot of Zhongshan Gukou (now northwest of Chuantou Village, Wangqiao Township, northwest of Jingyang, Shaanxi), Zheng Guo made a stone weir dam in the valley to raise the water level and intercept Jing water into the canal. Taking advantage of the topography of slightly high in the northwest and slightly lower in the southeast, the main trunk line of the canal stretches from west to east along the southern foot of Beishan, flows through Jingyang, Sanyuan, Fuping, Pucheng and other counties, and finally flows into the Luohe River in the south of Jincheng Village, Pucheng County. The total length of the trunk canal is nearly 300 miles.

Along the way, the mountains and rivers are cut off, and the smelted water, clear water, turbid water, and Ishikawa water are collected into the canal to increase the amount of water. In the northern part of the Guanzhong Plain, an irrigation system like a spider's web is formed between Jing, Luo, and Wei, so that the Guanzhong Plain, which is high in drought and lacks rainfall, can be irrigated.

After the completion of the Zhengguo Canal, it greatly changed the appearance of agricultural production in Guanzhong, and used the water to fill the silt to irrigate the brine land. It is to use the sediment content of Jing water for irrigation, increase soil fertility, agriculture, rapidly developed, rainfall is scarce, the land is barren Guanzhong, become rich in the world ("Historical Records, River Canal Book").

In 628 BC, the Jin monarch Chong'er had just died, and the funeral had not yet been held. At this time, Qin Mugong estimated that Zheng Guo's ally Jin Guo had no intention of interfering, so he wanted to take the opportunity to attack Zheng Guo. The army of the Qin State, led by the generals Meng Mingshi, Xi Qishu, and Bai Yibing, drove 300 military chariots and secretly drove towards the Zheng State, and soon entered the area of the Slippery Country, which must be passed.
