My answer is as follows:

Dongyang, known as the "Northern Beam" in the Spring and Autumn Period, is a small border town of Wu, bordering Li Zhong of Chu. Wu Chu and China went to war because of the children's "mulberry leaf battle". Later in history, a big war triggered by a small incident was called "a humble dispute". In 22 1 BC, Qin Shihuang unified the world, accepted the suggestions of Prime Minister Li Si and others, and established a county system. Dongyang is the first county established. At that time, Dongyang County had a large jurisdiction, including parts of Jinhu, Hongze, Baoying and Xuyi counties, with more than 10,000 households in the country. At the beginning of Han Dynasty, Dongyang was promoted to county, which was under the jurisdiction of Wu Wang Liu Bi. When Emperor Wu was a county, he belonged to Linhuai County. At that time, the ecological environment was very good, with abundant water plants and herds of elk. Dongyang people often get twice the result with half the effort when planting rice in the wetland where elk play. During the Three Kingdoms period, Dongyang belonged to Wei first, then to Wu, and was the military center of confrontation between the north and the south. During the Jin and Southern and Northern Dynasties, Dongyang belonged to Linhuai County. In 573, due to frequent wars, a large number of people in the north moved south. In the Southern Dynasties, Chen recovered Dongyang County and merged it into Shanyang County. Dongyang City, which lasted for nearly 800 years, ended its historical mission and became a ruin.

Cities are carriers of civilization. A city dies, but the civilization it created will not die, and it will still exist in various ways. From historical documents and unearthed cultural relics, we can understand the glory that Dongyang City once created. For example, in 1974, a number of woodcuts were unearthed in the Han tombs in its suburbs, including 2 woodcuts of stars, 3 woodcuts of characters' stories and 3 woodcuts of acrobatics. This star map is the earliest existing comet map in the world, which records the operation of a comet in April in the fifth year (the first 44 years) of Emperor Han and Yuan, and has high academic value. In addition, the unearthed exquisite bronzing lacquer case, exquisite jade belt hook, exquisite dragon bronze ware, twenty-six bronze rights of Qin Shihuang, exquisite Boshan furnace, ant nose money, five baht money and other cultural relics all show Dongyang's profound cultural heritage.

Celebrities in Dongyang's history have exerted a profound influence on China's history and culture.

Chen Ying, a man of the hour in Qin and Han Dynasties.

In July 209 BC, Chen Sheng and Guangwu launched a garrison rebellion in osawa Township, and erected the banner against Qin. In September of the same year, Xiang Liang and Xiang Yu rose up in Wu, and led 8,000 Jiangdong children to fight against Qin in the north. Young people in Dongyang County were moved by the wind and killed the county magistrate sent by the Qin Dynasty, which quickly merged into an army of 20,000 people. Historical records call it "sudden emergence of a new army", and this idiom comes from it. Everyone recommended Chen Ying, a local magistrate in the county government, as the king. Chen Ying has always been cautious and low-key, refusing to show off. He went home to ask his mother for advice. His mother said to him, "I have been married to your family for so many years, and I have never heard that there are rich people in your ancestors." It is not a good thing to suddenly become rich and expensive now. You might as well be attached to something, and you can still be blocked when things are done. It is not easy to escape. " So, Chen Ying discussed with everyone and said, "The Xiang family is an aristocrat of the State of Chu and has been famous for generations. To do great things now, there is no appeal without a family as commander in chief. If you are attached to a famous family, you will be able to destroy Qin. " Hearing this, they all agreed. Soon, Xiang's army passed by Dongyang, and Dongyang Rebels joined in, becoming the main force against Qin.

When the State of Chu was destroyed by the State of Qin, some members of the Chu royal family went to Xuyi, including Chu Huaiwang's grandson Xiong Xin and granddaughter Chu Huanggu, who were herding sheep in Xuyi Mountain. Xiang Liang, Xiang Yu and Chen Ying found Xiong Xin, decided to restore Chu, made Xiong Xin king of Chu, and made Xuyi their capital, so as to command the uprising troops all over the world. Chen Ying was appointed as the "Upper Pillar State" (that is, the officer in charge of the three armed forces, ranking second only to the Prime Minister Ling Yin) to stay with the King of Chu, while Xiang Liang and Xiang Yu led the army to continue northward to fight against Qin Jun's main force, and Chen Ying became the nominal supreme military commander of the country, which attracted worldwide attention for a time. Later, Xiong Xin, the king of Chu, moved to Pengcheng, and Chen Ying continued to hold important positions. After Xiong Xin was deposed and killed by Xiang Yu, Chen Ying was subordinate to Liu Bang, unified the army to fight in the south and attack the city slightly, and became the founding hero of the Han Dynasty. Liu Bang established the Han Dynasty, named Chen Ying Tang, married Chen into the royal family, and his descendants were hereditary marquis. At that time, the princes with different surnames who followed Liu Bang to conquer the world were slaughtered, and few survived. Chen's family was so brilliant that it was due to Chen's farsighted decision, so she was included in Historical Records and Hanshu, and Shi Shuo Xin Yu Yuan Xian Pian listed her as the first person to be praised.

Empress Gillian of Emperor Wu of Han Dynasty

Chen Wu, Chen Ying's grandson, married Liu Pu, the elder sister of Emperor Jing of Han Dynasty, and gave birth to a daughter named Gillian, a cousin of Liu Che, Emperor Wu of Han Dynasty. On one occasion, Liu Pu held Liu Che in her lap and pointed to a large group of beautiful women coming from the palace to tease Liu Che and said, "Who will you marry in the future?" Liu Che said, "I want to marry Gillian." Liu Pu was extremely surprised and asked, "How did you treat her?" Liu Che said, "I want to build a golden house for her to live in." This is the origin of the idiom "A golden house hides a charming woman". Gillian really became the queen of Emperor Wu when she grew up. Liu Che and Gillian belong to a political marriage, and Liu Che, the eldest son, ascended the throne because of Dou Taihou and Princess Guantao who were in power at that time. Later, because he had no children, Emperor Wu of the Han Dynasty doted on Wei Zifu, and Wei Zifu gave him a son. Empress Chen was left out in the cold and retired to the palace gloomily. At that time, Sima Xiangru became popular because he was good at writing ci and fu, so he sent someone to give him hundreds of gold and asked him to write a fu for himself. Sima Xiangru wrote the famous Long Men Fu in the history of literature. Emperor Wu of the Han Dynasty saw this poem and was deeply moved, so he got back together with Queen Chen. The story of "a thousand dollars to buy Fu" is widely circulated in later generations.

Chen Jiao who assisted xelloss to ascend to the throne.

Chen Jiao, a native of Dongyang in the late Eastern Han Dynasty, was loyal and resourceful. Because there was chaos in the world, he went to Jiangdong and Dongcheng to avoid chaos. Sun Ce, Yuan Shu and others thought he was talented and wanted to use him, but he refused. After returning to his hometown, Chen Deng, the magistrate of Guangling, asked him to be a meritorious official in charge of official assessment and respected him very much. Sun Quan sent heavy troops to attack Chen Deng, who sent him to Cao Cao for help. At that time, Cao Cao held a wait-and-see attitude and saw that Chen Jiao was a talented person and wanted to keep him for his own use. Chen Jiao said: "The situation in our country is very critical. Even if we can't go to Qin and cry for seven days and seven nights like Shen, and finally let Qin send troops to save Chu, we must learn from Wei's suicide after the monarch was killed and abandoned, and put the monarch's liver and intestines into his abdominal cavity. " Cao Cao was moved by his sincerity and sent troops to relieve Chen Deng. Chen Jiao was eventually snared by the talented Cao Cao, and he was appointed as the magistrate of Pengcheng and Leling. A farmer was sentenced to death by the county magistrate because his father was seriously ill and killed a cow to pray. Chen Jiao said, "This is a dutiful son" and ordered his release. The magistrate of Shengwei County saw that there were thousands of people in the prison at that time, and many people were detained for a long time. Did not say that he was lenient as soon as possible and released in large quantities. Soon, he was transferred to the post of Prime Minister Changshi and became one of Cao Cao's confidants. He led the army to conquer Hanzhong and was promoted to Shangshu.

In 220 AD, Cao Cao suddenly died in Luoyang, leaving no imperial edict for the Crown Prince to succeed him. The ministers in Yecheng panicked and didn't know what to do. Chen Jiao stood up and said, "Wang Wei died of illness, and everyone panicked. When the prince is in grief, he should immediately accede to the throne in order to stabilize the people all over the world. And Wang Wei has other sons in Luoyang. If there is a coup, the country will be in danger. " So, he immediately made people prepare for the enthronement ceremony, and it took only one day to get everything ready. The next day, he was ordered by the Queen Mother to announce that Cao Pi had succeeded to the throne, and all the officials admired his shrewdness. Cao Pi said with deep feelings: "Chen Jibi has superhuman insight and strategy at a critical moment. What a great man!" After replacing Emperor Xian of Han Dynasty, Cao Pi was appointed as the official minister, the Tinghou of Gaoling, and was soon promoted to the official minister. Ming Di succeeded to the throne and made him the East Township Hou. He was promoted to Shi Zhong and Guang Lu, and later moved to Stuart.

Chen Qian, the founding hero of the Jin Dynasty

Chen Qian, the son of Chen Jiao, has his father's legacy, and he has been very clever since he was a child. Chen Jiao is a secretary, and Ye Liu is a servant, who is favored by Wei Mingdi. He sues Chen Jiao for his autocratic power. Chen Jiao was very worried and went home to express his worries and fears to his young son. Chen Qian said, "Lord, you are an important official. It doesn't suit his mind at the moment, and nothing will happen. At most, you shouldn't be an official. " Ming Di really didn't listen to Ye Liu's slanderers, and Chen Jiao worked until his death. Once, Xia Houxuan insulted Chen Qian in public. He smiled and took it seriously. Later, Xia Houxuan respected him very much.

Chen Qian was appointed as a businessman at first, and later he was promoted to Zhongshan Prefecture and Anping Prefecture with outstanding achievements. He was promoted to Sima, Changshi, Zhongcheng, Shangshu and Hou Ting. At that time, Shu attacked Longyou, and Chen Qian served as the commander of Shu with Shangshu. He led the army to conquer and defeated the Shu army. When Zhuge Dan rebelled, he used Shangshu to pacify Shouchun for General Anton. Worship the envoy to hold the festival and command the Huaibei army, and enter the Jue Guangling Hou. He was transferred to Jingzhou Military Department, Commander-in-Chief of the Army, and General Nan as an official. Emperor Wu of Jin took the place of Cao Wei, and Chen Qian was appointed as a chariot-riding general, appointed Gaoping county magistrate, moved to serve as a general, and served as commander-in-chief of Yangzhou military affairs, pretending to be Huang Yue, attacking and pulling the city, and breaking through the slaughter, thus establishing brilliant military achievements. My nephew, Chen Xing, followed him in the north and south, and sealed the Guanzhong Hou with excellent military exploits. In the early years of Xianning, he was promoted to Qiu and transferred to Fu. On one occasion, Chen Qian entered the DPRK to discuss personnel issues with Emperor Wu of Jin Dynasty. He said, "Hu Lie and Hong Qian are brave and foolhardy people, so they are self-righteous. They are not the people who can stabilize the border. Letting them guard the border will bring shame to the country. I hope your majesty will understand. " At that time, Hong Qian was the secretariat of Yangzhou and did not listen to Chen Qian's command. Emperor Wu of Jin thought that the relationship between them was not good, so he adopted Chen Qian's suggestion and appointed him as the secretariat of Liangzhou. Chen Qian privately shook his head, sighed, and thought the man was doomed. Later, the two really failed to have a good relationship with Qiangrong, and were defeated by Qiangrong, losing a lot of land. Emperor Wu of song regretted not listening to Chen Qian's advice.

Chen Qian is a great man with great achievements and a great minister. Xianning has been in the DPRK for three years. Please leave. Emperor Wu of the Han Dynasty regarded him as Xiao He of the Han Dynasty, but he didn't agree. He was crowned and many letters were published in recognition of his meritorious service. Later, he repeatedly requested that Emperor Wu of Jin agree to give him generous material treatment and special courtesy. Chen Qian died in the second year of Yuankang at the age of 8 1 year. At the time of his death, the imperial court chartered him to be buried in, and gave him posthumous title "Wu". At the funeral, Emperor Jinhui personally went to Simamen to see him off, looked at the faded coffin and kept wiping his tears.

Dongyang ancient city was listed as a cultural relic protection unit in Jiangsu Province on 1982. Regrettably, the rich cultural treasures of Dongyang ancient city have not yet attracted the attention of relevant parties, and they are still sleeping in the long river of history and have not been explored and utilized.
