The opposition between the Northern Wei Dynasty and the Song Dynasty is the return of the Southern Dynasty to the Northern Dynasty.

The Southern and Northern Dynasties (AD 420-AD 589) was a split period in the history of China, which began in AD 420 when Emperor Wudi of the Eastern Jin Dynasty established the Southern Song Dynasty and ended in the Sui Dynasty in AD 589. During this period, he inherited the Eastern Jin Dynasty, the Sixteen Countries of Wuhu, and then the Sui Dynasty. Although the Northern and Southern Dynasties changed dynasties, they maintained confrontation for a long time, so they were called the Northern and Southern Dynasties. The Southern Dynasty (420-589 AD) included four dynasties: Song, Qi, Liang and Chen. The Northern Dynasties (439-589 AD) included the Northern Wei, the Eastern Wei, the Western Wei, the Northern Qi and the Five Dynasties. It can be said that it is basically the same time, but the geographical location is different.

The Northern Wei Dynasty (386 ~ 557) was the first dynasty in northern China today. Also known as Hou Wei, Tuoba GUI and Wei Yuan. Tuoba Xianbei was established with Pingcheng as its capital (now Datong City, Shanxi Province).

Southern Song Dynasty (420 ~ 479) is the name of an ancient dynasty in China. In 420 AD, Song Wudi established the Eastern Jin regime. The country name is Song, and the capital is Jiankang (now Nanjing).

In the seventh year of Taichang in the Northern Wei Dynasty (422 in the third year of Song Yongchu), from October to April the following year, the northern Wei army captured the war in the strategic place south of the Yellow River in the Southern Song Dynasty.

When Emperor Wudi of the Eastern Jin Dynasty defeated the later Qin Dynasty, Yuan Di Tuoba Si failed to save Qin due to defeat. Although he sent envoys to make peace, he never forgot the southern expedition. In September of the seventh year of Taichang, Emperor Wei heard that Emperor Wu of Jin proclaimed himself emperor and died, that is, he wanted to send troops to take Luoyang, Tiger Prison, Sliding Platform (now northeast and northwest of Luoyang, west of Sishui Town, east of Huaxian County) and other southern parts of Song He, and then seize Jiangnan. Doctor Wei proposed a toast, thinking that although Emperor Wu of Song was dead, his henchmen were still there. It was better to wait for his powerful officials to fight for power and gain, and then order him to start his career. Di Wei refused to accept it, and his life was ordinary. Jin general Jin Du Song Junzhou, Wu Jun general Gong led troops to attack Song State.

10, Emperor Wei did not adopt the strategy of attacking the city first, but ordered Jin and others to ride 20,000 steps across the Yellow River and camp east of the sliding platform according to Jin's proposal of attacking the city first. At that time, Mao Dezu, the champion general of the Song Dynasty and the state secretariat, was guarding Tiger Prison City, and the Song Taishou Wang, who was guarding the slipway, was in a hurry. Mao Dezu sent Sima Zhaiguang and others to ride three thousand soldiers to save him. Wei Jun attacked Cangyuan (now northwest Kaifeng). Kim and others attacked the sliding table, but they failed. Please send more troops. Wei Di was angry and blamed him. He led more than fifty thousand troops to support him. 1 1 month, he ordered Prince Tuoba GUI to lead his troops to stop attacking. King and others were afraid to blame, so they attacked the sliding table and pulled it out. Wang ran away. Di Wei took the dog's ear as the secretariat of Yanzhou, guarding the sliding platform. Jin and others breached Zhaiguang's tulou in the east of Tiger Prison and advanced to Tiger Prison City. Wei Emperor also sent Heidui General to take 3,000 people to Tunheyang (now northwest of Meng County) in Li Shidan to find Jin Yong (now northeast of Luoyang, northwest corner of Wei and Jin Dynasties). Mao Dezu sent generals Wei Zhen Huang Dou and others to defend along the river. In December, when he arrived in Jizhou (now Hebei), he sent Chu Bing general Shu to cross the Yellow River from the plain (now southwest of Shandong Plain) and attack Qing and Yan States. Liu Cui, the secretariat of Yuzhou in Song Dynasty, sent troops to Xiangcheng (now Shenqiu, Henan Province), Wang Zhongde, the secretariat of Xuzhou, led the troops to defend Wei Jun in Hulu (now southeast of Yutai, Shandong Province), and Wei Di sent Middle-series Eqing to Fei Da for the week of the 7,000-strong meeting. Uncle Sun Jian crossed the Yellow River in the south, and his army was in the southwest of Pingping. During the Song Dynasty, Yan Xu, the secretariat of Yanzhou, abandoned Yin Mao (now southeast of East Asia) and fled to the south. Taishan, Gaoping, Jinxiang and other counties (all in present-day Shandong Province) were all obtained by Wei Jun, and uncle Sun Jianjun entered East Qingzhou (governing Dongyang City, now Qingzhou), and Zhu Kui, the secretariat of Qingzhou in the Song Dynasty, sent an urgent envoy. Song Ting ordered Tan Daoji, the secretariat of Southern Yanzhou, to supervise the army to conquer various military forces and rescue Wang Zhongde, the secretariat of Xuzhou. Liu Yizhen, king of Luling in Song Dynasty, sent General Shen Shu of Long Xiang to the headquarters with 3,000 men to help at an appropriate time. In the same month, after crossing the Yellow River in Lishi, Wei will join forces with the Western Jin Dynasty, break through and March on Jin Yong.

In the first month of the eighth year, Jin Yong City in Song Dynasty was captured in Li Shidan, and it was the secretariat of Yuzhou, guarding Luoyang. Di Weinan swam to Ye (now southwest of Linzhang, Hebei Province). Sun Jian, the uncle of the Song Dynasty, entered Linzi (now the northeast of Zibo), and all the cities he visited collapsed. Zhu Kui gathers people to protect Dongyang City, while those who live outside the city live in danger and stay in the wild. When Wei Jun arrived, all the people hid, and there was no food, which was not good for the siege. Wei Emperor sent Diao Yong, the rebel general of the Eastern Jin Dynasty and the general of Jianyi, to assist him and take Qingzhou as the secretariat. Wei sixty thousand cavalry crossed the Yellow River and went straight to Qingzhou. Diao Yong recruited 5,000 soldiers to comfort the people, and all the people gave food for the army. In March, Xi Jin, Gong Sunbiao, etc. * * * attacked Tiger Prison, and Emperor Wei sent troops to help. Mao Dezu dug a deep tunnel in the city and walked out of Wei's encirclement in six places. He recruited 400 people who dared to die, ordered Fan Daoji and others to join the army, and then went out from the tunnel to attack Wei Jun's array, killing hundreds of people and burning their weapons. Wei Jun retreated, dispersed and gathered, and rushed to Hulao Pass. In the Western Jin Dynasty, three thousand soldiers rode from Tiger Prison to attack Xuchang (now Xu Changdong, Henan Province), but the satrap Song Yingchuan, Li Yuande and others failed. Mao Dezu sent troops to fight with GongSunBiao and killed hundreds of Wei soldiers from morning till night. After the Jin army returned from Xuchang, it joined forces with GongSunBiao to attack Dezu, killing more than a thousand people, and Dezu sealed the city and stuck to it. Emperor Wei also sent more than 10,000 people across the Yellow River from Baisha (now near Puyang) to the south of Puyang (now southwest of Puyang). Gongba's army was locked in prison with the tiger and failed to win quickly. Mao Dezu had an old friendship with GongSunBiao, and suffered from his ingenuity, so he communicated with him and reported to Jin Mi that he had a conspiracy with Dezu. Kim doubts, tell. A surname Wei ordered Wang Liang to say that Sun Biao was not using troops properly. Emperor Wei believed his initial suspicion and ordered his watch to be killed at night, but he kept it a secret because of the war. Uncle Sun Jian rode around Dongyang City with 30,000 troops, and there were only 1500 soldiers and civilians in the city. Zhu Kui and others tried their best to stick to it and beat Wei Jun repeatedly. Wei Bu arranged around the city for more than ten miles and captured the attacking tools. Zhu Kui made a quadruple graben, Wei Jun made a triple graben, and then besieged the city. Zhu Kui sent someone to attack from the tunnel and overturned the plane crash with marijuana and sola, thus destroying it. Wei Jun continued its siege for a long time, and the attack became more and more urgent. There are many casualties in the city, and it is at stake. From Tandaoji to Pengcheng (now Xuzhou, Jiangsu), Shi Si and Qing states were in an emergency, but there were not many troops to save them. Qingzhou Road is near, and Zhu Kui's soldiers are weak, so he went to rescue with Wang Zhongde first. Liu Cui sent Li Yuande to recover Xuchang. Di Wei arrived in Hanoi (now Qinyang, Henan) and sent Yi Lou, the secretariat of Bing, to help Jin attack Hulao Pass. Mao Dezu supervised the soldiers to improvise and resist stubbornly.

In April, Di Wei went to Tiger Prison and saw Song Jun hanging a rope by the river to get water. Knowing that there was no water in the city, he ordered a boat to be connected to the river with a chariot (siege vehicle) on it, which was the only way to get water. After two days, the prison army attacked the city and failed, so they went to Luoyang. Uncle Sun Jian attacked Dongyang City and destroyed its northern city by about 30 steps. Diao Yong suggested entering quickly. Uncle Sun Jian forbid it. When the weather was hot, Wei Jun was infected. I heard that Tan Daoji and others were coming. Uncle Sun Jian and others burned the camp and equipment and retreated to the slide. Tan Daoji went to Dongyang, because of the delicious food, it was impossible to catch up. It is difficult to leave Yangcheng to the east of Zhu Kui, and it is also difficult to move the town to its city (now the northwest of Laoshan Mountain in Shandong Province). In April, Di Wei returned to Hanoi and then arrived in Du Gao (now Jincheng, Shaanxi). Uncle Sun Jian marched west from the slipway, and * * * attacked the tiger prison. At this point, Hulao Pass was besieged for about 200 days, Song Jinbing died, and Wei continued to send more troops. Wei Jun destroyed its outer city, Mao Dezu refused to build a city in the city, and Wei Jun destroyed it. Mao Dezu only defended one city and resisted day and night. Tan Daoji was stationed in Hulu, Liu was stationed in Xiangcheng and Shen Shu was stationed in Gao Qiao (now in the northeast of the East China Sea in Jiangsu Province). They were all afraid of Wei and did not dare to enter the customs. Wei Jun dug deep and drained the well water in the city. The defenders in Tiger Prison are thirsty and hungry, and the situation is extremely bad. Many people died in the Wei Jun epidemic, but they rushed out and eventually fell into Tiger Prison City, capturing Mao Dezu, Zhai Guang and other generals, but Fan Daoji led 200 people to break through and return to the south. Song Si, Yan, Yu and other counties (now Shandong and Henan) all entered the Northern Wei Dynasty. In November of that year, Wei Jun attacked Xuchang and Ruyang in the Song Dynasty (now the northwest of Henan Shangshui), and because of the death of Emperor Wei Mingyuan, he attacked the battle of Henan in the Song Dynasty.

In this battle, the Northern Wei Dynasty took advantage of Liu Yuxi's funeral to launch an all-round war and attack on a large scale. Finally, it concentrated its forces on besieging Tiger Prison and finally won the important town of Henan. Song Jun was good at guarding the city and resisted tenaciously, which made Wei Jun pay a heavy price.
