Emperor Wu of Song Wudi (363 ~ 422) was the founding emperor of the Southern Song Dynasty. The word Deyu, posthumous title sent slaves. Originally from Pengcheng (now Xuzhou, Jiangsu). Be in power for three years. Great-grandfather Liu Dongjin crossed the river and lived in Jingkou. His father, Liu Qiao, was a county magistrate Cao and died young. Liu is very poor. He lives by firewood, fishing and selling shoes. He used to be the champion of the northern government soldiers, Sun Wuji. In the third year of Longan (399), the former general Liu Laozhi joined the army, then suppressed the Sun En Uprising (see Sun En and Lu Xun Uprising), became a tired official, became a general of Jianwu, and became a magistrate of Pixian County. Huan Xuan relied on his father's ancestral wealth, seeking to seize state affairs. In the name of Sima Daozi and Yuan Xian, he became king in Jiankang, dismissed Liu Laozhi, an old general of the northern government, and promoted Emperor Wu of Song to suppress the rest of Sun En in the southeast coast. Emperor Wu of Song showed deference to Huan Xuan, and at the same time, he stood together in the northern government soldiers to resist. After Huan Xuan forced Andi to abdicate and usurp the gold, in the third year of Yuanxing (404), 27 people including Emperor Wu of Song, He Wuji and Tan rose from Jingkou, killed Huan Xiu in Jingkou Town, and defeated Huan Xuan the following year. Huan Xuan retreated to Jiangling (now Hubei) with Andy, and was defeated by the northern government soldiers under the command of Liu Yi. Andy returned to Jiankang for restoration. In order to quell the chaos, Emperor Wu of Song added Shi Zhong, and entered the No.1 car to ride the general and the Kaifu instrument with the third division, and the town of Jingkou. In the fourth year of Yixi's reign (408), he entered Beijing to assist the government and monopolized the power of North Korea.

The Xianbei Murong Nanyan regime, which occupied Shandong, invaded the border of the Eastern Jin Dynasty many times when it was in decline and chaos. In February of the fifth year of Yixi, Murong Chao plundered the Huai River, and Emperor Wu of Song led an army to the Northern Expedition. In April, the rate of water army from Jiankang north, along the Huaihe River, the greater Xi 'an (now Mulingguan, Yishui North, Shandong Province), the following year, the capital of Southern Yan, Optics Valley (now Yidu Northwest, Shandong Province), recovered Qingzhou and Yanzhou, captured Murong Chao alive and beheaded Jiankang. In seven years, Lu Xun was suppressed. In the past eight years, Liu Yi, who "can't survive, will eventually become a heresy", Zhuge Changmin and Sima Xiuzhi, the imperial clan of the Jin Dynasty, who may pose a threat, were eliminated, the alien forces were eliminated and the rear area was consolidated. In nine years, Qiao Zongxi attacked and Bashu recovered. In the twelfth year, Yao Xing, the master of the late Qin Dynasty, died of illness, and his son Yao and his brother killed each other, disturbing Guanzhong. Emperor Wu of song took the opportunity to lead the army in four ways to explore the late Qin dynasty and tackle key problems. Crossing the Yellow River, defeating the northern Wei army, entering Luoyang and Tongguan the following year. He ordered the general to take Chang 'an directly, and Yao Hong surrendered. Later, Qin died. The recovery of Chang 'an by the Jin Army is a longing of the Han people who have been ruled by ethnic minorities for a hundred years. At this time, due to the death of Liu, the minister who stayed in the imperial court, Emperor Wu of the Han Dynasty was afraid that the regime would fall into the hands of others, so he left his second son in Chang 'an, assisted by and hurried back to Jiankang. Chang 'an left-behind troops fought internally, and Helian Bobo, the master of Xia Dynasty, seized Guanzhong. Although Liu Yizhen was forced to withdraw from Chang 'an, from the east of Tongguan to the south of the Yellow River to Qingzhou, it was the territory of the Southern Dynasties, and the Jianghuai basin was guaranteed, which Zu Ti, Huan Wen, Xie 'an and others failed to achieve for nearly a hundred years.

After Liu Yuna went back, he also appointed Song Gongjiu as Prime Minister Xi. When Andy died, Emperor Gong acceded to the throne, recruited him as a supplement and made him king of the Song Dynasty. In the second year of Emperor Gongdi Yuanxi (420), Song Wudi proclaimed himself Jin, with the title of Song, and changed to Yuan Yongchu. Before and after he proclaimed himself emperor, he paid attention to frugality, rectified the chaos in the Eastern Jin Dynasty, suppressed the strongmen, killed Diao Kui in Jingkou, and distributed Diao's vast land and a large amount of family wealth to the poor. Later, he killed Yu Liang, an anonymous Yuyao ethnic group, in an attempt to limit the merger. Abolish part of the wasteland to relieve the people, prohibit powerful people from closing mountains, continue to break ground according to boundaries, and let the northern overseas Chinese who have settled in Jiangnan pay taxes and serve, thus streamlining overseas Chinese counties. He also reduced the punishment, personally tried the lawsuit, promoted the school, and tried the scholars in various counties. The agricultural production in the south of the Yangtze River was restored and developed, which laid the foundation for the situation of "self-protection and multi-benefit, surplus grain living in mu" in the Yuan-Jia period (424 ~ 453).
