In the later period of Emperor Wu of Liang, political corruption, official corruption, social atmosphere was flashy and extravagant, and the people's displacement and exile were extremely serious. Emperor Wu of Liang created a decadent and decadent ruling clique centered on the imperial family and the family clan. This group, tolerated by the emperor, enjoyed various privileges. However, the people were displaced under their exploitation, which was the most fundamental reason for the turmoil and demise of the Liang Dynasty in the last years. In the last years of Emperor Wu's reign, Emperor Liangwu was not only full of mistakes in internal affairs, but also made many foolish things in handling relations with Northern Wei externally, especially on the issue of accepting Hou Jing. After the Northern Wei Split into Eastern and Western Wei, the two sides fought for many years, and the attack on the south tended to be flattened; and the Liang Dynasty also began to decline, and large-scale military operations against the Northern Dynasty stopped. However, Emperor Wu of Liang always wanted to find an opportunity to attack the Northern Dynasty. In the second year of Zhongda Tong (547), the Eastern Wei general Hou Jing was forced by Gao Huan's son Gao Cheng to surrender to Liang. Emperor Wu of Liang gladly accepted, and thought that the time had come for the Northern Expedition.
The contradiction between Hou Jing and Gao Cheng was aroused, so he defected to other countries. Emperor Wu of Liang's acceptance of Hou Jing was considered to expand Liang's territory. However, he lacked caution in dealing with the matter and did not fully estimate Hou Jing's actual situation, resulting in a very serious mistake. After Hou Jing surrendered to Liang, Emperor Wu of Liang sent his nephew Xiao Yuanming to attack Gucheng in the winter of the seventh year of Datong (541), hoping to echo Hou Jing. Xiao Yuanming was a man who could not fight at all, and as a result, the Liang army was defeated by Gao Cheng of Eastern Wei, Xiao Yuanming and several important generals Hu Guisun and Zhao Bochao were captured by Eastern Wei, and Liang killed tens of thousands of soldiers. Emperor Wu of Liang heard the battle report that Xiao Yuanming had been captured in the front, and had to start making peace with Eastern Wei. In the spring of the eighth year of Datong (542), Hou Jing was defeated by Eastern Wei and fled to Shouyang in the Liang Dynasty. In this battle, the weakness and incompetence of the Liang Dynasty gave Hou Jing a great stimulus. Gao Cheng saw that he was eager to make peace, and proposed to exchange Hou Jing for Xiao Yuanming. Emperor Wu of Liang did not consider the consequences and agreed with his mouth. When Hou Jing knew that Emperor Wu of Liang would exchange him for Xiao Yuanming, he raised an army at Shouyang to attack Jiankang, causing an unprecedented upheaval at the end of Liang. History called this turmoil the HouJing Rebellion, also known as the "Difficulty of Taiqing".
In October of the second year of the Taiqing Dynasty (548), Hou Jing attacked Yu Prefecture (谯州, in modern Chu County, Anhui), and Emperor Wu of Liang ordered his nephew Xiao Zhengde to defend the Yangtze River. Xiao Zhengde dispatched dozens of large ships, falsely claimed to have intercepted them, and secretly received Hou Jing to cross the river. Emperor Wu of Liang ordered his crown prince Xiao Gang to plan defenses, and Xiao Gang gave Xiao Zhengde the task of defending Xuanyang Gate. Xiao Zhengde led the crowd at Zhang Jianqiao to welcome Hou Jing into the Yiyang Gate. In November, Xiao Zhengde proclaimed himself emperor and made Hou Jing his chancellor. Hou Jing's army attacked Taicheng (Miyagi) and surrounded taicheng. In the third year of the Taiqing Dynasty (549), Hou Jing invaded Taicheng and imprisoned Emperor Wu of Liang at the Wende Hall in Taicheng. Emperor Wu of Liang was so angry that his diet was cut off, and he was starved to death at the Wende Palace at the age of eighty-six.
Hou Jing's rebellion dealt a devastating blow to the Southern Dynasty Scholars. More than half of the city starved to death. Jiankang, which had been prosperous for many years, was almost gone after this war. In the third year of the Taiqing Dynasty (549), Hou Jing and Xiao Zhengde had a conflict. Xiao Zhengde secretly summoned Fan, the Prince of Junyang, and asked him to lead an army to attack Hou Jing. Hou Jing received the news, killed Xiao Zhengde, and made The Crown Prince Xiao Gang emperor for Emperor Jianwen of Liang. In the second year of Dabao (551), Hou Jing deposed Emperor Jianwen and made Xiao Dong the Prince of Yuzhang emperor. Less than three months later, Xiao Dong was deposed and locked in a secret room. This time, he simply became the emperor himself and was called the Emperor of Han.
In 554, the ninth day of October in the third year of the Southern Dynasty Liang Chengsheng, the Western Wei zhu state Yu Jin and Yuwen Hu, and the general Yang Zhong led 50,000 troops into Jiangling. On the second day of the first lunar month of the following year, Gangneung fell. Wang Shengdi was not rescued in time, and Emperor Yuan of Liang was immediately killed at the age of forty-seven. The courtiers and the strong among the people were plundered, and Chen Baxian's son Chen Chang and nephew Chen Haoben were on duty in the palace of Emperor Yuan of Liang, and this time they were also taken captive to Chang'an. Gangneung was almost a pile of rubble. Emperor Liang's nephew Xiao Qi (萧詧), the son of The Former Crown Prince Zhaoming, was raised as a puppet emperor under the supervision of the Western Wei garrison and established a small kingdom of "Later Liang" within three hundred miles.
Emperor Wenxuan of Northern Qi (Eastern Wei had been replaced by Northern Qi) Emperor Wenxuan Gao Yang was not willing to accept the expansion of Western Wei's power to the south, and also wanted to take advantage of the defeat of the Liang state, and came to divide it up, sending his brother Gao Zhuo, the King of Shangdang, to lead an army south to escort Xiao Yuanming, the Marquis of Zhenyang, who had been captured by Eastern Wei, to ascend the throne of the Liang state. Chen Baxian insisted on not accepting Xiao Yuanming, but Wang Gradually weakened with Pei Zhi's defeat and surrendered to northern Qi pressure, and in May, Xiao Yuanming entered Jiankang, that is, the emperor's throne, changed Yuan Tiancheng, and established Liang as the crown prince. Chen Baxian struggled bitterly to no avail, hated wang monks for defending unilaterally, and abolished the establishment without authorization, and in September, Xu Du and Hou An both marched with Chen Baxian on land and water and raided Stone City. The monk was caught off guard, and was soon captured and immediately hanged. Faced with such a situation, Xiao Yuanming had to abdicate. In October, king Liang, the emperor, was renamed Yuan Shaotai as Emperor Jing of Liang. Chen Baxian appointed himself Shang Shu Ling, governor of various Chinese and foreign militaries, che cavalry general, Yang, and Southern Xu Erzhou. Chen Baxian, the governor of Guangzhou, took advantage of the situation to develop and expand his own forces, and after nearly a decade of war, Chen Baxian basically controlled the lower Reaches of the Yangtze River. Seeing that the time was ripe, he deposed the Liang Jing emperor Xiao Fangzhi in the second year of Taiping (557), proclaimed himself emperor in Jiankang, and established the Chen Dynasty. Since then, the Liang Dynasty has fallen, and it has lasted for a total of four emperors and fifty-five years.
