In 316 AD, the Former Zhao Xiongnu army attacked Chang'an, and the Western Jin Dynasty fell. The following year, Sima Rui proclaimed himself emperor at Jiankang, in honor of Emperor Yuan of Jin. The Eastern Jin Dynasty could be established thanks to the support of Wang Dao, Wang Dun and other families in the north and south. Before Sima Rui claimed to be emperor, he still obeyed Wang Dao's words and other words. Sima Rui claimed to be empress dowager, intending to strengthen the centralization of power and weaken the power of the magnates, but the result intensified the contradictions with the magnates, resulting in Wang Dun's mutiny. Sima Rui died of fear during the rebellion of Wang Dun. In 322, sima shao the crown prince succeeded to the throne as emperor of Jinming. In the Eastern Jin Dynasty, only the Jin Ming Emperor could do something. Emperor Ming of Jin reused xianchen and quickly quelled Wang Dun's rebellion, but not long after, in 325 AD, the 27-year-old Sima Shao died of illness and was succeeded by the 5-year-old Sima Yan. Before Sima Shao's death, he handed over the power of auxiliary government to his uncle Yu Liang. Sima Shao arranged the affairs of the aftermath in this way, obviously in order to use the power of foreign relatives to suppress the power of Wang Dao and other clans, so as to achieve the purpose of balancing the regime. However, judging from what happened later, Yu Liang's talent was not good, and it could even be said that he was more like an irresponsible "bear child".
When Wang Dao came to power, he implemented the policy of the Yourong family clan, which led to political corruption in the early years of the Eastern Jin Dynasty, corruption of officials, mergers and acquisitions of powerful and powerful, and increasingly acute class contradictions. Yu Liang governed and did the opposite. He advocated the rule of law, advocated strengthening the centralization of power, and weakening local forces, so he was opposed by the family clan. What is particularly serious is that the contradiction between Yu Liang and local forces is constantly intensifying. Li Yang Nei Shi Sujun proudly supported the strong soldiers and did not put Yu Liang in his eyes. He privately recruited outlaws in Liyang to expand his army. To this end, Yu Liang sent Wen Yao to serve as the Assassin of Jiangzhou, the governor of Jiangzhou, the military of Jiangzhou, the town of Wuchang, and the monitoring of the movements of the Jingzhou side. He then deployed fortifications to build Stone Castle, strengthen the capital's garrison, and prevent sudden events.
Chaos first occurred from the capital. After Sima Zong stepped down from a prominent position as a general of the Left Guard, he harbored a grudge and tried to get rid of Yu Liang. Yu Liang took the lead and killed Sima Zong and his accomplices on the charge of treason. One of Sima Zong's subordinates, Bian Xian, fled to Liyang to defect to Su Jun, and Yu Liang ordered Su Jun to hand over the man, but Su Jun refused to comply. Yu Liang took this opportunity to transfer Su Jun into the dynasty in order to seize Su Jun's military power. Su Jun did not comply several times. In the end, he had no choice but to rebel with Zu Yue.
In October of the second year of Xianhe (327 AD), Su Jun raised an army. Jiangzhou Assassin Shi Wenyu heard the report and asked to lead the army to rescue, but the team had not yet set off, Yu Liang actually wrote to stop it, saying: "My worries about the western frontier exceed Li Yang, and I must not cross the thunder pool one step at a time." Yu Liang did not allow Wen Yu to cross the East direction of Lei Chi, and he was relieved of Tao Kan. At the same time, the Sanwu generals requested to send troops to defend Jiankang, but Yu Liang even refused.
The rebels took the initiative to attack, but Yu Liang took a passive defense. Someone suggested to Wang Dao: "We should send troops to quickly cut off Fuling and hold on to the ferry ports such as Dangli in the north of the jiangsu province, and we can completely defeat them in the case of the enemy and the masses." If the enemy does not arrive, we can press into Liyang; if we do not attack, the enemy will attack first. This is a precursor, and the opportunity must not be lost! Yu Liang, however, believed that Jiankang was impenetrable, and Su Jun would never dare to directly attack Jiankang. However, while Yu Liang was still self-absorbed, Su Jun's generals Han Huang and Zhang Jian attacked the Eastern Jin Dynasty's aunt who had hoarded a lot of salt and rice, and directly pounded Cihu Lake. After Yu Liang got the report, he cried bitterly. In these two columns alone, it can be seen that Yu Liang has no talent in ruling the country and ruling the army.
Later, Su Jun's army attacked Jiankang City, yu Liang knew that the general situation was gone, and he could not care about the sister of the empress dowager and the emperor's little nephew, so he hurriedly said to Zhongya, "The matter here will be up to you." ”
When Chung Ya saw that Yu Liang was about to abandon the mess he had created with his own hands, he fled in anger and said angrily: "The beam is broken, and the rafters collapse, whose responsibility is this?" ”
Yu Liang had no choice but to say cheekily: "There is no need to say more about today's events, you are waiting for me to fight back to Jiankang." Then, hurriedly ran away with his brother Yu Yi, Yu Tiao, and Yu Yi.
Yu Liang and the others had just boarded a small boat on the riverside, and the enemy army also caught up with them, and the two sides fought a scuffle. Yu Liang opened his bow left and right, and in a hurry, he accidentally shot the helmsman of his ship to death, and the people on the ship were momentarily frightened and panicked to jump ship and escape. Yu Liang calmed down, he did not move, hating himself and saying, "How can these hands be used to kill thieves!" The mood of the crowd settled down and they finally escaped. Probably Yu Liang said, "How can these hands be used to kill thieves!" At that time, he also woke up to the fact that he was not the material for managing the country at all.
