In May of the seventh year of Huang Wu (228), Sun Quan ordered Zhou Fu, the prefect of Poyang, to break off and fall, pretending to be a traitor Wu Dong and seducing Cao Xiu, the general of Wei. The Battle of Shi Ting broke out. In autumn and August, Sun Quan went to Wankou and sent Lu Xun, the general of the Western Expedition, to lead Huan Zhu and Quan Cong to defeat Cao Xiu in Shi Ting.
In the first year of Huanglong (229), Sun Quan, who ruled Jiangdong for 30 years, officially proclaimed himself emperor in the southern suburbs and changed his name to Huanglong. In April, Sun Quan granted amnesty and went to the southern suburbs to worship heaven, that is, acceded to the throne. Zhuge Liang sent Wei Yanma to Soochow to congratulate Sun Quan on his accession to the throne. Three months later, Sun Quan moved the capital from Wuchang to Jianye.
His father Sun Jian was named Emperor Wu Lie, and his mother Wu and his eldest brother Sun Ce were named King Huan of Changsha. Sun Deng, the prince of Wu, was appointed as the Crown Prince. Generals and officials were promoted and rewarded. In June, Shu sent people to celebrate Sun Quan's accession to the throne. Sun Quan reciprocated by acknowledging the existence of the emperors of the East and the West, and negotiated with the envoys of Shu and Han to divide the world equally.
Extended data:
Since Sun Quan succeeded as the governor and weak crown of Jiangnan regime, he recruited foreign talents to train his subordinates, used appeasement strategy to win over Jiangnan tycoons who did not obey the Sun Shi family, integrated the internal resistance to external pressure from scratch, and consolidated the position of Sun regime in Jiangnan. On the other hand, he put down the Yangyue Rebellion, carried out Qiang Bing's policy of absorbing the old, the young and the weak, and provided the backward Shanyue people with the study of China culture.
Sun Quan in the vassal period did not belong to any party, and there was no so-called political slogan of rejuvenating the Han Dynasty and destroying it. Therefore, we can judge which side is of use value according to the development of the current situation and carry out the strategy of joint free diplomacy in order to obtain our own interests. As the emperor who started the foundation, Sun Quan, with his outstanding political wisdom and strategic judgment, understood the way of strategic alliance and finally created a hegemon.
After Battle of Red Cliffs, he strengthened his control over Jiangdong, extended six counties in Jiangdong to three states of Yang, Jing and Jiao, actively exploited the barren land in the south, and firmly controlled the southeast of China.
