The idea of seizing Jing Province in the Longzhong Plan was a flawed concept because Sun Quan would never accept Liu Bei in control of this critical area, crucial for the security of his base in Jiangdong.
The tribe became powerful during the Eastern Han and the period of the end of the Eastern Han, but was absorbed into Han culture after the Sun family established a strong local government on Jiangdong.
Most devastating of the departures and defections - both to Yuan Shu personally and to the strength of his forces - was that of Sun Ce, who had recently conquered most of the Jiangdong territory under Yuan's banner.
Between 194 and 199, the warlord Sun Ce embarked on a series of conquests in Jiangdong and seized control of most of the territories in the region.
