He was the younger brother of Lady Wu, the wife of Sun Jian - a warlord of the southern kingdom of Wu. Due to this fact, Wu Jing fought many battles alongside Sun Jian. After Sun Jian died and his son Sun Ce succeeded, Wu Jing turned over to the forces of Yuan Shu. However, after Sun Ce beat Liu Yao and Yuan Shu assumed the title of emperor, Wu Jing rejoined Wu under Sun Ce. The Three Kingdoms period was one of the bloodiest in Chinese history. A population census during the late Eastern Han Dynasty reported a population of approximately 50 million, while a population census during the early Western Jin Dynasty (after Jin re-unified China) reported a population of approximately 16 million. However, the Jin dynasty''s census was far less complete than the Han census, so these figures are in question. Even after taking into account the possible inaccuracies of these census reports, the fact a large percentage of the population was wiped out during this period of constant war is beyond doubt.
