Liu Can
Liu Can was Liu Cong's son by his first wife, Empress Huyan, but was not created crown prince when Liu Cong became emperor in 310 after seizing the throne from his brother Liu He (after Liu He had tried to have him and the other brothers killed and successfully killed two), because Liu Cong had promised to and did make his brother Liu Ai (劉乂), the son of his father Liu Yuan's second wife Empress Dan, crown prince. Liu Can was, however, created the Prince of He'nei and given a substantial military command. He was one of Han Zhao's major generals early in Liu Cong's reign, along with his father's cousin Liu Yao the Prince of Shi'an, Wang Mi (王彌), and Shi Le. He appeared to be a competent general, although not as capable as Liu Yao or Shi Le, and he had mild successes in battle, although his campaigns were largely inconclusive. His mother Empress Huyan died in 312.
