刘粲
Her clan, the Huyans, were probably a noble clan of Xiongnu, as a large number of Han Zhao officials were named Huyan. She was created empress in 310 after Liu Cong seized the throne from his brother Liu He (after Liu He had tried to have him and the other brothers killed and successfully killed two). She was the cousin of the first empress of Liu Cong's father Liu Yuan. She bore Liu Cong at least one son -- Liu Can, whom Liu Cong created the Prince of He'nei and commissioned as a major general. However, he did not create Liu Can crown prince because he had promised to make Liu Ai (劉乂), son of Liu Yuan's second wife Empress Dan, who had yielded the throne to him after Liu He's death, crown prince. (He also had an affair with Liu Ai's mother Empress Dan, and this affair was part of the reason.)
