Murong Hui
Daifang Commandery was inherited by the Jin dynasty. Due to the bitter civil War of the Eight Princes, Jin became unable to control the Korean peninsula at the beginning of the 4th century. Zhang Tong (張統) broke away from Jin in Lelang and Daifang. After Luoyang, the capital of Jin, was occupied by the Xiongnu in 311, he went for help to Murong Hui, a Xianbei warlord, with his subjects in 314. Goguryeo under King Micheon annexed Lelang and Daifang soon after that.
