Feng Hong
The Goguryeo kingdom was a powerful and influential state in northern Korea and parts of northeastern China at the beginning of the Sixteen Kingdoms period. Goguryeo was attacked by the Murong Xianbei numerous times, and in 342 Prince Murong Huang of Former Yan captured the Goguryeo capital Hwando (Wandu in Chinese). Under the powerful and dynamic leadership of feudal kings, Goguryeo during the reign of Gwanggaeto the Great successfully invaded the kingdoms of Baekje, Silla, and Dongbuyeo. Riding its success, Goguryeo campaigned against the Later Yan, obtaining the Liao River region. King Murong Xi of Later Yan twice launched retaliatory attacks to reclaim the Liao River watershed territory, but was only partially successful. At Northern Yan's destruction by the Northern Wei, Yan king Feng Hong fled to Goguryeo to seek asylum. Although granted asylum, Hong was said to have acted as if he was still king, issuing orders and demanding respect, and was executed by King Jangsu of Goguryeo.
