China's Liang shu gives his surname as Yeo and personal name as Yung, and states that he restored Baekje into a strong nation.

He was called Semakishi (嶋君) and King Shima (斯麻王) in Japanese records because he was born in an island.

In reply, the Liang emperor bestowed various titles on him, including "Great General Tranquilizing the East (寧東大將軍)" and "King of Baekje".

In 1971, King Muryeong's tomb was excavated in Songsan-ri, Gongju, South Korea, where he was buried with his queen.In 2001, Japan's emperor Akihito told reporters "I, on my part, feel a certain kinship with Korea, given that it is recorded in the Chronicles of Japan that the mother of Emperor Kanmu was one of the descendant of King Muryong of Baekje."

[3] According to the Shoku Nihongi, Emperor Kanmu's mother, Takano no Niigasa (720 – 790) is a descendant of Prince Junda, son of Muryeong, who died in Japan in 513 (Nihon Shoki Chapter 17).
