Bins(殯) refer to coffins temporarily put in a shallow pit over the steps in west after Daeryeom. Yegi says the Bin ceremony starts at different points according to social status. It starts seven, five, and three days after the passing of emperors, feudal lords, and Daebu·Sa·Seoin, respectively. It is estimated that the Bin ceremony for King Muryeong started five days after his passing since he was a feudal lord. As for the expression of Baekje Daebin, the word Daebin appeared in Manyeopjib two times. It can be interpreted as a western building in Baekje. In Nihon Shoki, a funeral parlor was called a building name or Namjeong when it was a place name or inside a palace. It is thus estimated that Gungbuk means a separate building outside a palace. That is, it is likely that they used the term Baekje Daebin to mark only a direction without the elucidation of a certain place. Since people understood that a funeral parlor should be established in west in Baekje those days, his funeral parlor was established in Mt. Jeongji in west of Gong Mountain Fortress. The Bin period was of huge importance since it would witness the new king ascending the throne, claiming his legitimacy as a successor, and having his authority as a king recognized officially. Accepting the culture of Southern Dynasties in China, King Seong of Baekje ascended the throne on the same day and supervised the funeral rites of King Muryeong. The study examined the ways that they paid respects to the deceased those days and found that envoys dispatched to the funeral ceremony would deliver a eulogy in the western steps and wail after the eulogy. Mourners would cry, sing, or dance.
