After retiring on April 30, South Korean actor Hyun Bin made his first return as a historical film "inverse scale," in which he played the young king Zhengzu of the North Korean period. Up to now, although there are many TV dramas or movies with Wang as the theme, Xuanbin will embody the unusual king Zhengzu with a more tenacious and magnificent appearance through the film Anti-scale. The title of the film "inverse scale" refers to an untouchable scale on the dragon, which emits infinite dragon power as soon as it is touched, that is, the anger of the monarch. It implicitly expresses the state of mind of Zhengzu who needs to keep the royal power in the contest between the old theory and the young theory of the two schools.
