There is a saying in "Mountains and Seas" that a foolish man who is originally wise, in order to maintain the peace of the land and water, will lose his soul and be reincarnated as a fool.
The village guardians of later generations are also known as the Spirit-Suppressing People. They suppress evil spirits from all directions, three evil spirits and five diseases. Although they look silly during the day, once night comes, their souls return to their souls and transform into earth immortals carrying swords to guard the entrance of the village.
