Brief introduction of ceiling ruler

There is a cloud in The Book of Tao Te Ching Helping the Gods: Except for ominous peach branches, the ancients died of peach branches, so later generations used them as ghosts. Today, Governor Peng is one of them. Long scale. Rulers are made of mahogany or iron. The ceiling rulers are mostly quadrangular, and the six sides are engraved with Twenty-eight Nights, Sun and Moon, Purple Taboo (the name of China Emperor Wei Zi), Ceiling Taboo (the name of Tian Pengyuan Shuai), Six Stars in the South and the Big Dipper (namely the King of the Southern Star and the King of the Big Dipper). In the eastern Jin dynasty's mythical novel "Searching for the Gods", the viewpoint that "the southern bucket is reborn and the Beidou is dead again" was put forward. Waving a ruler means respectfully inviting Tian Pengyuan Shuai to the altar to exorcise evil spirits.
