What do you mean by tattooing left green dragon and right white tiger?

Stars are an important theoretical basis for the ancients to infer the good and bad luck of a day. After long-term observation, the ancients chose 28 stars near the equator of the ecliptic as coordinates. Because they revolve around the sun, the moon and the five stars, they are very similar to the places where the sun, the moon and the five stars live, so they are called twenty-eight lodgings. The ancients also divided twenty-eight lodgings into four palaces, east, south, west and north, with seven lodgings in each palace. Each palace imagines its seven dwellings as an animal, and considers it as "the four souls of heaven and square". The seven nights of the East Palace Black Dragon are: Jiao, Kang, Bian, Fang, Xin, Wei and Ji; The seven nights that Nangong Suzaku belongs to are: well, ghost, willow, star, Zhang, wing and bird; The seven nights that Xigong White Tiger belongs to are: Kui, Lou, Stomach, Ang, Bi, Gou and Shen; Gong Bei Xuanwu (tortoise and snake) belongs to seven nights: fighting, ox, female, emptiness, danger, house and wall.

Left Qinglong right white tiger, former Suzaku back to Xuanwu. There is death in the middle. These four planet guardians have no practical significance. Is it because I watched too many Stephen Chow movies, "Left Qinglong, Right White Tiger, Old Cow at the waist, Leading in the chest?" People stop killing Buddha, stop killing Buddha.
