What do you mean by civil war?

The two fights between north and south refer to the stars.

In ancient astronomy in China, the stars in the sky correspond to human beings. The noblest person in the world is the emperor, and the emperor in the sky is the purple star, that is, the Polaris, which dominates the stars in the sky in the purple wall. Wei Zi is the leader and representative of all the stars. According to Wei Zimen's star division method, all the stars are divided into three systems: Beidou, Nandou and Zhongtian. The battle of Wei Zimen means the battle between the north and the south.

The so-called Wei Zi Graffiti is a skill that transforms the date of birth into the arrangement of stars in the north and south. Headed by Wei Zi, it calculates a person's good or bad luck and fate according to a specific method. Wei Zi Dou Shu, or Wei Zi Dou Shu for short, is called the head of the Three Gods by numerology circles.
