It seems that the 360 line is divided into the upper eight and the lower eight. What is this?

I haven't heard of it. I've only heard of the outer eight lines.

There are upper nine streams, middle nine streams, lower nine streams and outer eight rows.

"Shangjiuliu" are emperors, sages, hermits, children's immortals, literati, warriors, agriculture, industry and commerce.

The "middle nine streams" are: Juzi, doctor, Xiang Ming, Dan Qing, scholar, Chyi Chin, Taoist and monk.

"Dirty servants" are: masters, servants, scales (scales), matchmakers, pawns, witches, thieves, thieves and prostitutes.

There is also a saying that "nine streams" are also divided into three classes. Shangjiuliu: first prime minister, second minister, third governor, fourth vassal, fifth magistrate, sixth town station, seventh road station, eighth magistrate and ninth mansion. Secondary 96: one doctor, two golds (fortune telling), three floating lines (measuring characters), four pushes (calculating), five Chyi Chin, six calligraphy and painting, seven monks, eight monks, and nine horoscopes (observing stars to determine good or bad luck). Dirty people: Forgotten Eight (running a brothel), Two Tortoise (keeping his wife for prostitution), Three Girls (singing opera), Four Blowers (drummers), Five Big Finances (playing big tricks), Six Small Finances (playing small tricks), Seven Students (hairdressers), Eight Thieves, and Nine Ash Blowers (selling opium). Three religions and nine streams divide people into several classes. In the old society, most of the oppressed were regarded as the lowest class, and their fate was miserable.

There are golden spots, beggars, ringing horses, thieves, fighting, walking mountains, igniting fires and collecting water on the outer eight lines, which are collectively called "five elements and three families". Point gold for fortune-telling, ring horses for blocking roads, inverted bucket for robbing tombs, mountains for deception, fire for law, and water for officials and prostitutes.
