What does the outer eighth line mean?

Outlining the outer eight lines, surpassing the ancient 360 lines, belongs to another category, that is, it is not serious, and does not belong to industry, agriculture, soldiers, scholars and businessmen. Among the hundreds of industries derived from the three religions and nine streams, one line is theft, and the other eight lines are related, but they are all independent of theft. Because what the Outer Eighth Route does is considered to maintain the balance between heaven and earth, so as to avoid surpassing the existence of a certain person or a certain ethnic group. 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". Counting gold is fortune-telling, ringing horses is a road robbery, and inverted bucket is a grave robbery.
