What do you mean by "a cow outside the column" and "a cow inside the column"?

Cattle outside the fence: refers to cattle that are free from the fence. Just like the bird outside the cage, you can think of many similar words. If the fence is regarded as a circle, it can be extended to people outside the circle.

Cattle in the column; Geomantic terms in ancient folk customs. Refers to people born in ugly years. From the theory of the intersection of three students, it is a kind of fortune telling. The life of the cow in the column is sixty ugly years, which corresponds to the ugly year. That is, people born in their own ugly years are all "cows in the column."
