What does Tigress mean by going downhill?

In civil marriage, there is a taboo that the woman's zodiac is a tiger. This taboo custom is likely to come directly from the people's "fear of tigers" psychology. Is to treat a woman who belongs to a tiger as a "tiger *" that can really hurt people and kill people. Because tigers always come out to eat people at night, they are especially jealous of tiger girls born at night. Moreover, female tigers born at night are further divided into "mountain tigers" and-pokeweed roots. Those born in the first half of the night are called "mountain tigers", and those born in the second half of the night are called "Shanglugen"
