As a result, the director directed the scene that the husband and wife turned against each other on their wedding night, and the woman embarked on the tragedy of suicide.

In the crowd, women without armpit hair and pubic hair are not the only ones. They are afraid of being seen by others, afraid to go to the toilet, afraid to go swimming, worried about whether their sexual function is normal, worried about whether they can have children after marriage, and thus bear a heavy ideological burden. Some parts of the human body surface are particularly sensitive to sexual stimulation of the opposite sex. When stimulated, they can stimulate sexual motivation and get a certain degree of sexual pleasure. These parts of the skin or mucous membrane, known as the human body's "sex sensitive area."

Broadly speaking, all parts that can receive sexual stimulation and cause sexual excitement are sexually sensitive areas. The structure of female external genitalia is more complicated, and there are many folds in skin and mucosa, including sweat glands and sebaceous glands, as well as secretions from vestibular glands, cervix and vagina. Pubic hair is easy to attach to leucorrhea, menstrual blood or the secretion of vulvar sebaceous glands, and the gap between labia majora and labia minora is also easy to hide evil people.
