It is reasonable and legal to prohibit boys from entering the women's bathroom. The physiological differences between the two sexes should not and cannot be eliminated. In the bathroom, all kinds of physiological differences are exposed. As a normal individual, being stared at by the opposite sex will naturally cause discomfort, even if the opposite sex is a child. Parents take boys into the women's bathroom, which ignores the psychological feelings of all women present, is a prominent manifestation of selfishness and an invasion of others' privacy. Because children have gender awareness as early as three or four years old, age cannot be used as a "shield" for mothers to escape accusations.

Public bathing belongs to public places and naturally has its own public order. Based on the above considerations of privacy protection, it is a long-standing rule for hotels to set up separate toilets for men and women. The bathroom has set a height standard for children of the opposite sex who are allowed to enter, which is already a humanitarian adaptation to special circumstances and should not be broken because of various reasons of women. Even if the child is young and tall, it is impossible to "knock down" the universally recognized order rules. Women obviously have better choices than quarreling, such as letting their father accompany them, booking a single room or going home to take a shower.

Secondly, for children who are initially establishing gender awareness, taking children into the opposite sex bathroom is not only a disrespect for others, but also a disrespect for the children themselves. Kindergarten children have entered the stage of remembering things. When they grow up, they will inevitably feel ashamed and embarrassed when they recall the experience of taking a bath in the opposite sex bathroom.

According to article 1 198 of China's Civil Law, "the operators, managers or organizers of mass activities in hotels, shopping malls, banks, stations, airports, stadiums, entertainment places and other places of business shall bear tort liability if they fail to fulfill their security obligations and cause damage to others." Hao believes that baths, swimming pools, gyms and other similar public places should provide security for customers and ensure their personal and property safety and personal privacy. For entrances that need to be entered by gender, gender tips and signs should be given, and service personnel should manage them accordingly.
