In line with measures to deal with the declining birthrate and tougher penalties for sex crimes, we will strengthen guidance on health and physical education in schools nationwide from this year.In order to conduct more practical sex education than before, both men and women will be naked and introduce a curriculum of ''''high quality'''' health and physical education.Emphasis is placed on lessons that cannot be learned from classroom lectures alone, such as the mechanism of ejaculation, methods of sexual intercourse, and how to use contraceptives (condoms).This video was made mainly to explain this project to teachers, staff, PTA, etc. This is the latest work in the 2019 series, "A shameful work in which men and women are naked and shy, and receive ejaculation and sexual intercourse as sex education as classes"!
