A girl as young as 4 years old has her period, a boy less than 5 years old starts to grow a beard …… These mind-boggling things are happening more and more to children in China. According to statistics, the incidence of premature sexual maturity in Chinese children has reached 1%, that is, 1 in 100 children have premature sexual maturity. Recently, there is worrying news from major hospitals in Shanghai that the sexual development of children in Shanghai is now significantly early, and their mental age is generally not keeping up with their physical age, and more and more children are using language that adults can hardly speak about sexual problems. According to the analysis of pediatric medical experts, there are many reasons for the early sexual development of children, but the stimulation of sexual content in the media, such as television and video, should not be ignored. Experts especially stressed that since the 1990s, due to the popularity of film and television media, the audio-visual stimulation formed by bad romance and sex-related TV dramas has become an emerging killer leading to early sexual development in children. According to statistics, more than 95% of precocious sexual maturity comes from environmental stimulation, of which the influence of language and cultural environment pollution cannot be ignored, and too many passionate scenes in TV and movie programs are the direct cause of early development of children. Children’s early psychosexual maturity is first of all caused by the social environment. It should be said that today’s mass media, especially the content of the film and television media, the proportion of content involving sex is quite high. Including some serious subjects of drama, in which are deliberately to add some love scenes. This kind of film and television topics follow the shadow of the child, their psychological impact can be imagined. Some newspapers and magazines are becoming more and more eager to speculate on sex-related topics, and the private lives and sexy photos of some singers and stars are moved to the pages of newspapers and magazines in the name of health guidance, and there are many columns in the paper media speculating on sex-related content. As society becomes more open, there has been a dramatic increase in sexual innuendo in children’s everyday environments. The proliferation of pornographic networks is a prominent phenomenon, and the proliferation of massage parlors, cabarets, and scantily clad “ladies” roaming around is also having a dramatic psychological impact on children. As a group with poor social discernment, minors are often defenseless against the erosion of bad culture. Since sexual behavior itself has a certain attraction and temptation, it is easy to be absorbed by young children indiscriminately, thus, directly causing the precocious sexual psychology of minors. The impact of precocious sexual maturation induced by psychosexual stimulation on children’s development is being revealed. Professor Lei Pei Yun, an expert in pediatric medicine, points out that children with precocious psychosexuality induce personality and psychological distortions, and the affected children may have low self-esteem, fear and anxiety because they are physically different from their small surrounding partners. Due to the precocious sexual development, the mental age of children generally cannot keep up with their physical age, which can also lead to juvenile delinquency and social maladjustment. Among the social actions to clean up the environment in which minors grow up, it is necessary to ask the media to strengthen self-discipline. However, what must not be overlooked is that adults must control their own words and actions. For it is unthinkable that vulgar adults will produce refined minors.
