From the time of entering elementary school (6-7 years old) until the beginning of puberty (12 years old for females and 13 years old for males) is called the school age period (equivalent to elementary school age). During this period, the physical growth of children is still steadily increasing, and the development of organs other than the reproductive system is close to the adult level by the end of this period. The morphology of the brain is basically the same as that of an adult, and the development of intelligence is more mature than before, with increased control, understanding, analysis and synthesis ability, making it an important period for growing knowledge and receiving cultural and scientific education. This period some children will appear early love phenomenon, early love is a bad combination of bad subjective and objective factors. The purpose of diagnosis is to treat, how to prevent and stop early love? 1, strengthen discipline education, prevention before it is too late: the task of students is to study, not allowed to fall in love. To create public opinion and monitor each other. To catch the first signs, practice shows that early love, although at first often can not suppress the emotions of love, but eventually most of the persuasion of teachers and supervisors to ease, or their own in practice hit a wall, after the frustration can discontinue early love relationship. Because early love is mostly out of curiosity or rebelliousness, without much emotional foundation, so discontinuing early love does not mean “leaving trauma”. For the early love between them and the social youth, because the social youth have life experience, the human world is also rich, and has the economic conditions, more difficult, the family and school should pay special attention to prevent and properly handle. 2. Education on ideals and outlook on life: Ideals are the image of future pursuits and aspirations; outlook on life is the view of the value of life. It is a good time to educate them as their outlook on life is forming and their ideals are being established during their adolescence. Once they realize the value of life and the goal they are striving for, they will devote all their energy to learning culture and scientific knowledge and reserve the power of life. At this time, even if they have the stupidity of sexual consciousness, they can restrain it. A high school student wrote in his essay, “(received a love note) a week has passed, I am dizzy every day, like a lost soul …… love, we are justified to get, because we are still very young. But there are many things waiting for us to do. After the excitement and restlessness, if bright and dark youth, what we need is mature thinking, rich experience, the completion of an inner edifice of faith and ideals.” 3. Education on sexual knowledge and social morality: Education on sexual knowledge should be combined with education on social morality. First of all, should be based on different age stages, focus on the content of education. 12 ~ 16 years old, education about the physiological and health knowledge of puberty, so that they have a correct understanding of sexual development; 16 ~ 18 years old, can briefly introduce some sexual knowledge, so that they correctly treat the opposite sex and love; 18 years old and above, can guide them to seriously consider the future of marriage and family issues. Secondly, the induction of sexual awareness and education on sexual morality. It is impossible to strictly check and stop the bad factors of the society, we should face the reality and induce them to improve their adaptability and immunity, and enhance their resistance and conscious inhibition of sexual triggers; realize that people are not animals and must accept the constraints of social ethics, morality and law.
