Although China solved one of the population problems, it caused another problem without knowing it. As early as 1976, China faced a problem of excessive population. The increase in China's population has brought many problems to the country and people. Some problems come from overcrowding and there is not enough resources (food and work etc) to meet everyone's needs. This is why the Chinese government enacted the "one-child policy law" to prevent over-population. One-child policy is a law motivated by the economic and educational benefits for families that allow families to have one child and comply with the law, and in many cases the law violation
In ancient China, the birth of a boy was always more important than the birth of a girl. A girl in a poor family may be sold as a servant of a wealthy family. However, ancient Chinese children liked it very much. If a family has to give up on a child, that's because they can not afford it.
Most Chinese boys and girls do not go to school. They are working on their parents' farm, weeding and sowing. Even wealthy girls will not go to school, but boys from wealthy families will not go. Boys work very hard at school because it is the only way to gain political power by taking good grades in state exams.
Girls are using social media rather than men and they seem to affect mental health. At the age of 10, 7% of boys are playing, while 10% of girls play 1 hour on social media every day. However, at the age of 15, the disparity is expanding. 43% of girls use more than 1 hour a day against 31% of boys. At the age of 10, the girl reported a lower level of happiness and reported more social and mental difficulties when older than a boy. There is no causal relationship here, but there may be links from other research perspectives. A study by Jean Twenge at the end of last year showed that teenagers who spend more than a few hours a day on social media have a higher risk of depression compared with few people. Here, the connection of girls is stronger than boys. In recent years, the Centers for Disease Control and Prevention keep track of youth depression and suicide increases, and some researchers strongly believe that social media is involved.
