1) Gender imbalance: China has a long-standing preference for male children, which has led to a severe gender imbalance in the country. This imbalance has resulted in a shortage of women, making them more vulnerable to trafficking and abduction.
2) One-child policy: China's one-child policy, which was implemented from 1979 to 2015, also contributed to the Missing Girl Phenomena. Under this policy, many families were forced to give up their female children in order to comply with the government's regulations.
3) Weak law enforcement: China's law enforcement system has been criticized for being weak and inefficient in dealing with crimes against women and children. This has made it easier for traffickers and kidnappers to operate without fear of punishment.
4) Poverty: Poverty is another factor that contributes to the Missing Girl Phenomena. Many families in rural areas are struggling to make ends meet, and they may be more likely to sell or give up their female children in order to generate income.
