China is a great country with the largest population in the world. In order to solve the population problem, our government decides to implemented one-child policy. When it is carried out for some time, many people not only see its advantages but also disadvantages. Thus, people argue that o-child policy should be put into effect. In my opinion, o-child policy should be carried out. First of all, o-child policy is the gift for some only child. For some families, maybe the parents are only child and they also can have only child. Put aside the loneliness of their child, when their child grows up and they grow older, their child marry with an only child girl accidentally, the burden on their child and his wife is unimaginable heavy. Their child and his wife have to take care of o old couples. Usually, a young couple looking after an old couple is a little difficult; if the pressure increasing ice, how can they stand it. But if their parents have o children, they can share the burden of taking care of their parents. It would be much better. Secondly, o-child policy can guarantee the number of Chinese population. As the widely spread of one-child policy, some people have changed their conception about giving birth. If they firmly believe one-child policy, there will be more and more the dink. After several decades, our country will famous for lack of population. In conclusion, one-child policy has out of date. And tow-child policy is needed and necessary. It can solve the problem of nowadays and the future. 　　he constructed a court in the back yard for him to practice on, and from then on mike has been playing the game and playing it well. he went on to play at north carolina, in his freshman year, and in his junior year he was drafted by the bull's
