Most of the Chinese people think that a family with one child is better than those with more children. For one thing, many people will try their best to achieve career success and have little time to care about their children; for another, if they only raise one child they can afford better education for the child.
But there are also some negative views about the one-child family. They think it is better to have a big family. Everyone in the family can help each other when they have difficulties. What is more, the more children they have, the better life they will live when they grow old.
In my opinion, it's enough for a family to have one child. Nowadays population expansion is one of the most serious problems in the world. Population expansion contributes to a series of problems: shortage of natural resources and food supply,crowded cities and high rate of unemployment. Some day the earth will be too crowded for people to live in.
