Most of the Chinese people think the family with one child is more better than the one with more than one child. For a thing, they want to build a successful career but have few time to bring up more than one child; for other thing, raise only one child they can afford better education for him. But others think this is better to have a big family. They think more children they raise, the better their life will be when they grow old. In my opinions, it's enough for a family to have one child, or population expansion will contribute to a series of problem.
