　　China has decided to end its decades-long one-child policy. All couples are allowed to have two children. This decision has aroused much chatter—whether it is high time that China should carry out the universal two-child policy or not. As far as I am concerned, this policy is in line with China's domestic situations.

　　Speaking from a macro perspective, this policy is a timely adjustment to China's changing situations. The aging population has been posing a threat to the sustainable and healthy development of China. This policy will optimize the demographic structure, increase the labor force, ease the pressure of aging population and ensure the sustainable and healthy development of the economy and society.

　　Speaking from a micro one, as the odds of having a weak elderly parent and all the attendant need for physical and financial assistance have jumped many times in just one generation, this policy will bring about many benefits to the family in the long run. In spite of the fact that child rearing is anything less than an easy task, the disadvantages, such as temporarily economic burden, seem to be pale compared with the benefits. The second child, at least, will accompany his or her sibling and in the future, they will share the responsibility to support and care for their old parents.
