A popular saying in China has it that “There are three forms of unfilial conduct, of which the worst is to have no descendants.” But now, it is quite fashionable for many young couples to choose a lifestyle without kids and organize the DINK family. Some couples who have chosen to be DINK are obliged to do so. Some couples are fearful that they cannot provide favorable living conditions for children. Nowadays, the cost of educating a child is much higher than before. In big cities, to send a child to a better kindergarten takes a large amount of money and the key primary or secondary schools are even more expensive. But when they make preparations for having a baby, it is a pity that they have missed the most fertile years.
