There are many people who choose Dink in contemporary society. I think there are several main reasons. The first is that raising children is too stressful. In contemporary society, the economy is developing rapidly, but the work pressure is also great.
Many people earn only enough to support themselves and barely support two people. And many people are burdened with house debts and have no extra money to spend on their children. So I simply choose not to have children, which will neither make children suffer nor increase their financial burden. But there should be no such reason in Li Jian. Because as a singer, he should not have any financial pressure.
The second is life. If you have children, you will definitely break the world between yourself and your wife. Although not having children may have a certain impact on your later life. But as a person, you should learn to enjoy it, so it may not be so important to have children. Because a person living in society should be happy. So personally, I think this is the most important reason why Li Jian doesn't want children.
