It is difficult to raise a man and a woman, and there is not much flesh and blood support. What does that mean?

The benefits of fame turned out to be like this. It takes a period of hard work and running around. His son and daughter are doomed to be difficult to support. I don't have many relatives and friends. (surface)

It is said that a person (usually a man) has never done anything important in his life, and finally he gets nothing and is very tired. I haven't made any good friends, even a wife. (deep)
