What does it mean that the middle limit gradually makes money and rushes back to China, and the husband and wife are less punished, and the ultimate limit is wealth?

This is a proverb of China, which means that after middle age, they gradually get rich and go to the country again, with few couples and rich life in their later years. It means that with the growth of age, people will gradually become rich and succeed again, and in marriage, there will be fewer contradictions between husband and wife, and they will enjoy honor and wealth in their later years.
