Single-parent families, especially single mothers, were under great pressure to survive in modern society.
China's situation was different from the United States in the United States, after a couple divorced, the man basically had an extra mother. The woman usually received a house and a child, and received monthly alimony, including double the alimony for the woman and the child. There might even be government subsidies and relief funds, so the situation was relatively better. In China, even if the property division was more fair, the woman could at most receive alimony for the child, and the amount might not be much. It was difficult to survive on this, so he had to go out and work.
