Parents are not obliged to give adult children living expenses, but they must. Therefore, even if parents don't have to pay any fees for their children in law, in fact, the main source of income for most college students is their parents.
? First of all, students really don't have enough time to do part-time jobs. Some specialized courses can rest from morning till night, so they can also rest on weekends. Usually, there is no full-time part-time job. Therefore, many students who want to be financially independent may not rely entirely on their parents for food and clothing, but their parents' help is indispensable for large expenses such as tuition fees. After all, there are very few students who can take care of themselves completely, and learning is the main thing, so give children some financial assistance so that they will not delay their studies for money.
In short, obligations belong to obligations, and feelings belong to feelings. The most direct material expression of parents' love for their children is to give money, because it is difficult for parents to provide direct help to their children in their studies, so taking care of their children becomes financial support. Even if they don't have this obligation, they will still give financial support out of love for their children.
