Extended data:

According to China's Loan Contract Law, the borrower should repay the loan at the agreed time and amount, otherwise it should bear the liability for breach of contract. There is no legal provision that clearly stipulates how a loan default will affect a child's college education, but in fact, a loan will not only have a negative impact on the family's economic situation, but also affect a child's chances of receiving higher education. Therefore, timely repayment of loans is the best choice to protect families and children.
