What should I do if others don't pay me back? How can I get it back?

The solutions for others to borrow money and not pay it back are: 1. If they are temporarily unable to repay, they can communicate with the debtor and negotiate to reach an installment repayment agreement; 2. If the debtor refuses to repay, he may bring a lawsuit to the people's court to demand repayment of the debt; 3. Those who meet the requirements can apply to the court for a payment order. According to the relevant laws and regulations, if the creditor requests the debtor to pay money or securities, it may apply to the grassroots people's court with jurisdiction for a payment order if the following conditions are met: (1) There is no other debt dispute between the creditor and the debtor; (2) Payment orders can be served on the debtor. The application shall specify the amount of money or securities required and the facts and evidence on which it is based.
