1. Negotiate with the other party: First, you can try to negotiate with the other party and explain your difficulties and pressures. I hope the other party can understand and pay the arrears as soon as possible.

2. Send a lawyer's letter or dunning letter: if negotiation fails, you can ask a lawyer to draft a lawyer's letter or dunning letter, clearly asking the other party to pay the arrears and emphasizing your rights and interests and legal status.

3. Sue the other party: If the above two methods are ineffective, you can consider suing the other party through legal channels. Relevant evidence and materials need to be prepared before prosecution, including contracts, receipts, invoices, bank transfer records, etc. In the process of prosecution, it is necessary to submit a complaint to the court and conduct litigation according to the requirements of the court.

4. Seek third-party mediation: In addition to the above three ways, you can also seek third-party mediation.
