Received a court summons from Didi loans overdue. What should I do?

I've been through this before, so forget it. In April this year, I borrowed 9000 yuan from Didi, and then I unloaded Didi, ready to change careers. I don't intend to pay back the money, and I won't reply to the reminder message of Didi Loan. As a result, I received a summons from the court in September, asking me to appear in court. At that time, the whole person was not very good, and finally I went to Didi Loan to pay back the money.
