I received a short message from the people's court today, saying that I was sued. The number is125200701889 8281421. He also said that I could contact officer Lin. ...

The news must be false. Don't trust him. Because, if you are really sued, the people's court will mail you the indictment of the other party, and you will sign it yourself without sending you a text message. The people's court liaises with judges and clerks in litigation matters. The police belong to the public security bureau, and the court is called bailiff, regardless of the prosecution.
