Parents of minors suspected of selling K fans should:

Parents of minors who have been arrested can go to the case-handling unit and ask for an arrest notice to know what the minor has committed. For crimes involving minors, send them living expenses or warm clothes by going to the detention center or by mail. If necessary, you can communicate with the minor by writing letters and ask him to cooperate with the investigation of the investigative agency. At the same time, you can also go to a legal aid agency to apply for legal aid and consult a lawyer about the protection mechanism for minors.
