I got the message and went to the justice bureau to get the express. What happened?

Legal analysis: That depends on what kind of document it is. See if it's a prosecution document or something, but if there is contact information on it, it's best not to reply in the past for fear of fraud. If it's not too much trouble, then take the document to the court or the judicial bureau to ask clearly.

Legal basis: Article 4 of the Provisional Regulations on Express Delivery. No unit or individual may use letters, parcels, printed matter and other delivered articles (hereinafter referred to as express delivery) to engage in activities that endanger national security, social public interests or the legitimate rights and interests of others. No unit or individual may illegally inspect other people's express mail except for the inspection by relevant departments according to law. No unit or individual may open, conceal, destroy or resell other people's express mail without permission.
