The immigration receipt is missing. Can I pass through Dongning Port?

I can't. According to the query, the World Wide Web shows that. If it is damaged or lost carelessly, you should immediately verify the passport information with the entry-exit administration department and reissue a copy of the entry-exit card, and make a registration record on the copy and mark it in the "Remarks" column accordingly. If the party concerned is too late to go to the entry-exit administration office because he is about to leave the country, he can send a registered letter to the entry-exit administration office explaining the reason for losing his entry card or explain the situation to the airport border inspectors. Specific measures should be confirmed by contacting relevant personnel in advance. So you can't pass through Dongning Port.
