Passports are detained by immigration authorities in foreign countries. Can I ask the consulate for help?

No, the consulate is a place to stamp and sign. If you lose your passport, you can reissue it at the consulate.

If your passport is detained, you should wait for repatriation or apply for a China travel permit at the embassy or consulate.

Passport is a legal document issued by a country to prove the nationality and identity of its citizens when they enter and leave the country and travel or stay abroad. The word Passport means port pass in English. In other words, a passport is a passport for citizens to pass through international ports in various countries. Therefore, some countries in the world usually issue passes instead of passports.
