Originally, I was traveling to Taiwan Province Province, but after the passports of the travel agency were issued, I found that several of us had lost them. How should I compensate the travel agency?

Have you seen your passport? It says: No individual or organization may detain a passport for any reason. Why did you hand it over? This is the only proof of your identity when you leave the country. Just like an ID card, you can only give them a copy if you want to use it.

The most important thing for you now is to get evidence to prove that your passport was lost by the travel agency.

Then apply for a civil lawsuit to the court where the travel agency handles the travel formalities. Or directly settle with the travel agency and lose money.
