Is the tour group's ID card kept by itself?

Yes, during the tour, the identity or travel documents of the guests should be kept by the tourists themselves. When tour guides need to use tourist documents in their work, they should be taken back by the tour leader and returned immediately after use. When keeping the ID card of group tour, you should pay attention to putting the original in your underwear pocket. It is best not to lend it to others. If you let others do things for you, you should also entrust them to someone you trust.
