Friends say they are not at ease letting their children go abroad to play, so they let them join a tour group.

​I can only smile and remain silent: joining a tour group abroad is the most dangerous.

​There are all kinds of tricks, and there are special tour groups that are designed to increase the number of tourists in the group. If they can't empty your pockets, the rest will just be self-theft under surveillance. In any case, you won't escape; once you join a group, they will annihilate you.
