Street scams.

There are a lot of them, look at those pirate magazines, the advertisements in them, they are all about ecstasy, tasers, etc. These drugs can put a person in a semi-comatose state for an hour or so. These drugs can make the person who takes them in a semi-comatose state for 3-5 hours, and they will not wake up if they are beaten or shouted at, or if you ask them what they are, they will answer. Others can make your favorite boys and girls obey you for 6 months, only like you and ignore others. The same thing happened to us. So walk around and don't talk to strangers. They often just let you sniff a little and you're at his mercy. A woman worker in our factory came back to the workshop at night not long after work and went around borrowing money. When my good friend asked him why he borrowed money, he couldn't tell me why, so he dragged him to the bathroom (a lot of things like this happened during that time, so I was very suspicious) and washed his face. He didn't know what was going on.
