How many young people live in bridge opening?

A dozen. There are more than a dozen young people living in bridge opening. Many young people prefer to wander outside and sleep on benches in bridge opening and parks rather than work in factories. Because many people have been to the factory, they feel that working in the factory has almost no future. This group of young people live collectively under the bridge, sleep on simple plastic mats every day, and keep their hands on their mobile phones every day. The only thing they are interested in doing is playing games, taking out lunch boxes and plastic bags and walking around the young people.
