Is it good to pull the cable in the corridor of the community?

Generally speaking, cable drawing does not have much technical content. Ordinary people can learn it in a few weeks, and if they maintain it, they can learn it in a month or so. A little tired. To go to different customers' homes, a bad review will deduct money, and often take advantage of the platform. They only recruit young people, and they are usually fired after middle age, which is inhuman. Keep recruiting young people and keep firing people.
