Really? I want to learn to operate a tower crane.

Don't believe everything on the website. Generally, Baidu Post Bar can still be trusted. I shouldn't be fooled by teaching you this method. Search on QQ, no matter where you are in the city, you can search for groups. For example, if you are in Wuhan, search Wuhan Tower Crane Group. Qingdao tower crane group Qingdao search. There are many such groups and many people to find. The group here is not deceptive. Members should be familiar with it and have been kicked out long ago. I hope it helps you. I suggest you change careers. The tower crane industry is not easy to mix, and it is useless to suffer. Bullies are hardworking people.
