Who are the telephone and broadband installers recruited by China Tietong?

Telephone and broadband installation, the installation personnel of Tietong are basically contracted by other companies, not full-time employees of Tietong. What the installer has to do is to pull an external line (telephone line), break down, jump the wire in the computer room, and do the basic things well. When applying for a job, you should ask clearly about the salary and holiday time, and whether there is any holiday salary. Some contractors have no holiday pay. This practice makes perfect, and it takes a few months to get started. When you break down, you must pass your computer knowledge (otherwise, customers will not be able to communicate well). Requirements: first, not afraid of heights, and second, know something about computers (learn from the master)
