I once worked as a part-time network administrator in an internet cafe during the summer vacation. At the beginning, when I didn't contact Internet cafes, I always felt that network management was a very serious person in society. Later, I learned that network management is actually a very simple job. The work of network management is very boring. The job of network management is to help people open the time on their ID cards. If there are people, they will be a little busy. If there is no one, most of them are playing with their mobile phones and can't do anything else. The job of network management is easy, but the salary is also very small. However, the advantage of being a webmaster is that you can know many friends who like surfing the Internet, and you can also know more good friends who play games. This is also a very good experience.
