What is the distribution design, working prospect and treatment of communication room?

Not so good, I can only go to the design institute to learn this. Now that the high point of communication investment has passed, it is quite good to be a communication industry before 15. After 18, the scale of communication investment has shrunk, the division of labor has become more and more detailed, and the design fee has become lower and lower. However, there are more and more requirements and lower profits, that is, less money and more things. It is recommended to find a sunrise industry or a stable industry, and the communication infrastructure industry is basically saturated.
