Let's just say that anything related to network and communication will do. The key is whether you have that ability.
Construction units: such as China Communications Service Co., Ltd., China Communications Construction Group Co., Ltd., which are engaged in technology and project management, and the provincial telecommunications engineering bureaus, or you can go to major telecommunications research institutes, such as the former Telecommunications Research Institute of the Ministry of Information Industry.
Communication consulting design units: such as Zhongxun Design Institute (Zhengzhou ministerial level), Beijing Mobile Design Institute (Beijing ministerial level), Guangdong Telecom Design Institute and Zhejiang Huaxin Institute (these two institutes are the best at the provincial level).
Major operators (China Mobile, China Telecom and China Unicom) can do everything, including project management, equipment and line maintenance, finance, marketing and technical support. Communication equipment manufacturers (Huawei, ZTE, Fiberhome, Datang, Ericsson, Motorcycle, Alang, Nokia Siemens) and communication test instrument manufacturers such as project management, project supervision, equipment sales, training department and contract management sales. For example, Guangdong Engineering, Beijing Yujinqiao Supervision Company and Zhengzhou Huaxia Supervision Company are responsible for auditing communication projects and engaging in the construction, operation and maintenance of private networks in various party and government organs, enterprises and institutions, such as public security, taxation, highways, traffic police and traffic monitoring.
Then study PhD, stay in school to teach, be your own boss, engage in communication engineering construction, design, supervision, equipment debugging or instrument sales agent, and so on.
By the way, you can also be a signalman!
Work hard, although communication is hard, but the prospects are not bad.
