It is feasible to change from civil engineering to teaching. It is best to transfer to a department related to this major, such as Civil Engineering College.

Civil engineering not only refers to the application of materials, equipment and technical activities such as survey, design, construction, maintenance and repair, but also refers to the object of engineering construction. That is, all kinds of engineering facilities, such as houses, roads, railways, pipelines, tunnels, bridges, canals, dams, ports, power stations, airports, offshore platforms, water supply and drainage, protection works, etc., which directly or indirectly serve human life, production, military affairs and scientific research.

Civil engineering majors learn the basic theories and knowledge of engineering mechanics, fluid mechanics, geotechnical mechanics and municipal engineering. It mainly trains high-level engineering talents who are engaged in technical work and research work such as planning, survey, design, construction and maintenance of railways, highways, airports and houses, bridges, tunnels and underground projects. Graduates can engage in teaching, design and scientific research in universities, design departments and scientific research units, and also engage in technical work in management, operation, construction and real estate development departments.

If you want to change careers as a teacher, you must teach something related to these courses.
