I am a student majoring in highway engineering in Chang 'an University. The three ace majors of Highway College are Highway, Bridge, Tunnel and Tongji Bridge, and the best is it. Undoubtedly, the long bridge is also good, and the employment is good, but the treatment is hard to say. Depending on the specific unit, the conditions may be difficult. At present, the employment in tunnels is the most optimistic, with 100% employment, but the working conditions are still relatively difficult. There are also roads and bridges dominated by boys, and the employment of girls is similar.
