I am a freshman majoring in water supply and drainage in Inner Mongolia University of Science and Technology, and I am very confused about the future of my major. Please help me analyze the advantages and disadvantages and future development of this major. I am a student of Inner Mongolia University of Science and Technology. You study water supply and drainage. I tell you, this major is still very good for employment in HKUST, but the employment environment is very difficult. You should be mentally prepared.
