If you want to learn navigation-related subjects, such as maritime law, maritime management, shipping, electricity, port, electricity and marine engineering, I suggest you come to Dalian Maritime University for further study.
If you are a language major, I suggest going to Tianjin University. After all, it is a comprehensive university with strong strength in all aspects, and Tianjin is a municipality directly under the central government, with much more opportunities than Dalian. Tianjin University is better for study and future employment.
