The mechanical specialty of Dalian University of Technology is first-class in China, and descriptive geometry and mechanical drawing compiled by the Engineering Painting Department of Dalian University of Technology are the basic courses of mechanical departments in domestic universities.

In addition, the mechanical departments of Northeastern University, Dalian Maritime University and Liaoning University of Engineering Technology are also very good choices. Each has its own teaching characteristics and emphasis.

Official website in these schools has a description of special subjects. Might as well go and have a look. The introductions there are all more authoritative.
