Is there a university in China that specializes in Feng Shui and Yin and Yang?

Don't! In the past, there were Feng Shui classes for architecture majors, but only some skins were involved. I don't know now. It is impossible for a regular university to learn Feng Shui. Our country does not advocate or oppose Feng Shui. There are private schools to study. There is a Sinology University in Wuhan run by the people. An old gentleman I know teaches there. You can check the situation online. What I can tell you is that Feng Shui is a highly applied subject, and light theory is far from enough, and it must be mastered through a lot of practice.
