Is geomantic omen one of the courses for civil engineering, architecture and other majors? What is the reason?

Yes, Feng Shui University offers courses. In coastal areas, especially in Fujian, Guangdong, Hong Kong and Macao, people believe in Feng Shui very much, especially businessmen. Comparatively speaking, the mainland is not so convinced.

In modern architecture, geomantic omen is sometimes used. Some of them are scientific and can be mutually verified with other courses in architecture. Our ancestors were still very capable. Don't underestimate Feng Shui.
