Detailed explanation of ternary triad compass on 25th floor of Taiwan Province Feng Shui Museum.

If you really want to learn the compass, there is a book in each circle, and each book is equivalent to 6-8 credits in the university. After studying on the 25th floor, I graduated in four years. Generally speaking, Wu's Compass, Qin's Compass, Wang Tingzhi's Compass for Running a Class, Wu Jinguohe's Divination, Zhang's Divination and Twenty-eight Nights Back to the Mountain and Tibet can all be used as blue books for entry and further study.
