Hu Bayi explains what the star feng shui art is.

Tianxing geomantic omen, also known as "Qingnang", is the most difficult branch of geomantic omen. Tian xing feng shui is the "heaven" referred to in the first wonderful book in the world-the incomplete volume of Feng Shui "Sixteen Characters of Yin and Yang Feng Shui", ranking first among the sixteen volumes. This is a knowledge of choosing a treasure trove of geomantic omen by observing the stars from above and examining the pulse from below.
