In ancient China, the sequential symbol of a word was called "Tiangan", and there were ten symbols about Tiangan, namely: A, B, C, D, E, Ji, G, Xin, Ren and Gui. Ten symbols of heavenly stems are used in the cycle.

The Five Elements is China's ancient material view. The material concept of the five elements is mainly used in divination, philosophy and traditional Chinese medicine. Gold, wood, water, fire and earth constitute the five elements. Nature consists of five elements: gold, wood, water, fire and earth. The ups and downs of the five elements reflect the changes in nature and indirectly affect the fate of a person, a family, a society, a country and even the whole human race. The five elements affect the circular development of everything in the universe. The viewpoint of the unity of opposites of Yin and Yang in the Five Elements is the most primitive theory of the Five Elements.

And orientation is a kind of orientation about good or bad luck of houses in geomantic omen. A good house is mainly based on the orientation of the door, referred to as the Eight Houses Law, which points out the good and bad luck in all directions and is very particular. Geomantic omen emphasizes the law of eight houses' fate, which is also the main calculation method of eight houses' good or bad luck.

There are several aspects about the relationship between heavenly stems, five elements and orientation: in the east, A is a wooden pillar, and B is a wood flower and a wood fruit. In the south, C is the fire of the sun, and D is the fire of lamps and candles. On China side, E is the soil of the city wall and the soil of the countryside. In the west, Geng is axe gold and Xin is jewelry gold. In the north, benevolence is the water of rivers, while cinnamon is the water of rain and dew.

The same fire property, the same south, C is the fire of the sun, D is the fire of lamps and candles. The same soil, the same China surface, E is the soil of the city wall, and it is the soil of the countryside itself. The same metal, the same west, Geng is the gold of axes and cymbals, and Xin is the gold of jewelry. The same water, in the same north, is the water of rivers, and sunflower is the water of rain and dew.
