Vertical style architecture —The vertical pillar in Chinese traditional wood structure building is a sky-reaching symbol that connects heaven and earth. Its base is earth, in the form of a stone drum or a golden melon symbolizing mother's body - the origin of life, and the top crossbeam is the sky.
The yin-yang view in house building is shown in two yin-yang pillars heading down towards earth and crossing tails at the "sky beam." It is the same concept as the view on dragon totem that yin-yang dragons having their heads on earth and mating in heaven. The closure of the building is the connecting point of two dragons. A rite of worship is held on the closing day and an eight diagram graphic is pasted over the closing point. A pair of crossing chopsticks is placed on top, forming a symbol of perpetual life, with a black cloth rooster in the center as the symbol of the sun.
