Interpretation: The word "Ba" follows the qi, and "Qi" refers to "chaotic qi". "Cause" refers to "inheritance and development", and the combination of "qi" and "cause" indicates the changing process of "chaotic qi drifting and gathering, frivolous people turning into heaven, and heavy turbidity turning into earth". The word "Ba" comes from Qi, which means "damp and hot water vapor", indicating that "chaotic Qi" has the characteristics of damp and hot. Because the creation theory of the ancient universe is the creation theory of the Guyue nationality, the Guyue nationality explains the formation process of heaven and earth with the formation process of typhoons in summer that they often see: on the sea surface, due to strong sunlight and rising water temperature, a large number of seawater transpiration, forming a loose hot and humid fog mass. Then, under the deflection force of the earth's rotation, countless hot and humid fog groups began to rotate in the same direction, forming a whole: typhoon. The longer and higher the typhoon, the faster it rotates. Finally, under the action of centrifugal force, its light components rise to form a "sky" and its heavy components fall to a "ground".
