What are the primordial qi, middle qi and residual qi in the eight characters?

First, the original gas, middle gas and residual gas are in twelve branches, and each branch has one, two or three heavenly stems circulating in it. The heavenly stems circulating in Tibet are divided into original gas, middle gas and residual gas according to their strength. This kind of qi with the same attributes as the five elements of the soil branch is the most powerful; Neutral gas, where the local gas loss is the smallest, the intensity is in the middle; Residual gas and ground support have the greatest loss to local gas, and its strength is the weakest.
