What is the Taoist saying about primordial qi mixing?

Mixing elements is the achievement method of Buddhism, but Taoism doesn't say so. In fact, qi-mixing refers to imagining the whole body as a whole qi state in practice, no matter what the meridian and acupoints are, so as to simulate itself as an infinite state, that is, it is not divided into two devices and four images, but the most primitive and naive whole chaotic state.
