zhuó yīn
The heavy, turbid half of qi, the half that sinks. Suwen 5 uses it as the exact mirror of 清陽: as the clear makes heaven, the turbid makes earth; as the clear leaves by the upper orifices, the turbid leaves by the lower; as the clear opens the interstices and fills the four limbs, the turbid walks the viscera and goes home to the palaces. The word is not a synonym for evil here — in this chapter it is what remains after the clear part has been taken up, and its whole business is to descend. The chapter's pathology follows from the direction: 清氣在下，則生飱泄；濁氣在上，則生䐜脹 — the disorder is put as a reversal of the two directions.
