雰霧（又作氛同敷雲反釋名云氛粉也潤氣著草木因冷則色疑白若粉也尒疋云地氣發天不應曰霧霧陰氣溼也）。

雰霧 (also written as 氛, the same, with the fanqie 敷雲反 [*pʰjun*]; the Shiming says: '雰 means powder. Moist vapour clinging to grass and trees congeals white like powder when cold.' The Erya says: 'When earthly vapour rises and heaven does not respond, it is called 霧 [fog]; fog is yin vapour and damp').
