Lung Qi Deficiency
肺气虚 Fei Qi Xu Lung system
The Lung is too weak to breathe deeply or guard the surface. A quiet voice, shortness of breath on effort, a weak lingering cough, sweating in the daytime for no reason, and catching every cold that passes. Pale, tired, and easily winded.
The Lung is a bellows and a wall. When its qi is low the bellows is shallow and the wall has gaps, so you are both short of breath and open to every draft.
