From "Reading the Medical Classics", a Chinese medical book written by Shen Youpeng in the Qing Dynasty.
Original text: The heart is the official of the monarch, where the spirit comes from; the lungs are the official of the life and pulse, where the management of joints is; the liver is the official of the general, where the planning comes from; the courage is the center of justice. When an official is appointed, the decision will come out; when the person is in trouble, the minister will make him an official, and the joy will come out.
Vernacular: The liver is an organ like a general, from which strategies come out; the liver is an organ like an envoy, from which joy comes.
