Lung and large intestine are the gold in life?

Lung and large intestine belong to gold in the five elements. "The lung is the lung, and it is the official." In other words, the lung is equivalent to a prime minister in the human body. The prime minister is responsible for governing the world and handling political affairs in the kingdom, just as the lungs specialize in breathing, proclaiming health, diverting water, taking pulse, participating in festivals, helping the heart and regulating the operation of qi and blood. Therefore, it is called "Fu Zhiguan". "The large intestine is the official of preaching", that is to say, the large intestine is the Ministry of Communications and plays the role of conducting dross.
