The problem of strict array in synopsis of the golden chamber

The east corresponds to wood, so it is cyan and belongs to the liver. The south corresponds to fire, so it is red and belongs to the heart. The west corresponds to gold, so it is white and belongs to the lungs. North corresponds to water, so it is black and belongs to kidney. The middle corresponds to the soil, so it is yellow and belongs to the spleen. When the ancients applied the Five Elements Theory, it was basically not Jin Mu's fire, water and soil itself, but abstracted its characteristics and essence. The ancients could classify everything with five elements. Therefore, when understanding the ancient books of Chinese medicine, we must master some ancient philosophical knowledge in order to really learn Chinese medicine.
