What is China's pentatonic notation?

The ancients matched the five tones with the five internal organs: the spleen should be in the palace, and its sound should be slow; The lung should be business, and its sound should be clear; The liver should respond to the angle and have a long voice; The heart is giving, and the voice is bright; Kidney should be feathered, and its sound is heavy and thin, which is the correct pronunciation of the five internal organs.

Equivalent to the current 12356, that is, do, re, mi, sol, la.

"Gong, Shang, Jiao, Zheng and Yu" are the names of five different sounds in China's pentatonic scale, which are similar to 1, 2, 3, 5 and 6 in the current notation. That is, the house is equal to 1(Do), the quotient is equal to 2(Re), the angle is equal to 3(Mi), the number is equal to 5(Sol), and the feather is equal to 6(La).
