What does "pentatonic scale" mean? Where did it come from?

The pentatonic scale refers to the horn, sign, palace, business and feather in China's pentatonic scale, which has five tones and five elements: horn (wood), sign (fire), palace (earth), business (gold) and feather (water).

The interval between two adjacent sounds in pentatonic scale is two degrees, except for the third degree between the horn and the sign, the feather and the palace (the house with an octave higher), which is different from pentatonic scale: shouting, laughing, singing, crying and groaning belong to one of the five elements.
