Nine tones and six tones: Yin Ping, Yin Shang, Yin Qu, Yang Ping, Yang Shang, Yang Qu, Yin Entering, Zhong Yin Entering and Yang Entering.
Nine tones and six tones are nine tones and six tones. Simple understanding: First, one tone corresponds to one tone, six tones correspond to six tones, and the other three tones are entering tones.
In fact, the pitch of the tones of Yin-in, Zhong-in and Yang-in is the same as that of Yin-in, Yin-out and Yang-out, and they are only distinguished by entering words ending in -p, -t and-K. Because of the definition of tone, it includes intonation (that is, actual pitch) and cadence.
