According to www.cultureofchina.com , there is no standard notation for Chinese music. The various methods may be grouped under: pitch system, descriptive system, hand-and-finger system, Kung Ch'e
system, rhythmic recitation and numerical system.
Chinese music is written according to a number system, known as jianpu, which means "simplified notation" in Chinese. The system's invention is attributed to Jean-Jacques Rousseau (1742) but its development continued in the hands of Pierre Galin (1786-1821), Aimé Paris (1798-1866), and Émile Chevé (1804-1864). In some circles Chinese number notation is simply referred to as the French Chevé system. Variants of the number system are utilized all over Asia.
Nowadays, Chinese musicians can read western notation as well as Chinese. Many of them, when working from a Western staff notated part, will annotate it with the number system, since this is more native to their training.
The number system is similar in many respects with Indian notation, the main difference is that in Indian notation letters, representing the notes of the gamut, are utilized, whereas in Chinese notation numbers are employed. Like Indian notation, Chinese notation can be very useful as a musical shorthand.
