According to Baidu Encyclopedia, Ude Qin is a short-necked pipa, which usually has six strings 1 1, five strings 10 and seven strings 13. Udine is different from western pipa in musical instrument structure and playing techniques. The most obvious difference is that Udinese has no personality and a smaller neck. Udine's variant musical instruments are Nadi, Middle East tambourine and Arabic drum set. These instruments are different from Ude Qin in playing style, musical characteristics and uses, but they all originate from Ude Qin, a prototype instrument.
