The earliest turen was made by Jingpo children using two bamboo pipes, one thick and the other thin, of the same length. There is no sound hole on the tube. The production process is rough, the intonation is poor, and the sound range is less than one octave. Because the musical instrument originated from the memory of the dead in the wild, it was never played at home or in the village before.

Today's Turen is mostly made of a knotless thin bamboo tube. The length of the tube varies from 38 cm to 55 cm, and the diameter of the tube is 1.1 cm to 1.4 cm. An oval blowing hole is opened in the middle of the bamboo tube slightly to the left. , the aperture is 1 cm at the longest point and 0.7 cm at the widest point, the hole wall is trimmed sharply, thinly and symmetrically, and there is no sound hole on the tube body. The Chinese Musical Instrument Museum of the Institute of Music of the China Academy of Arts in Beijing has a spit of the Jingpo people. This Tu Ren was donated by the Yunnan Mass Art Museum in 1958. In recent years, the musicians of the Yunnan Song and Dance Troupe have reformed the Tu Ren. The tube body is formed by socketing two diabolo tubes. The interface is connected with a copper socket, and the pitch can be adjusted at any time. This reformed spit, the tube body is 65 cm, the inner diameter of the right end is 1.6 cm, and the inner diameter of the left end is 1.2 cm, and there are two small sound holes above the left end near the mouth of the tube, which are used when playing bb2 and c3 vibrato, improving the treble 's performance.
