Lerong, also known as Songkanlerong, is a unique musical instrument of Jingpo people. In Jingpo language, "le" means straight, and "velvet" means beautiful. Songkan is a place name. It is a village inhabited by Jingpo people in Myanmar, which is adjacent to Yunnan Province, my country. It is also the origin of musical instruments. Jingpo language is also called velvet or brushed velvet.

The velvet tube, made of bamboo, is developed on the basis of bamboo shoots. It consists of a ventilation tube and a sound tube.

There are bamboo joints at both ends of the air supply tube, the length of the tube is 40 cm to 50 cm, and a small hole is opened at the upper end of the tube near the bamboo joint, and a thin gold bamboo tube with a length of 3 cm to 6 cm is inserted as a mouthpiece. Both ends of the air delivery tube are tied to the sound tube with ropes, and the two tubes are juxtaposed. At the upper ends of the air supply pipe and the sounding pipe near the bamboo joint, there is a ventilation bamboo pipe connecting the two pipes. The sound tube, also known as the supervisor, is made up of two bamboo tubes that are spliced together. The length of the tube is 100 cm to 115 cm, and the diameter of the lower end is 1.4 cm. The four sound holes are opened on the body of the lower cut pipe, the hole spacing is different, and the back holes are opened on the body of the upper cut pipe. All the connecting parts of the bamboo pipes should be sealed with beeswax to avoid air leakage when playing.
