Su Di

Su Di

　　Produced in Suzhou, Jiangsu Province. It is made from natural white bamboo, with the best quality coming from “Lajiao” bamboo (harvested in winter), which is grown for over three years in Yuhang County, Zhejiang Province. It must be naturally air-dried and stored for more than a year to produce a clear tone and resist cracking. Only pieces with firm fibers, uniform roundness, and consistent wall thickness are selected, cut from the 2nd–3rd nodes above the bamboo root. The production involves 25 processes, including material selection, baking, peeling, hole drilling, corking, tuning, wire wrapping, and varnishing. Among these, the tuning technique plays a decisive role in the accuracy of the sound.
