Sudi

Produced in Suzhou, Jiangsu. Natural white bamboo is used, and Phyllostachys praecox (winter loggers) produced in Yuhang County, Zhejiang Province and growing for more than 3 years is the best. Only after natural drying and storage for more than one year can the pronunciation be crisp and not easy to crack. Select those whose fibers are firm, round and symmetrical, and the wall thickness is even, and cut them from the part above the bamboo root for 2-3 knots. After 25 processes, such as material selection, baking, peeling, reaming, flute plugging, tuning, winding and painting, the skill of tuning plays a decisive role in pitch accuracy.
