Chuzhuang, a village in Linyi city's Hedong district, has made them for more than 340 years. They were sold in the provinces of Jiangsu and Hebei, providing one of the main sources of income for the locals.
Some of the fine Chuzhuang clay whistles have been kept by State-level museums and have won national awards. They've also become part of cultural exchanges between China and other countries.
Nowadays, however, there are few craftsmen in the village, so the skill is in urgent need of inheritance and protection. (Edited by Xue Xinyi)
