Nantong Banyao Kite Making Skills Extension (Whistle Making Skills), a traditional skill project in the fourth batch of representative projects of Nantong Municipal Intangible Cultural Heritage. The whistle making skills can be traced back to the Song Dynasty, because kites with whistles have become popular in the Song Dynasty. Later, they were lost everywhere, and only Nantong and some nearby areas still retain this feature. There are three main raw materials for whistle making: bamboo tube whistle, gourd whistle, and ginkgo whistle. Whistles can be divided into high, medium and low parts due to different textures. Whistles of the same texture can be divided into several pitch levels due to size. Hundreds of whistles are installed on a kite in sequence, facing the wind, and the wind blows the whistle, forming a beautiful melody with the wind force. The bamboo tube whistle is divided into three sections, arranged vertically according to the thickness of the bamboo tube. The larger one is as thick as a teacup, and the smaller one is only the size of a pen. The gourd whistle, the larger one is like a basketball, and the smaller one is like a ping-pong ball, and its sound is "buzzing". The ginkgo whistle is carved from the shell of the ginkgo tree. It has a thin and sharp sound and is suitable for small kites. Both the mother-and-child whistle are mainly made of bamboo. The difference from the ordinary whistle is that the large mouth has a small mouth and has multiple sounds. The production of ordinary whistles requires more than a dozen sets of processes, while the mother-and-child whistle takes three times as much time as the ordinary whistle.
