Hey, play the instrument. Primitive society has emerged. The origin of forest is related to the labor and production activities of ancestors. It turns out that ancestors may have imitated the sounds of birds and animals to trap prey. With the progress of society, it is regarded as a simple musical instrument, and gradually increases the sound hole (referred to as sound hole), and develops into a melodic instrument that can play tunes.

In primitive society, there were many kinds of utensils. The pottery pier of Hemudu site in Yuyao County, Zhejiang Province is oval, with only air holes and no sound holes, about 7000 years ago. Tao Di in Yangshao Cultural Site, banpo village, Xi, Shaanxi, looks like an olive with only one air hole. It is made of fine mud, which is one of the original forms of graves about 6000 years ago. Three pottery pots were unearthed from Jingcun Site in Wanrong County, Shanxi Province. One pottery pot has two sound holes (illustrations of China Music History Ⅰ-22 to Ⅰ-26). Neolithic pottery was found in Yaoguanzhuang in Weifang, Guandong in Yuanqu, fengcun in Yuanqu, Yijing Village in Taiyuan, Dahe Village in Zhengzhou, Henan, Wang Yang Temple Site in Anhui and Dadunzi Site in Pixian, Jiangsu, belonging to different primitive cultural regions.

Clay with pure soil and no sand and gravel impurities should be used to make pottery pots, and the color is not limited, and it can be red, yellow or black soil. Add clear water into clay, stir and knead repeatedly to make a mud block with moderate hardness, and then knead, shape, slice, polish and calcine it. Professor Cao Zheng of China Conservatory of Music has accumulated rich experience in making antique pottery urns since 1930s. From 1979, Professor Chen Zhong of Tianjin Conservatory of Music developed a nine-hole pottery urn.
