"Clay whistle", commonly known as "baby whistle", also known as "clay whistle", is a folk toy in Guanzhong, Shaanxi. It is said to have originated from Yuhuazhai in Xi'an in the late Qing Dynasty and early Republic of China. It is a colorful low-temperature pottery toy whistle with a plump and concise shape. It is mainly based on drama characters, but there are also small fat babies and small animals, the smallest of which is only an inch. In the early 1950s, Xu Wenyue, who was in his 20s, began to learn to make clay whistles, and it has been more than 50 years since then. A "baby whistle" has to go through more than ten processes from taking soil, mixing mud to making blanks, molding, whistle penetration, drying, baking, painting, and covering with oil, etc., and it takes three or four days to complete. The selected clay must not only be sticky, but also must be uncontaminated. After a few days of drying and baking, these clay figurines made with molds are painted with eyebrows, beards and colorful clothes. These clay figurines become "Zhao Zilong", "Jiang Ziya" or "Erlang Shen". Clay figurines with holes on their heads can make sounds when blown, and are called "baby whistles". Clay figurines with holes on their feet cannot make sounds when blown, and can only be inserted into sacrificial boxes, called "sacrificial clay figurines", and used as gifts at funerals. In May 2007, Xu Wenyue's handmade clay whistle-making skills in Dizhai were included in the first batch of intangible cultural heritage lists in Shaanxi Province; in June 2008, it was identified as the first batch of intangible cultural heritage in Xi'an.
