my country is the first country in the world to engage in sericulture. In the middle of the Neolithic Age, five or six thousand years ago, our ancestors began to collect mulberry leaves, raise silkworms, and weave silk. Sericulture is an important part of China's traditional agricultural culture. The "Yu Gong" chapter of the "Book of Documents", the earliest Chinese classic, records that "mulberry soil is already silkworms". The "Shan Quanshu" of the "Guan Zi" in the Spring and Autumn Period also says that "the people are familiar with sericulture". The poem "Luo Fu is good at sericulture and mulberry, picking mulberry leaves in the south corner of the city" in the Han Dynasty Yuefu "Moshang Sang" describes the folk sericulture customs, which is even more popular. Sericulture is the crystallization of the wisdom of the Chinese nation and the source of the "Silk Road", a channel for cultural exchanges between China and foreign countries. In the process of the emergence and development of the sericulture industry, many beautiful customs of respecting silkworms, cherishing mulberry leaves, loving silkworms and protecting mulberry leaves have been formed all over the country, and have been passed down from generation to generation among the people. Activities such as offering sacrifices to the silkworm god and rolling silkworm flowers are the more prominent parts of them. Together with other sericulture customs, they constitute the historical witness of the development and prosperity of the ancient Chinese sericulture culture. Sweeping the Silkworm Field is a silkworm custom widely spread in the Hujia area from the late Qing Dynasty to the Republic of China. It originated in Deqing County, Zhejiang Province, and the main performers of the ceremony were concentrated in Deqing. From the late Qing Dynasty to the Republic of China, in order to pray for a good harvest of silkworms and mulberry trees, Deqing silkworm farmers invited professional or semi-professional artists to their homes during the Spring Festival, Lantern Festival, and Qingming Festival to hold a ceremony of sweeping the silkworm field. Later, it gradually evolved into a song and dance performance. During the ceremony of sweeping the silkworm field, a woman in makeup usually sings and dances, accompanied by a small gong. The lyrics are mostly wishes for a good harvest of silkworms and a description of the whole process of silkworm production. In conjunction with this, the performers often perform a series of actions related to silkworm production, such as sweeping the floor, pasting windows, dusting silkworms, picking mulberry leaves, feeding silkworms, catching silkworms for plaques, going up the mountain, and picking cocoons. "Silkworm flowers" are the most auspicious things in the minds of the people of Deqing, and the performance of sweeping the silkworm field is therefore very popular among local silkworm farmers. Sweeping the silkworm field is an important part of the silkworm production custom. Every year during the Cold Food Festival and Qingming Festival, before "closing the silkworm room door" for production, silkworm farmers invite artists to perform at home in order to eliminate all disasters and bad luck and pray for a good harvest of silkworms. The performance of sweeping the silkworm field has thus taken on a certain ritual nature and has become a symbolic reflection of Zhejiang's sericulture production, with high value for folklore research.
