Yangcheng is located in the southeast of Shanxi Province, at the intersection of Taihang, Taiyue and Zhongtiao Mountains. It has dense forests, abundant water resources, high terrain in the west and low terrain in the east, mild and cool climate, and superior natural environment is very suitable for the growth of mulberry trees. The sericulture custom in Yangcheng has a long history. It started in the Western Zhou Dynasty and flourished in the Tang and Song Dynasties. It has a history of more than 5,000 years. It is said that Huangdi's first wife Leizu taught people to raise silkworms in Yunmeng Mountain in Yangcheng, and King Mu of Zhou also visited Huoze (Yangcheng) to inspect local sericulture. In the thousands of years of history of mulberry planting, silkworm breeding and silk weaving, there has always been a continuous stream sericulture custom that has been infiltrated and passed down. It has developed in harmony with other cultures, forming a large number of poems, customs, etiquette, clothing and other text symbols related to mulberry, silkworm and silk, which constitute the rich connotation of sericulture customs. The traditional customs of silkworm songs, proverbs, affairs, taboos and operas, which originated from silkworms, celebrated because of silkworms and offered sacrifices to silkworms, have been deeply integrated into the daily life of the people, including clothing, food, housing, transportation, marriage and marriage of children. It not only enriches the spiritual and cultural life of the villagers, but also enables mulberry planting and silkworm breeding to be passed down in a wider space. This is also an important reason why Yangcheng sericulture can continue to this day with thousands of years of civilization history and stand out from the crowd. The sericulture custom is the crystallization of the long-term wisdom of the working people of Yangcheng, and cannot be replaced by modern technology. It is an extremely valuable historical and cultural heritage and must be vigorously inherited and developed. Sericulture culture is an important part of Han culture, which marks the maturity of agricultural civilization. In the long-term practice process, silkworm farmers pay attention to the observation of silkworms, continuously research and explore a complete set of sericulture custom processes, and summarize the selection and breeding of silkworms, seed production, mulberry feeding, disease prevention, taboos, etc. These customs have played an important guiding role in mulberry planting and silkworm breeding, silk reeling technology, mulberry silkworm culture and the promotion of sericulture in later generations.
