Yunlong Village is located in the Liangzhu cultural zone. Humans have lived and multiplied in this area since the Neolithic Age, 6,000 to 7,000 years ago. According to the recollections of the elderly in the village, Yunlong Village has been a major silkworm production area in Haining since the late Qing Dynasty. From the late Qing Dynasty to the Republic of China, the silkworms raised by the villagers of Yunlong Village were local species, some of which could produce cocoons of various colors such as green and yellow. During the Anti-Japanese War, sericulture production was destroyed. Some families still raised silkworms and reeled silk by themselves, while some Yunlong people fled to Yunnan and brought Yunlong's more advanced silkworm breeding technology to Yunnan and improved the silkworm varieties. After the victory of the Anti-Japanese War, these improved varieties flowed back to Yunlong. The continuous improvement of silkworm varieties and the continuous improvement of silkworm breeding technology made Yunlong Village a well-known silkworm breeding village. After the founding of New China, the village became a silkworm production base for Zhejiang Agricultural University, Zhejiang Academy of Agricultural Sciences, and the Special Products Bureau. The basic content of Yunlong's silkworm production customs includes: (1) Breeding knowledge and skills. Knowledge and skills of silkworm rearing procedures such as collecting ants, first sleep, second sleep, third sleep (out of the fire), third sleep, and going up the mountain, knowledge of disinfecting silkworm rooms, knowledge of mulberry cultivation and mulberry picking, and traditional knowledge of preventing and controlling mulberry garden pests and diseases and silkworm diseases. (2) Belief in the silkworm god based on sericulture, including offering sacrifices to the silkworm god, using silkworm cats to ward off mice, inserting peach branches to ward off evil spirits, and making soup to treat silkworm diseases. (3) Various folk rituals of sericulture, such as the customs of performing silkworm dramas and fortune-telling, singing silkworm songs, and sweeping the silkworm fields. (4) Folk music and folk dances performed at relevant customary ceremonies, as well as folk literature and art related to sericulture, such as the silkworm lantern dance and the legend of the five silkworm saints. (5) The production techniques of various utensils related to sericulture, such as the production techniques of silkworm nets, silkworm plaques, and leaf cutting heads. (6) Various traditional silk reeling techniques. Yunlong sericulture production customs are an integral part of Wuyue culture. They cover all aspects of production labor and daily life, have penetrated into the daily life of local people, and are a vivid reflection of the real life in rural areas of Jiangnan. These customs, on the one hand, reflect the traditional sericulture knowledge spectrum in rural areas of Jiangnan, and also reflect the folk silkworm god belief with unique local characteristics, as well as various folk customs derived from the silkworm god belief, such as silkworm taboos and wedding and funeral customs. The various traditional manual skills reflected in the production of utensils required in the process of mulberry planting and silkworm breeding, the traditional silk reeling technology and various products closely related to silkworm breeding, reflect the unique regional cultural characteristics. The protection and inheritance of Yunlong sericulture production customs face certain difficulties. With the changes in the rural industrial structure and the increase in the proportion of industry and commerce in the entire production activities, sericulture production itself has a tendency to shrink, and the corresponding folk customs are gradually disappearing. Yunlong sericulture production customs have been included in the third batch of Zhejiang Province's intangible cultural heritage list.
