What are the main organizational forms of silk patterns in Song Dynasty?

The main organizational forms of silk patterns in Song Dynasty are bi-directional linking pattern, group pattern, branch-breaking pattern and branch-piercing pattern. Double-sided continuous form is mainly used for edge decoration of sleeves, lapels and collars. Judging from the unearthed objects, there are many production methods such as gold seal, embroidery and painting, which are continuous, scattered and antagonistic. Themes include camellia, chrysanthemum, plum blossom, peony and birds and butterflies. Pattern assembly is to make the material into a circular unit pattern, and then make a regular scattered arrangement on the plane fabric according to the word rice. For example, the carved ball patterns unearthed in Alar, Xinjiang, and the tapestry of heavy lotus flowers all belong to this form, and the group flowers also have the significance of celebration and reunion. Broken branch fancy is a single flower with flower head, branches and leaves as the unit pattern, and then dispersed, which has the characteristics of realism, vividness and nature. The characteristic of the branch-piercing fancy is that the four seasons and flowers are connected by branches, and all kinds of animals fly in it, which appears in the form of dynamic and static combination, and the pattern is very complicated.
