Volume 1 (the weaving or silk section) of the Qianlong-era illustrated Yuzhi Gengzhi tu, in Chinese. It has 23 woodblock-style plates showing silk production from bathing silkworm eggs, the molts, mulberry gathering, cocoon selection, reeling, and warping to weaving on a loom, dyeing, and making garments. Each plate has a title, imperial poems and a caption. The images show household scenes with women, looms, reeling frames, and dyeing racks. There are no weaving drafts.
