Jiangnan is good, looms are outstanding, peacocks make up flowers in the clouds, and ice silkworm spits chicken and fog. What does it mean to be a new little dragon?

"Jiangnan is good, the loom is better than nature, the peacock's makeup is rotten, and ice silkworm spits chicken and fog, which is a new kind of little dragon." This is a poem by Wu Meicun, a poet in the late Ming Dynasty, praising Yun Jin (but the "Yun Jin" in the poem does not refer to a piece of cloth or a noun). In fact, there was no such word as brocade in the Ming Dynasty. At that time, the satin that entered the royal family was called Kujin, Ku Sa Ding and Zhuang.
