The Palace Museum. As early as the Tang and Song Dynasties, works with the theme of cats and butterflies appeared. The most famous is a picture of a cat and a butterfly drawn by Song Huizong himself. As of June 28th, 2022, this painting is now in the National Palace Museum in Taipei. This work establishes the mainstream cultural connotation and composition paradigm in the tradition of Cats and Butterflies. A cat looked up at the butterflies flying in the air, moved quietly and looked at Bi Xiao.
