The excavation of Mawangdui's silk painting filled the blank of the silk painting in the early Han Dynasty, and also showed that it was the characteristic of this period to absorb the artistic connotation, style and image mode of Chu in the pre-Qin period. Many mythical images in T-shaped silk paintings are consistent with the description of Chu Ci, which is related to the modeling of Chu art.
