Gilt Grottoes Swallowtail Butterfly

Archaeologists discovered an unfinished Tang Dynasty flying apsara mural in the Dunhuang Grottoes. In the painting, a flapping swallowtail butterfly rests on the eyebrows of a goddess. In the middle of the night, when the mural was lighted, the butterfly flew out and led him through a sandstorm night thousands of years ago. In order to save his beloved mural, the painter painted the last stroke of blood with blood. The soul turned into a butterfly and stayed in the eyes of the goddess forever, guarding the unspoken love and civilization.
