The background of the movie was the love story between a white snake and a green snake in ancient Chinese mythology. The name "green snake" came from the color of the snake body that the white snake transformed into. In traditional Chinese culture, cyan was considered a mysterious, elegant and rich color. Therefore, turning a white snake into a cyan snake was also a description of its personality. At the same time, the name " Green Snake " also hinted at the love story between the white snake and the green snake, which made people think of the emotional entanglement and mutual dependence between the two.
