This is a mask emoji composed of two small masks. The upper left corner is the blue smiling face mask, and the lower right corner is the yellow face mask. Different platforms have different mask colors and different positions of sad and happy masks. This emoji comes from the ancient Greek drama-tragicomedy, also known as the drama. It usually has a happy ending. These two small masks represent the existence of two opposite and harmonious contradictions such as tragicomedy and the roles of good and evil in the play. It can also be used in general terms to mean drama, performance or masked ball
