"The mask itself has a double meaning ... In the extroverted" image dance ",it depicts the shape of the imitated animal or other creature ... In the introverted" dance without images ",the mask does not have the form of expressing reality, but is copied by the wizard or the wizard who saw it in his dream." Moreover, "(mask) serves two basic forces that we are familiar with, and its purpose is to strengthen the power of moving through color, style and texture. On the one hand, it helps dancers to rise from the self-feeling of daily life, free themselves from themselves and enter the realm of bliss; On the other hand, it strengthens the simulation characteristics of' image dance'. Therefore, Sachs believes that "masked dancing has an obvious contradiction, that is, performers should try their best to deny themselves and succumb to the morality of the role while highlighting their own personality."
