Nuo sacrifice is one of the customs of the ancient Chinese New Year. It is composed of Nuo song, Nuo dance and Nuo opera. It is a local religious sacrifice activity to exorcise ghosts and evil spirits. At the ceremony, the masked man acted as the God who drove away the plague, called Nuo God, and performed some dance movements. The dancers and masks in the picture, with a red background, look lively and mysterious.
