Dragon Boat Singer

This painting is believed to be done in late 1920s to early 1930s, it is a 136 x 112.3 cm four scrolls painting, the person in the painting is a dragon boat singer that used to go door to door to sing or chant verses of luck and fortune in order to get some money in return, the bamboo dragon boat had some mechanism covered by the cloth, when the person sang, he would trigger the mechanism to move the paddles and human figures, he also carried a small gong and hand drum on his body so he could beat out some rhythm when he sang, I think there is no body doing this anymore since the early 1960s.
