Yesterday evening, 3 friendly concerts were held in Shaoxing at the same time. At the City Square Concert, the large square became a classroom and the local people were given a vivid music lesson. Seoul Choir from South Korea brought their national musical instruments; Voice Print Choir from Sri Lanka played the drum, guitar and electronic organ, etc., which made the local people experience modern music at a short distance. Some performers even played B-Box , imitating various sounds with their mouths. The locals enjoyed it so much.
