Reading WATER PUPPETRY Have you ever seen a water puppet show? It is so special and fantastic. It’s a unique Vietnamese tradition. Children love the performance, and tourists who come to Viet Nam greatly enjoy this kind of art. Water puppetry ( Múa rối nước) is a traditional art form. It began in the 11th century. It originated in the villages of the Red River Delta of North Viet Nam. The show is performed in a pool. The puppets are supported by strings under the water and controlled by the puppeteers behind a screen, so they appear to be moving on the water. The puppets are made of wood and then painted. The themes of the puppet show are rural: the performances show everyday life in the countryside and folk tales. There are stories about rice farming, fishing, and Vietnamese village festivals. 1.
