Guzheng was originally a rather simple instrument with only five strings. After all the years of evolution, today's Guzheng has twenty-one strings and is still widely used in all kinds of Chinese music. Guzheng has a unique, rippling sound character. The playing techniques developed for Guzheng are also unique and distinct, therefore set it apart from any other members in the world's zither family.";
