The tihu is a two-stringed bowed vertical fiddle in the huqin family, used in Chaozhou xianshi music of the Chaozhou people. It is an adaptation of the gaohu used in Cantonese music. It has a tubular hardwood body that is covered on the playing end with python skin. It is used in the Chaozhou people's original homeland of Chaozhou and Shantou, in eastern Guangdong, as well as in regions where Chaozhou people have immigrated, such as Thailand and Singapore.
