The guzheng, also spelled gu zheng or gu-zheng (Chinese: 古箏; pinyin: gǔzhēng) or zheng (箏) (gu-, 古 means "ancient") is a traditional Chinese musical instrument. It belongs to the zither family of string instruments.

 

The guzheng is the parent instrument of the Japanese koto, the Mongolian yatga, the Korean gayageum, and the Vietnamese đàn tranh. The parent instrument of the guzheng is the se.[citation needed]

 

The guzheng should not to be confused with the guqin (another ancient Chinese zither but without bridges).
