About Đàn Tính (Tính Tẩu)
The đàn tính, or tính tẩu, is a stringed musical instrument from tianqin Chinese: 天琴; pinyin: Tiān qín of Zhuang people in China, imported to Vietnam by the Tay people of Lạng Sơn Province in Vietnam. Although "tinh tau" originated as a Tay word, both names are used in Vietnamese.
