The San Chay people (Vietnamese: Người Sán Chay; also called Sán Chỉ) live in Tuyên Quang Province of the Northeast region of Vietnam, as well as some nearby provinces.

The Pinghua language is a form of Chinese language.

Many live in remote areas, using slash-and-burn agriculture because those areas are not flat enough for paddy rice production.

[4] They sing sình cồ (love songs) and celebrate the Slếch thlin mảy festival (New Rice festival).

The San Chay people are related with the Shanzi People in Guangxi, China.
