According to statistics, the population of the ethnos group Pa Then is approximately 3,700 people who live primarily in Ha Giang province and Tuyen Quang province.

Despite being of small number and located in remote areas, Pa Then ethnic people still preserve many traditional rituals, among which fire dancing festival is the most original and unique.

The act of dancing on fire is called Po Dinh in Pa Then original language.

The fire dancing festival is usually held after the autumn harvest (anywhere from the middle of the 10th lunar month to the first full moon of the next year). This is also the coldest time of the year./.
