The Chinese call this group Qingshui Miao, meaning "clear water" Miao. This name corresponds to their autonym, Hmong Dlex Nchab (Clear Water Hmong). They also call themselves Black Hmong, but they are not the same group as the local Black Hmong (Hmong Bua) living in the same area.
Historically, the Chinese have viewed the Hmong with contempt, believing them to be "uncivilized barbarians." Visitors to the minority peoples of China, however, have generally found them an extremely warm and hospitable people, often more than the Han Chinese themselves. Father De Mailla's comments on the tribes of Taiwan in the early 1700s still stand true for many of the minorities in China today. De Mailla wrote, "Savages though they may be according to the maxims of the Chinese world, I believe them to be nearer to the true philosophy than a great number of the most celebrated Chinese sages. One never sees among them, even upon Christian testimony, either cheating or quarreling, or robbery or litigation. ... Their dealings are equitable, and they are attached to each other ... they are circumspect in their words, and upright and pure in heart."
The Hmong Dlex Nchab join with other ethnic groups in the area to celebrate several major festivals each year, including the Chinese New Year and Spring festivals.
Most Hmong Dlex Nchab are polytheistic animists. Despite their fear of the spirit world, no Hmong in China are idolaters in the true sense of the word. They worship no idols or images in their rituals.
Generations of Hmong Dlex Nchab have perished without receiving news of the sacrifice of Christ for their sins. The Jinping area is tightly controlled by the Chinese authorities. In 1994, in response to thousands of Hmong Daw coming to Christ through radio broadcasts, the local police arrested 18 church leaders, beat local Christians, and destroyed numerous Bibles and much Christian literature.
