The traditional tent weaving technique (Baqing ox-hair tent weaving technique) is a national intangible cultural heritage. Black tents are usually made of tent material woven from the long hair of yaks, which is called "Ri Ya". Making coarse felt is a time-consuming and laborious job. First, the thick ox hair must be cut from the yak, then the ox hair must be combed flat, then the combed ox hair must be twisted into thread, and finally woven into shape. When setting up, pull the Qiongta (pull rope) at the four corners of the top of the tent to a distance and tie it to the nailed wooden pegs. Then, a wooden pole is set up in the tent as a crossbeam to support the roof, and then the two ends of the crossbeam are supported by pillars. Then adjust the tension of the pull ropes around to fix the tent, and finally nail the small rope buckles at the bottom of the four walls of the tent with pegs to tighten and fix the four walls of the tent. On May 24, 2021, the traditional tent weaving technique (Baqing ox-hair tent weaving technique) applied by Nagqu City, Tibet Autonomous Region was approved by the State Council to be included in the fifth batch of national intangible cultural heritage representative projects.
