This study, based on a trip to the Yushu Tibetan Autonomous Region of Qinghai Province, China in August 2018, focuses on the tradition of using wooden nose-rings for managing draught yaks and yak-cow hybrids, still practiced in Tibet. The materials and technology for manufacturing this tool are described, and measurements are provided. I describe variants of the traditional yoke and plow (ard) system used in conjunction with a nose-ring and identify several variants of nose-ring, distinguished by the style of terminus. I investigate seasonality of use, method of piercing, age of animals at piercing, techniques for managing single animals and draught teams, as well as nose-ring durability and advantages of wooden vs. rope forms. Based on a comprehensive comparative historical analysis of materials from Yushu, I suggest that Tibetan ancestors, who had moved there from the northeast in the second half of the 1st millennium BC, introduced wooden nose-ring technology.
