Yak not only has strong carrying capacity and pulling force, but also has edible meat, drinkable milk and usable fur. Cow dung can be used as both fertilizer and firewood. Butter extracted from yak milk is the main edible oil for people in plateau areas. Yak skin is tough, shiny and wear-resistant. Yak hair can be spun into fine yak hair. The rope twisted with cow hair is elastic and shiny, strong and durable, and the tent made of it has strong cold resistance, which is still an important shelter for herders. The "hair duster" made of yak tail is fluffy and durable, and has strong dust removal ability, especially the white tail is more precious.
Yak is full of treasures. Tibetan people can't live without it. People drink yak milk, eat yak meat and burn yak dung. Its wool can be used to make clothes or tents, and its skin is a good tanning material. Yak is known as "the ship on the plateau". It can be used not only for farming, but also as a means of transportation on the plateau. Yaks also have the ability to find their way. They are good at taking dangerous roads and swamps, and can avoid traps and choose their own roads, which can be used as guides for tourists.
