The video shows a group of yaks with saddles on their backs, walking through a forest. The yaks are carrying baskets and bags on their backs. The forest is lush and green, with tall trees and a clear path for the yaks to follow. The yaks are walking in a line, with one leading the way and the others following behind. The saddles on the yaks are made of leather and are secured with ropes. The baskets and bags are made of woven material and are filled with supplies. The yaks are walking at a steady pace, and their hooves are making a soft thudding sound as they hit the ground. The video is shot during the day, and the sunlight filters through the trees, casting dappled shadows on the ground.
