Lu's Spring and Autumn Annals once recorded that "the meat is delicious, and the meat is delicious". It can be seen that yak meat is the best meat from ancient times to the present, especially in autumn, it is the delicious food for diners in the capital to eat yak meat warmed up on the Qinghai-Tibet Plateau. Yaks live in areas thousands of meters above sea level all the year round. Many wild medicinal species such as Fritillaria and Cordyceps grow in these areas. Yaks often eat these medicinal materials, and their meat is delicious. After killing, they can be fried in brown sauce, chaotic or dried in the sun for thousands of bars, which has a unique taste.
