The domestication, raising, servitude, and extensive use of yaks, as well as their spiritualization and artisticization, are important foundations and supports of Tibetan culture, and are also a legendary story in the grand chapter of human civilization. Studies have shown that the Qinghai-Tibet Plateau, with an altitude of 2,000-5,000 meters, is the main habitat of yaks on the earth. The earliest evidence of yak domestication and use comes from the Qugong site in Lhasa, which is nearly 4,000 years old. The remains of animals unearthed from the site include sheep, yaks, and dogs. From this, it can be inferred that Tibetan sheep and yaks were the main source of meat for the villagers of Qugong, and yaks and sheep were already widely raised at that time. The Qugong domestic yak is small in size and has thin horns. It is the earliest domestic yak known to date. This also shows that the model of combining agriculture and animal husbandry appeared very early in the Tibetan region, which is a great contribution of the Tibetan ancestors to ancient animal husbandry. Of course, the successful domestication of yaks on the plateau may be earlier than the time when the Qugong people lived. A large number of cattle bones were unearthed at the Qamdo Karo site, which is four or five thousand years old. In the book Qamdo Karo, although it was only identified as Bovidae, without mentioning the species, it proved that early humans used cattle and had a close relationship with cattle. In the 1950s, small pottery similar to the image of yaks was found at the Dalitaliha site of the Ruomuhong site in Dulan, Qinghai, which was equivalent to the Western Zhou Dynasty in the Central Plains. This shows that humans have long placed cultural connotations on yaks. In 2003, at the Chaxiutang sacrificial site in Nagqu, Tibet, archaeologists discovered Tibetan characters and some religious symbols written in ink on the skull of a yak. According to research, the content of the Tibetan characters in ink should be a witchcraft, and the font is similar to the Tibetan font that transitioned from regular script to cursive script. Scientific speculation is that the sacrificial site dates from the 9th to the 11th century, and it is a relic of sacrificial or witchcraft activities of the primitive religion of Tibet, Bon. Its discovery also illustrates the relationship between yaks and ancient Tibetan folk primitive religions, and the spiritual connotations that the Tibetan people have endowed on yaks. Unfolding the magnificent picture of nature and science, humanities and history, spirit and art on the Qinghai-Tibet Plateau, in the beautiful and sacred snow-covered holy land, plateau humans and yaks are integrated with nature, advocating all things in nature, obeying the laws of nature, creating ecological civilization, living in harmony with thousands of creatures, sharing weal and woe, and accumulating the quiet and extraordinary cultural heritage and calm and pure human character in the constantly alternating historical process. As the production partner and source of wealth of plateau humans, yaks have always been on the high and vast Qinghai-Tibet Plateau. Generation after generation, they have been the road sign model for plateau humans to move forward courageously, and constantly provide them with spiritual pursuits and survival motivation. Not only does it nourish the unique temperament of plateau people to endure hardships, be strong and unyielding, and be optimistic and enterprising with its innate perseverance, but it also shows the snow-covered people the lofty ideal of achieving the past and future lives in their open and clear minds with its lofty physique like a snow-covered lion, its fiery temperament and its generous tolerance like the heaven and earth, bringing warmth and enthusiasm to the strong people who have lived in the cold plateau for generations, soothing their hearts, invigorating their spirits and broadening their horizons. In order to further spread the plateau civilization and yak culture and deepen people's understanding of the plateau boat, this magazine specially publishes this issue of yak album on the occasion of the opening of the Tibet Yak Museum to show our infinite gratitude to yaks and yak spirits. The 10th Panchen Lama once said: "Without yaks, there would be no Tibetans." A Tibetan folk proverb also says: "Wherever there are Tibetans, there are yaks." Yak, a life and cultural community of the Tibetan Plateau. Yaks began to live in this vast land long before humans did, and together with humans, they have guarded this holy land. This is why plateau humans have respected yaks for generations and have worked together to accumulate plateau civilization. For plateau humans, yaks are eternal ancestors, grandparents, parents, brothers and sisters, children, friends and partners, and neighbors and relatives. They are a life and cultural community that has naturally formed in the common actual production and life for tens of millions of years. Yapozhang, the palace of yaks Yaks have been accompanying the Tibetan people for thousands of years, and have done their best to help the Tibetan people with clothing, food, housing, transportation, transportation, burning, and farming. The existence and use of yaks involve politics, education, business, war, entertainment, medicine, material supplies, etc. on the Tibetan Plateau, which have profoundly affected the spiritual character of the Tibetan people and all aspects of their material life, thus forming a unique plateau yak culture. In order to preserve the cultural evidence of yaks and spread the knowledge of yak culture, the first national-level museum with yaks as the theme in China and even in the world will be opened for trial operation on May 18, 2014, the International Museum Day. Wild yaks, the silent ones in the wilderness Almost half of the world's wild yaks live in the Qiangtang National Nature Reserve in Tibet. In various versions of stories about encounters with wild yaks, wild yaks are frightening because of their violent and aggressive personalities. Dr. George Schaller's description from a biological perspective represents deep concern: "Wild yaks symbolize the vast and boundless Qiangtang and are a symbol of this plateau. At the same time, they also represent the difficult situation of wild animals on the Qinghai-Tibet Plateau."
