Black yak means black yak and chinese is translated into blyak. Specialized research and production was created in 1973, with international specialized outdoor sports items under the umbrella of the korea eastward group, which is equipped with outdoor clothing, such as mountain climbing, camping and rock climbing. The yaks are species specific to the tibetan plateau and live at very high altitudes with very poor natural environments. It has a cold-resistant, heavy-duty character. The tibetan people, who live in the tibetan highlands, live in clothing and food, and they cannot leave their yaks anywhere. Long yak hairs can be woven into thick blankets and tents; yak milk can be made of cheese and soufflés; soufflé tea made of soufflé is an essential daily drink for the tibetan people. She helps the tibetans to withstand the cold winds and severe aerobics in the himalayas; in the cold and cold areas of the valleys, yak manure is also used by pastoralists as a fuel for burning and heating; and yaks not only carry supplies for the local people, but also for the distant climbers and explorers, who carry equipment for the snow canoes. Through the spirit of the yaks, in 1996 the dongjin group created a brand of outdoor sports items with deep connotations -- black yak, praying for the black yak brand, just as the clan protector of ancient tibetan myths, the yak, protects every exterior explorer. As an outdoor brand created and designed by mountain climbers, black yak embraces the customer philosophy of "freedom to do what he wants" and adheres to the quality concept of "only providing the customer with a product that has been tested under the most restrictive conditions", pursues product performance and functionality and pursues design that is closer to the needs of users in outdoor activities。
