Introduction to Dulong Niu: There is a kind of cattle growing along the Dulong River. People call it "Gongshan Big-fronted Niu" in its scientific name. Since it originates from the Dulong River Valley, it is also commonly known as "Dulong Niu". . Dulong cattle usually live in groups of five or ten. Under the leadership of the "leader", they live a carefree life in the alpine forests above 2,000 kilometers above sea level. Jackals and wolves in the mountains and forests do not dare to mess with them. Even the tiger, the king of the mountains, has to give them a few points. In the Dulongjiang area, it often happens that cattle are eaten by wild beasts, but Dulong cattle are an exception.
