The Mongols call meat food "Ulan Yide", which means red food. Meat is the main food for raising the Mongolian people. According to the "Black Tartar Story", the Mongolians' meat mainly comes from hunting products and domestic livestock. Hunting animals include hares, deer, gazelle, etc. The main food for daily consumption is domestic livestock, mainly sheep, followed by cattle. It is not a large-scale banquet, and horses are generally not killed because they consider horses to be more noble animals. "Suiyuan Tongzhi Manuscript" says: "The custom is to avoid eating horse meat. This is because in the early years, people were assigned to the military, and their horses made great contributions, so they used their strength not to eat their meat.". Of course, this is also related to the Mongolian traditional concept of loving horses. This eating habit has lasted for nearly a thousand years, not only forming the unique customs of this nation, but also having a certain impact on other nomadic ethnic groups. The Mongolian people mainly eat small livestock, mainly sheep, because sheep are the main livestock, and the others are obtained by hunting. The Mongolian people believe that eating hot animals is good for the human body, because cattle and horses are relatively large. Livestock is not as convenient as sheep to slaughter, and it plays an important role in transportation, so horses are usually slaughtered during sacrifices. Mutton is the herdsmen’s favorite meat. During their long life, the herdsmen have accumulated rich life experience and produced a series of mutton delicacies such as roasted whole lamb and hand-chopped meat.
