Deer chess, called "Baogen Jirige" in Mongolian, originated in the 7th and 8th centuries. It is one of the traditional entertainment activities of the Mongolian people. In addition to horse racing, camel fighting and dancing, the entertainment activities of ancient nomads also included deer chess and other entertainment activities. Ancient deer chess rock paintings have been found in the ancient Yinshan rock paintings and the Ulanqab grassland. The deer chess board on the rock painting is square, with five vertical and horizontal lines, crossing into 25 points. Mongolian deer chess is simple and easy to learn, enlightening wisdom, deeply loved by people, and has been passed down for more than a thousand years. The chess pieces of the Mongolian deer chess of Qian Gorlos are divided into two types: deer (called "Bao Ge" in Mongolian) and dog (called "Nao Hai" in Mongolian). There are mountains (called "Ula" in Mongolian) and plains (called "Tara" in Mongolian) on the chessboard. According to the number of "mountains" on the chessboard, the size of "plains", and the number of chess pieces, deer chess can be divided into two deer and twenty-four dogs and four deer and sixty-four dogs. In the Guoerlos region, the deer chess with two deer and twenty-four dogs is widely circulated among the people. The Guoerlos deer chess board is: a square with five vertical and horizontal lines and six diagonal lines, which intersect to form twenty-five points. At both ends of the central vertical line, there is a triangular flat-topped "yuan" and a diamond-shaped pointed "shan", with cross lines inside, which also form several intersections. The two players each hold a "deer" or a "dog", which is similar to Chinese chess. Before the game, the pieces are placed first. The layout is to place the two "deer" at the entrance of the "shan" on both sides and the eight "dogs" at the eight points in the center of the chessboard. The traditional rules are mainly: "deer" can move on the entire chessboard, while "dogs" can only move in the large square area and cannot enter the "shan". Deer and dogs can only move one step at a time, and can move in a straight line or a diagonal line. When playing, the player holding the "deer" moves first. The main point is "the deer jumps and eats the dog, and the dog surrounds the deer", that is, the person holding the "dog" must circle the "deer", and the person holding the "deer" must eat all the "dogs" and not be circled by the "dog". If the "deer" is circled by the dog, the person holding the "deer" loses the game; if the dog cannot surround the "deer", the person holding the "dog" loses the game. In the past, the deer chess in the noble families of the Mongolian in Gorlos had very delicate wooden deer and dog chess pieces, and the chessboard was painted on a wooden board. When ordinary people play chess, they often use the ankle bones of cattle and sheep and small stones or copper coins, rice grains as chess pieces, and the chessboard is painted on paper or sand, so that people can play chess anytime and anywhere. In the Mongolian villages in the former Gorlos, people often gather together in their spare time to play deer chess. Deer chess is one of the typical Mongolian folk chess arts, with a long history and strong mass participation. Deer chess reflects the intelligence and wisdom of the Mongolian people. It has special academic value in traditional wisdom-related competitive and entertainment projects, and is of great significance to the study of Mongolian history, folklore, and society. (Note: When the project was applied for the third batch of national lists, the original project name "Mongolian Deer Chess" was changed to "Qian Gorlos Mongolian Deer Chess".)
