Horses are herbivorous animals belonging to the genus Malcoma in the order Quetziformes, and currently exist as two subspecies: domesticated horses and wild horses. According to the natural environmental conditions, as well as differences in appearance and performance, horses can be divided into grassland species, desert species, mountain species, and forest species in their original production areas. Grassland species are distributed in vast grassland areas; Desert species live in dry desert areas; Mountain planting, good at walking on mountain roads; Forest species live in colder forest areas. China domesticated wild horses as livestock as early as 6000 years ago, and for a long time thereafter, horses became one of the main means of transportation.
