‘Sài mǎ’ literally means ‘race horse’—‘sài’ (赛) means ‘to compete’ or ‘contest’, and ‘mǎ’ (马) means ‘horse’. Together, the term refers to the sport of horse racing, where jockeys ride horses in timed competitions over set distances. It is a compound noun formed by combining an action-related character with an animal, reflecting the competitive nature of the activity.

Horse racing is a popular spectator sport in many parts of China, especially in regions with strong equestrian traditions like Inner Mongolia and Xinjiang. It also appears in cultural contexts such as festivals, tourism promotions, and media coverage of international events. While ‘sài mǎ’ specifically denotes the sport itself—not individual horses or races—it can appear in phrases like ‘sài mǎ chǎng’ (racecourse) or ‘sài mǎ jié’ (Horse Racing Festival). The word carries neutral formality and is used in both spoken and written Chinese.
