The Summer Olympic Games is the largest comprehensive sports meeting in the world sponsored by the International Olympic Committee. According to the regulations of the International Olympic Committee, the Summer Olympic Games is held every four years and is hosted by different countries or cities in turn. This cycle is called the Olympic cycle, and there is an interval of four years between two summer Olympic Games, which ensures that countries have enough time to prepare and prepare. For example, the last Summer Olympic Games was held in 2020 (due to COVID- 19 epidemic, it was postponed to 202 1 year), and the next Summer Olympic Games will be held in 2024, and so on.
