The Olympic five-ring symbol is made up of five Olympic rings nested from left to right, which can be monochrome, blue, yellow, black, green and red. The original explanation was that the five colors represented the colors of national flags, and later the five rings with different colors were interpreted as symbols of the five continents.
The Olympic flag is 3 meters long and 2 meters wide with a white background, which symbolizes purity. Blue, yellow, black, green and red are interlocking. 1920, the Olympic flag flew for the first time at the Summer Olympic Stadium in Antwerp. After this Olympic Games, the Belgian Olympic Committee presented the same national flag to the International Olympic Committee. After that, the flag was handed over from the previous host city to the current host city at the opening ceremony and kept by the current host city. During the competition, only substitutes were hung in the main stadium. 1952, Oslo, Norway presented the flag of the Winter Olympics to the International Olympic Committee in the same way as the Summer Olympics.
1In June, 979, the International Olympic Committee officially announced the meaning of the Olympic flag and the five-ring symbol: it symbolizes the unity of the five continents and the gathering of athletes from all over the world in the Olympic Games with fair and frank competition and friendly spirit.
