The red and blue circles in curling are to determine which curling is closer to the center of the circle, similar to the target in shooting.

Curling, also known as curling, is a throwing competition on the ice in teams. The Winter Olympics includes both men's and women's events. Curling is a sport that combines skill and wisdom. Each game is played by two teams, and each player has two opportunities to throw pots, alternately throwing pots at first base, second base, third base and fourth base.

Curling is widely regarded as one of the oldest team sports in the world. Curling originated in the cold northern European winter, and throwing stones on the ice is a pleasant pastime. Early enthusiasts played on frozen lakes and ponds. Curling first appeared at the Universiade and the Asian Winter Games in 2003.
