What determines the first hand and the last hand in curling competition?

At the beginning of the game, each side throws a pot. The pot thrown by the opponent is perpendicular to the T line, that is, the center line of the track base camp, and the distance (LSD) is close. Which side has the right to choose whether it is the first hand or the second hand. The preferred party will generally choose second-hand, because second-hand generally has certain advantages.

Whoever scores in the first game is the first player in the second game, but if the score is 0: 0, the order of the next game remains unchanged.

The curling competition is a game of 10. If the ninth inning is the back hand and no one scores in this inning, then the back hand is in the 10 inning or the back hand. If a team scores, the one who doesn't score is the back hand of the tenth inning.

If the score is tied at 10, overtime will be played, and the first ten games will be postponed in overtime, that is, the winner of the tenth game will be the first.
