Long jump is a jumping event in track and field. What are the rules of the game in this project?

The rules of the long jump competition are roughly as follows: 1. The disorderly order of athletes should be decided by drawing lots. 2. If there are more than eight athletes, the top eight athletes with the best three effective results should be allowed to try to jump three times in the market. If the eighth place after the third hop is equal, according to the rules, Article 146 shall be handled three times. When the number of participants is only eight or less, each person can try to jump six times. In the run-up or take-off without take-off, the athlete touches the ground outside the jumper with any part of his body. Jumping from the front or back of the extension line of the jumper wire at both ends of the springboard, and touching the ground outside the landing area during the landing process, the exit position of the landing area is closer to the jumper wire than the nearest contact point in the area. After completing the trial jump, walk back to the area and adopt any somersault posture. When an athlete runs up, it is not a foul to run out of the sign line of the run-up lane at any position. When measuring the results, we should measure the jump shot or the extension line of the jump shot from the nearest point where any part of the athlete touches the ground, and the measuring line should be perpendicular to the jump shot or its extension line. Because of smoking addiction, each athlete's best jump test results, including the coordination results caused by the equal results of the first place in the final ranking competition, are the final decision. The length of the run-up lane should be at least 40 meters, and the length of the run-up lane should be at least 45 meters. The minimum width of the run-up lane is1.2m and the maximum width is1.2m.. A white line with a width of 5 cm should be drawn in five meters, which is helpful for athletes to run up and take off. If this mark is not provided, athletes can use adhesive tape, but it is forbidden to mark the position of this runway with chalk or other similar indelible substances. The springboard is a sign of take-off. It should be buried underground, on the surface of the upper edge, approach road and landing area. The edge of the springboard near the landing area is called other lines, and the jumper should put a plasticine display board to facilitate the referee's judgment.
