After starting, the skaters accelerated, slid up and down on the almost vertical and cold groove wall, "walked out of the groove" and flew, flipping and grabbing the board in all directions in the air. After each roller skating, the referee will score according to the range, difficulty, change and execution of the players' actions, and take the highest round of scores to rank, go big or go home! Such a mechanism also encourages players to challenge higher difficulties.
In slope obstacle skill and U-shaped field skill, players will play twice in the qualifying round, and the one with higher score is the best result. The final 12 player will have three rounds of competition, with the best result as the final result, which also means that the suspense of the competition will remain until the end. In the U-shaped venue skill competition of this Winter Olympics, China team won eight places in the Winter Olympics, among which Gu Ailing, a talented girl of the women's team, was the favorite to win the championship. Before the Winter Olympics, she swept all the U-shaped World Cup competitions this season. However, Kathy Sharp, a Canadian who won the last Winter Olympics, Kelly Hildaru, an Estonian who is only one year older than Gu Ailing, and Tess Ledex, a Frenchman, are invincible enemies.
David Wise, the two-time men's champion in the 20 14 and 18 Winter Olympics, Alex Ferreira, the last runner-up and Aaron Blunck, the two-time world champion, led the all-star team of the US team. Apart from infighting, there was also a sniper by Nico Porteous, the defending world champion.
