Kweon won the silver medal in the men's halfpipe competition at the Asian Winter Games in Sapporo, Japan, in February. The 20-year-old said he is studying the moves of Japanese snowboarder Taku Hiraoka, who won bronze at the 2014 Sochi Winter Olympics.

 "He is an Asian snowboarder and also a regular-stance rider like me, so there are lots of things to learn from him," Kweon said. "Hiraoka executes skills that are two or three levels higher than mine. I would say the difficulty of our technique is similar, but he goes up higher in the air and makes clean landings."

Kweon, who started snowboarding around age seven, said he is satisfied with facilities at PyeongChang, and expected to have the home field advantage.

"I've heard from many foreign athletes at the Olympic test event that the facilities in PyeongChang are the best," he said. "I didn't really expect the halfpipe facility to be that good, but after riding it, I felt it suits me."

Lee, who will compete in both slopestyle and big air events at the Olympics, said he also has no worries on venue conditions. The 17-year-old, currently a student at Cheongmyeong High School in Suwon, Gyeonggi Province, last year competed at PyeongChang's big air test, finishing 34th.

"The size of the man-made slope is really big and it's steep, so it isn't easy," he said. "But it's the best facility that you don't have to worry about speed."

Lee, who started snowboarding after watching the 2010 Vancouver Winter Games, said he has been practicing to improve rotation moves.

"Last season, I could only make three rotations, but now I can execute four rotations in the air," he said. "Snowboarding is a really entertaining discipline, so I'm sure fans will know the essence of the sport at the Olympics." (Yonhap)
