The 32-year-old Jung has been training with the country's Para Nordic skiers since earlier this month.

"Jung needs time to switch from ice sledge hockey to Nordic skiing," Kim Kwang-rae, a coach for the national Para Nordic skiing team, told South Korean news agency Yonhap. 

"He needs to earn his firearms license for shooting and also has to do exercises to improve his endurance."

Kim, though, believes Jung will quickly learn the sport.

"Jung will probably compete in short distance events in cross-country skiing and sprint events in biathlon," he said. 

"He is known for his pace, so even if he started this sport late, I think he can catch up other athletes quickly."

Jung lost his right leg at the age of five after construction pipes collapsed on him. 

He took up Para ice hockey in 2004. 

At Pyeongcheong 2018, Jung assisted Jang Dong-shin's winner in South Korea's 1-0 win over Italy in the bronze medal match, his country's first in the sport. 

After the Paralympics, Jung said he wanted a new challenge in his career and decided to switch to snow sports. 

In May, he quit his ice hockey team with Gangwon Provincial Government and joined a Para Nordic skiing team run by Changsung Engineering & Construction, where Sin Eui-hyun, the first South Korean Paralympic gold medalist, trains.

"It's a new sport for me, but I want to enjoy it," Jung told Yonhap.

"I will give my best efforts to win a gold medal at the 2022 Beijing Winter Olympics."
