In the zone
An ice skating coach, surnamed Ning, at the China World Shopping Center rink said: "When Ji is ice skating, he is totally in the zone. It's hard not to watch him on the ice.
"After his video went viral, many visitors came here to see him. His passion for ice skating has inspired numerous people to take up the sport.
"Ice skating is accessible to everyone. It is a lifelong healthy activity for all ages and is good for the joints, flexibility, coordination and burning calories," said Ning, 30, a former professional figure skater.
After leaving the figure skating team, Ning, who started to learn ice skating when she was 4, performed in ice dancing shows.
She has coached the sport for three years and most of her students are 5 to 12 years old.
"I've always wanted to share ice skating with more people," she said.
