Hu Diefei is 62. Her first contact with roller skating was in 2018. In just four years, she jumped from a student to a teacher and is now the roller skating ballroom dance teacher of the Gutianqiao Branch of the Hubei Pioneer Roller Skating Team. "I once rode across half of China and spent 10 years in the Wuhan Winter Swimming Team. When I was about to retire, I found a new hobby. I came out every day to skate with my old friends. I was very happy," she says. They are intensively rehearsing their new piece Blue Sky Dream, which will be performed at the 10th anniversary celebration of Wuhan Roller Skating Association.
