Ni said the average age of the members is 50, with the oldest, a woman named Wang, age 57.

"The group includes both retirees and office workers, but we all skateboard every day," Ni said.

At first, Wang said she had concerns, fearing she could fall and break a bone.

"But learning to skateboard is a process that takes you from nervousness and fear to relaxation and control. I was able to skateboard easily after a week of practice," Wang said.

She said she is now trying to learn new skills to improve her style.

"In addition to health and happiness, skateboarding has made me confident and makes me feel younger," she said.

Wang joined the team at the beginning of April after seeing Ni's expertise with the board.

"And also because I wanted to have a try," she added.
