At 60 years of age, Liu Na has always loved sports. However, in recent years, every time she goes hiking, she has increasingly felt that her knees and legs are no longer as strong as when she was younger.
Not long ago, during a trial experience event at Duishan Park in Tianjin, she put on an exoskeleton device for the first time.
"I was a little worried at first. I thought this thing would be particularly heavy," Liu said.
But after she put it on and started climbing, she quickly found that her legs seemed to be gently lifted by a mild force.
