When was the last time you did something fun with your parents? For 56-year-old Zheng Li from Siping in northeast China's Jilin Province, the answer may be earlier today. Zheng has spent the past 20 years playing sports with his 82-year-old mother, Ju Shuqing. The two came up with various ways of playing table tennis, badminton, Frisbee and many other sports. Sports have helped Ju stay healthy and feel loved with her son by her side all the time.
