"My heart is very young" the table tennis pioneer told Olympic Channel, as she looks ahead to another major tournament appearance. Before moving to Luxembourg... in the 1980s, Ni won two doubles world titles with China in Tokyo. She'll return to the Japanese capital in 2021, having qualified for her fifth Olympics representing the European nation. Ni turns 58 in July, making her the oldest table tennis player in Olympic history, and she could be the oldest athlete at the Games in any sport. The veteran table tennis player relishes her many nicknames: Mummy, sister, auntie, teacher, coach, and shares what she's most looking forward to during this next career landmark.
