Chang Myung-su
Chang Myung-su is a South Korean former figure skater. She competed in the ladies' singles event at the 1972 Winter Olympics.
Chang was taken by her coach Hong Yong-myeong to the 1967 World Championships. There was a controversy around whether Chang could perform due to her age, though the organizers eventually let Chang do a two-minute presentation.
