Mu Tiezhu, a former member of Bayi Basketball Team, has a condition called 'acromegaly' (a disorder that results from excess growth hormone).
He was often compared with Sun Mingming, because both of them have acromegaly, and could slam dunk without their feet leaving the ground. Acromegaly is a disorder that results from excess growth hormone (GH) after the growth plates have closed. As a member of Bayi Basketball Team, Mu still held the highest score of 81 points in a game, and beat the 1978 NBA champion Washington Bullets twice in April, 1979.
