Kaikai Xuan (轩凯凯) has been competing for 9 years. His best event is the 3×3 one-handed: a personal-best single of 13.03, set at Xiamen Autumn 2019, puts him in the top 4.5% of the 73,695 people who have ever been ranked in the event, and 394th in China.

Reading this page: a single is one solve's time · an average is the middle three of five solves, best and worst discarded · a PB is a personal best · a DNF (did not finish) is an attempt with no valid result: a popped piece, an unsolved face, an over-limit memorisation · top X% compares against everyone ever ranked in that event, which is fairer than raw rank because event pools differ tenfold.
