Kai Bian (卞凯) has been competing for 7 years. His best event is the 3×3: a personal-best single of 7.60, set at Beijing Only 3x3 2025, puts him in the top 2.1% of the 284,439 people who have ever been ranked in the event, and 770th in China. Until July 2008, no official 3×3 solve in the world had been that fast. Across 8 competitions since August 2019, he has put 161 official solves on the record across five events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 74% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 12.91 in August 2019 to 7.60, a 41% improvement. Kai has entered eight competitions, more competitions than 90% of everyone who has ever competed.

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.
