Bohan Zhuang (庄博涵) has been competing for 13 years. His best event is the 3×3: a personal-best single of 8.80, set at Shenzhen Open 2023, puts him in the top 4.4% of the 288,433 people who have ever been ranked in the event, and 1,720th in China. Until May 2008, no official 3×3 solve in the world had been that fast. Across 6 competitions since October 2013, he has put 109 official solves on the record across five events.

His 3×3 best has come down from 24.98 in October 2013 to 8.80, a 65% improvement. Bohan has entered six competitions, more competitions than 86% 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.
