Jiashu Zhou (周佳澍) has been competing for 2 years. His best event is the 3×3: a personal-best single of 5.72, set at Xi'an Open 2026, puts him in the top 0.34% of the 284,439 people who have ever been ranked in the event, and 137th in China. Until June 2011, no official 3×3 solve in the world had been that fast. Across 5 competitions since August 2024, he has put 102 official solves on the record across four events.

His 3×3 best has come down from 8.16 in August 2024 to 5.72, a 30% improvement. Jiashu has entered five competitions, more competitions than 83% 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.
