Sijun Meng (孟思竣) has been competing for 3 years. His best event is the 3×3: a personal-best single of 8.24, set at Dalian Open 2024, puts him in the top 3.2% of the 284,439 people who have ever been ranked in the event, and 1,196th in China. Until July 2008, no official 3×3 solve in the world had been that fast. Across 8 competitions since December 2023, he has put 120 official solves on the record across three events.

His 3×3 best has come down from 10.00 in December 2023 to 8.24, an 18% improvement. Sijun 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.
