Shijia Xu (徐世嘉) has been competing for a year. His best event is the 2×2: a personal-best single of 2.01, set at Hefei Open 2025, puts him in the top 4.8% of the 186,767 people who have ever been ranked in the event, and 665th in China. Until February 2008, no official 2×2 solve in the world had been that fast. Across 4 competitions since July 2025, he has put 45 official solves on the record across two events. Solve to solve, his 3×3 times vary about 20% around a typical one, an early reading from 6 counted rounds. His 3×3 best has come down from 12.04 in July 2025 to 9.66, a 20% improvement. Shijia has entered four competitions, more competitions than 78% 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.
