Mujin Xu (徐沐槿) has been competing for 2 years. Her best event is the 3×3: a personal-best single of 9.88, set at Shenzhen Nanshan Open 2024, puts her in the top 7.1% of the 284,439 people who have ever been ranked in the event, and 2,767th in China. Until May 2007, no official 3×3 solve in the world had been that fast. Across 4 competitions since March 2024, she has put 50 official solves on the record across three events.

Mujin 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.
