Muzi Li (李穆子)
2×2 · top 1.0% of 186,767 all-time · competing since November 2025 · 2025LIMU02
Muzi Li (李穆子) has been competing for 9 months. His best event is the 2×2: a personal-best single of 1.19, set at Beijing Winter 2026, puts him in the top 1.0% of the 186,767 people who have ever been ranked in the event, and 112th in China. Until November 2008, no official 2×2 solve in the world had been that fast. Across 5 competitions since November 2025, he has put 87 official solves on the record across four events. Solve to solve, his 3×3 times vary about 9% around a typical one, an early reading from 8 counted rounds. That figure sets aside his 2 DNFs. His 3×3 best has come down from 15.09 in November 2025 to 8.20, a 46% improvement. Muzi 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.
