Jiahui Liu (刘嘉晖) has been competing for 7 years. His best event is the 3×3: a personal-best single of 10.54, set at Yunnan Open 2025, puts him in the top 9.1% of the 284,439 people who have ever been ranked in the event, and 3,549th in China. Until August 2006, no official 3×3 solve in the world had been that fast. Across 3 competitions since May 2019, he has put 30 official solves on the record across one event. Solve to solve, his 3×3 times vary about 10% around a typical one, an early reading from 6 counted rounds. His 3×3 best has come down from 15.29 in May 2019 to 10.54, a 31% improvement. Jiahui has entered three competitions, more competitions than 69% 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.
