4×4 · top 10.0% of 85,040 all-time · competing since May 2010 · 2010LIUB02
Bojiang Liu (刘柏江) has been competing for 16 years. His best event is the 4×4: a personal-best single of 38.13, set at Beijing Summer 2025, puts him in the top 10.0% of the 85,040 people who have ever been ranked in the event, and 1,077th in China. Across 8 competitions since May 2010, he has put 233 official solves on the record across six events. Solve to solve, his 3×3 times vary about 8% around a typical one, steadier than 99% of the 36,406 competitors with ten or more counted rounds. That figure sets aside his 5 DNFs. His 3×3 best has come down from 13.59 in May 2010 to 11.71, a 14% improvement. Bojiang 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.
