Chengjun Chen (陈诚骏) has been competing for 2 years. His best event is the 3×3 one-handed: a personal-best single of 10.76, set at Guangzhou Small Cubes 2025, puts him in the top 1.6% of the 73,695 people who have ever been ranked in the event, and 140th in China. Until July 2011, no official 3×3 one-handed solve in the world had been that fast. Across 7 competitions since July 2024, he has put 191 official solves on the record across six events. Solve to solve, his 3×3 times vary about 11% around a typical one, steadier than 93% of the 35,811 competitors with ten or more counted rounds. His 3×3 best has come down from 8.87 in July 2024 to 7.98, a 10% improvement. Chengjun has entered seven competitions, more competitions than 88% 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.
