Chengxun Yang (杨承勋)
Square-1 · top 2.2% of 25,662 all-time · competing since July 2025 · 2025YANG50
Chengxun Yang (杨承勋) has been competing for a year. His best event is the Square-1: a personal-best single of 7.35, set at Jiajiang Open 2026, puts him in the top 2.2% of the 25,662 people who have ever been ranked in the event, and 30th in China. Until May 2014, no official Square-1 solve in the world had been that fast. Across 6 competitions since July 2025, he has put 121 official solves on the record across four events. Solve to solve, his 3×3 times vary about 12% around a typical one, steadier than 62% of the 36,406 competitors with ten or more counted rounds. That figure sets aside his 3 DNFs. His 3×3 best has come down from 12.46 in July 2025 to 8.52, a 32% improvement. Chengxun has entered six competitions, more competitions than 86% 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.
