Jiaming Zhang (张家铭) has been competing for a year. His best event is the 3×3: a personal-best single of 7.43, set at Beijing Only 3x3 2025, puts him in the top 1.9% of the 284,439 people who have ever been ranked in the event, and 664th in China. Until July 2008, no official 3×3 solve in the world had been that fast. Across 5 competitions since September 2025, he has put 125 official solves on the record across nine events.

His 3×3 best has come down from 8.98 in September 2025 to 7.43, a 17% improvement. Jiaming 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.
