3×3 · top 2.1% of 284,439 all-time · competing since May 2025 · 2025NAZH01
Zheng Na (南征) has been competing for a year. His best event is the 3×3: a personal-best single of 7.55, set at Hefei Open 2025, puts him in the top 2.1% of the 284,439 people who have ever been ranked in the event, and 737th in China. Until July 2008, no official 3×3 solve in the world had been that fast. Across 4 competitions since May 2025, he has put 89 official solves on the record across three events. Solve to solve, his 3×3 times vary about 14% around a typical one, an early reading from 8 counted rounds. His 3×3 best has come down from 8.56 in May 2025 to 7.55, a 12% improvement. Zheng has entered four competitions, more competitions than 78% 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.
