Haobin Zou (邹皓彬) has been competing for 6 years. His best event is the 2×2: a personal-best single of 1.76, set at Jiangmen Open 2025, puts him in the top 3.4% of the 186,767 people who have ever been ranked in the event, and 439th in China. Until February 2008, no official 2×2 solve in the world had been that fast. Across 7 competitions since February 2021, he has put 97 official solves on the record across four events. Solve to solve, his 3×3 times vary about 15% around a typical one, an early reading from 8 counted rounds. His 3×3 best has come down from 17.96 in February 2021 to 10.20, a 43% improvement. Haobin 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.
