Yubin Du (杜宇斌) has been competing for 8 years. His best event is the 3×3: a personal-best single of 8.11, set at Shenzhen Open 2023, puts him in the top 3.0% of the 284,439 people who have ever been ranked in the event, and 1,086th in China. Until July 2008, no official 3×3 solve in the world had been that fast. Across 4 competitions since July 2018, he has put 40 official solves on the record across two events.

Yubin 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.
