Yumeng Zhou (周雨萌) has been competing for 9 years. Her best event is the 3×3 blindfolded: a personal-best single of 33.99, set at China Championship 2019, puts her in the top 5.2% of the 12,178 people who have ever been ranked in the event, and 93rd in China.

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.
