Liu Hong (洪流) has been competing for 12 years. His best event is the 3×3: a personal-best single of 9.51, set at ZUST Open 2017, puts him in the top 6.1% of the 284,439 people who have ever been ranked in the event, and 2,368th in China. Until February 2008, no official 3×3 solve in the world had been that fast. Across 8 competitions since March 2015, he has put 230 official solves on the record across eight events.

His 3×3 best has come down from 12.78 in March 2015 to 9.51, a 26% improvement. Liu has entered eight competitions, more competitions than 90% 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.
