Guangzhi Hou (侯广智) has been competing for 2 years. His best event is the Square-1: a personal-best single of 10.03, set at Tokyo Winter 2025, puts him in the top 6.1% of the 25,272 people who have ever been ranked in the event, and 85th in China. Until August 2010, no official Square-1 solve in the world had been that fast. Across 7 competitions since March 2024, he has put 93 official solves on the record across seven events.

Guangzhi 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.
