Kaichen Luo (罗凯辰) has been competing for 2 years. His best event is the 3×3: a personal-best single of 8.83, set at Beijing Autumn Rivalry 2026, puts him in the top 4.5% of the 288,433 people who have ever been ranked in the event, and 1,745th in China. Until May 2008, no official 3×3 solve in the world had been that fast. Across 3 competitions since August 2024, he has put 44 official solves on the record across three events.

Kaichen has entered three competitions, more competitions than 69% 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.
