Zichen Xia (夏紫晨) has been competing for 3 years. Her best event is the Skewb: a personal-best single of 1.26, set at Guangzhou Special 2026, puts her in the top 0.17% of the 74,164 people who have ever been ranked in the event, and 9th in China. Until October 2015, no official Skewb solve in the world had been that fast. Across 18 competitions since December 2023, she has put 552 official solves on the record across five events.

Her 3×3 best has come down from 10.39 in December 2023 to 6.01, a 42% improvement. Zichen has entered 18 competitions, more competitions than 96% 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.
