Ziyu Liu (刘子鱼) has been competing for a year. His best event is the 4×4: a personal-best single of 21.90, set at Beijing Autumn Rivalry 2026, puts him in the top 0.19% of the 85,040 people who have ever been ranked in the event, and 25th in China. Until October 2015, no official 4×4 solve in the world had been that fast. Across 2 competitions since August 2025, he has put 45 official solves on the record across four events. His 4×4 best has come down from 28.61 in August 2025 to 21.90, a 23% improvement. Ziyu has entered two competitions.

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.
