Zilun Huang (黄子伦) has been competing for 2 years. His best event is the Clock: a personal-best single of 3.61, set at Taizhou Open 2025, puts him in the top 1.7% of the 32,048 people who have ever been ranked in the event, and 21st in China. Until July 2018, no official Clock solve in the world had been that fast. Across 12 competitions since June 2024, he has put 258 official solves on the record across six events.

His 3×3 best has come down from 14.33 in June 2024 to 8.53, a 40% improvement. Zilun has entered twelve competitions, more competitions than 94% 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.
