Zeng Cheng (程锃) has been competing for 10 years. His best event is the 4×4: a personal-best single of 33.82, set at Xuzhou Zenith 2026, puts him in the top 5.7% of the 83,917 people who have ever been ranked in the event, and 566th in China. Until November 2010, no official 4×4 solve in the world had been that fast. Across 10 competitions since April 2016, he has put 202 official solves on the record across five events.

Zeng has entered ten competitions, more competitions than 92% 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.
