Murong Du (杜慕荣) has been competing for 9 years. Her best event is the Pyraminx: a personal-best single of 2.12, set at Xi'an Summer 2025, puts her in the top 1.4% of the 129,321 people who have ever been ranked in the event, and 145th in China. Until July 2011, no official Pyraminx solve in the world had been that fast. Across 8 competitions since January 2018, she has put 89 official solves on the record across four events. Solve to solve, her 3×3 times vary about 21% around a typical one, an early reading from 6 counted rounds. Her Pyraminx best has come down from 8.82 in January 2018 to 2.12, a 76% improvement. Murong has entered eight competitions, more competitions than 90% 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.
