Tiancong Lu (陆天聪) has been competing for 7 years. His best event is the Pyraminx: a personal-best single of 2.06, set at Guangzhou Grand Open 2026, puts him in the top 1.3% of the 130,891 people who have ever been ranked in the event, and 141st in China.

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.
