Tiancheng Liu (刘天成) has been competing for 8 years. His best event is the Pyraminx: a personal-best single of 4.36, set at Tianjin Summer Open 2018, puts him in the top 9.5% of the 129,321 people who have ever been ranked in the event, and 1,125th in China. Until September 2006, no official Pyraminx solve in the world had been that fast. Across 4 competitions since March 2018, he has put 80 official solves on the record across four events.

Tiancheng has entered four competitions, more competitions than 78% 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.
