Tianzuo Du (杜天佐) has been competing for 6 years. His best event is the 7×7: a personal-best single of 1:56.50, set at Singapore Max 2024, puts him in the top 0.42% of the 14,450 people who have ever been ranked in the event, and 9th in China.

Tianzuo 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.
