Ziyi Cong (丛子弋) has been competing for 10 years. His best event is the 3×3 blindfolded: a personal-best single of 47.32, set at Guangdong Open 2018, puts him in the top 9.0% of the 12,178 people who have ever been ranked in the event, and 139th 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.
