Six-year-old Chinese speedcuber Lian Yunzhi has twice broken the women’s Rubik’s Cube average world record at World Cube Association-certified competitions in Wuhan and Guangzhou, according to state broadcaster CCTV.
The Chengdu native recorded an average solving time of 4.52 seconds and was described by CCTV as the first female speedcuber to average below 4.5 seconds.
Lian has reportedly learned more than 1,300 solving algorithms through daily practice.
Her mother said solving the cube can help develop concentration, memory, logical thinking and spatial awareness, while also encouraging a balanced approach to competition.
Lian’s growing collection of trophies is displayed at home as she continues competing in speedcubing events.
