Lian Yunzhi, a six-year-old from Chengdu, China, broke the women's Rubik's Cube average record twice in three days with times of 4.52 and 4.27 seconds at WCA competitions. She is the first female to post an average under 4.5 seconds, trains two to three hours daily, and has memorized over 1,300 algorithms. While she now holds the women's record, overall single and average records remain faster.

A six-year-old girl from Chengdu, China, has stunned the speedcubing world by breaking the women's Rubik's Cube world record twice within three days. Lian Yunzhi posted average times of 4.52 and 4.27 seconds in 3x3 competitions at two World Cube Association (WCA) events, establishing herself as the only female competitor to record an average below 4.5 seconds.
Record-Breaking Runs
Yunzhi set her times at the WCA Wuhan Danqiu Cube Competition and the WCA Guangzhou Three-Speed Double-Wheel Competition IV, according to local broadcaster CCTV. Video of one run shows the young cuber—nicknamed "Zhizhi"—wearing a red gingham bow as she rapidly manipulates the cube and celebrates when she realizes it is solved, reports ITV.

Training And Technique
Lian began cubing after being enrolled in a class alongside other activities such as dance and music. Her mother, Lin Yangxi, told local outlets that she encouraged the hobby after recognizing cubing as "an excellent activity for fostering a child's comprehensive abilities." Lin says Lian has learned more than 1,300 solving algorithms and practices two to three hours each day.
"Solving a Rubik's Cube improves focus, memory, logical thinking, spatial awareness, and helps develop a healthy mindset toward winning and losing," Lin said. "It's not just about blindly memorising formulas, but using logical reasoning to find optimal solutions."
How Her Times Compare
Although Yunzhi now holds the women's average record, she remains behind the overall world records. Per Guinness World Records, the fastest single solve is 2.76 seconds by Teodor Zajder (Feb. 8, 2026), the first sub-3-second single, while the fastest average of five solves is 3.51 seconds by Yiheng Wang (June 17, 2026).
Yunzhi's achievements highlight a remarkable level of skill and composure for her age and point to a promising future in competitive cubing if she continues to train and compete.
