Six-year-old speedcuber Lian Yunzhi set a new world standard in competitive Rubik’s Cube solving during September 2026, breaking the 4.5-second barrier twice in under 72 hours at official World Cube Association (WCA) tournaments in China.
Breaking the 4.5-Second Barrier in Wuhan and Guangzhou
Lian first captured the women’s world record at the WCA Wuhan Danqiu Cube Competition, held between September 12 and 14, 2026. Across five official timed attempts, she recorded an average time of 4.52 seconds to claim the global mark. Just days later, at the WCA Guangzhou 3x3x3 Speed Two-Round Competition IV, she eclipsed her own newly minted record by posting a 4.27-second average.

According to CCTV reports, those successive times make her the first and only female speedcuber to average under 4.5 seconds—a performance threshold previously attained almost exclusively by top male competitors in the global rankings.
A Rigorous Training Routine Behind the Records
Behind the rapid ascent lies a regimen modeled after high-performance athletics. Lin Yangxi, Lian’s mother, initially enrolled her daughter in Rubik’s Cube classes at age four simply as an extracurricular pursuit alongside dance and music. The puzzle quickly displayed an exceptional match for the child’s aptitudes.

Lian now practices between two and three hours daily in Chengdu, located in China’s Sichuan province. She has memorized more than 1,300 algorithms, dedicating at least 30 minutes every day to review them. Her training also emphasizes “look-ahead”—the cognitive ability to anticipate subsequent turns while her fingers execute ongoing physical movements.
Early Milestones and Neurological Development
The recent records follow an earlier breakthrough in June 2025 at the Southwest Universities Cube Open. At just five years old, Lian solved a 3x3x3 cube in 4.973 seconds, making her the youngest person in the world to drop below the five-second barrier in an official competition.
Her family rejects the notion of forced obsession, viewing the practice instead as an exercise in neurological development. Lin Yangxi noted in local media interviews that solving the puzzle involves far more than blind memorization. Regular practice builds spatial logic, strengthens concentration and memory, and trains children to handle competitive pressure, victory, and defeat alike. A crowded shelf of trophies in their Sichuan home marks the beginning of an ongoing competitive career.
