Six-year-old Chinese speedcuber Lian Yunzhi sets new women’s world records in 3x3 Rubik’s Cube speedsolving, breaking the women’s 3x3 average record twice within days. Multiple reports say she becomes the first female competitor to average under 4.5 seconds, with her results reported from World Cube Association (WCA) certified competitions.

According to outlet reports citing Chinese state broadcaster CCTV, Yunzhi first averages 4.52 seconds at a competition in Wuhan earlier in the month. She then improves to an average of 4.27 seconds at another WCA event in Guangzhou. ABC Australia and other sources describe her as achieving the record across these two separate meets.

Different outlets emphasize different aspects. Some focus on the milestone of averaging under 4.5 seconds and the “twice” nature of the record. Others highlight the specific average time of 4.27 seconds or present the story as a single world-record performance. Across coverage, the core details—age, event type (women’s 3x3 average), WCA certification, and the two average times—are consistent.
