Rubik's Cube Solve Speed Guide: What Lian Yunzhi's Sub-4.5 Record Means for the Sport
Clocking a 4.27-second average requires absolute physical fluency across dozens of discrete mechanics. Competitive solving under World Cube Association rules grants each participant exactly 15 seconds to inspect the scrambled puzzle before touching it. Lian exploited this window with laser precision. During her inspection time strategy, she routinely mapped out not just the initial cross, but the complete orientation and insertion path of the first two corner-edge pairs.
Watch footage of elite solves and you will notice zero pauses between steps. Lian operated at a consistent turn rate exceeding 11.4 turns per second. Her execution relies on high-efficiency finger tricks, flicking cube faces with the sides of index knuckles and ring fingers rather than gripping full layers with whole hands. Her hands are visibly smaller than those of adult competitors, which forced her coaching team to customize the core springs, magnetic strength, and corner-cutting angles of her 54mm flagship cube to eliminate wrist fatigue.
