Sometimes I feel like Jinyong and most Wuxia fans are kind of braindead stupid, like they know how important footwork is, or 轻功, but they believe shit like Zuo Botong's Ambidexterity Technique works by just having your arms do different things; "draw a circle with one hand and a square with the other", then you can use multiple techniques at the same time. But this doesn't take footwork into consideration at all..
