Since we are born as a human we should explore self field, vast, far and deep, and should be tender but impossible to be rolled up; be rigid but impossible to be kinked; be kindhearted but impossible to be invaded; be trustable but impossible to be insulted; be brave but impossible to be duped; be too wise to lose any chance to defeat. Nothing would be out of your strategy, because you map out the plan in your command tent, but win the victory thousand mile away and because you pre-perceiving let nothing fled.
