This is called ability to accomplish a thing by sheer cunning.
The _T‘u Shu_ has 是謂巧於成事, and yet another reading, mentioned
by Ts‘ao Kung, is 巧攻成事. Capt. Calthrop omits this sentence,
after having thus translated the two preceding: “Discover the
enemy’s intentions by conforming to his movements. When these are
discovered, then, with one stroke, the general may be killed, even
though he be one hundred leagues distant.”
