“Their blows are correlated. The cheng and the ch’i are compared to two interlocked rings: ‘Who can tell where one begins and the other ends?’ Their possible permutations are infinite; the cheng effort may be transformed into a ch’i, a ch’i into a cheng. Thus we may redefine a ch’i attack as one made where a decision is speedily attainable at least cost, in an area characterized by voids or fissures in the enemy’s defences.”
