If our expectation of advantage be tempered in this way, we may succeed in accomplishing the essential part of our schemes.

Lionel Giles's notes

信, according to Tu Mu, is equivalent to 申, and 務可信也 is paraphrased by Chang Yü as 可以伸己之事. Tu Mu goes on to say: “If we wish to wrest an advantage from the enemy, we must not fix our minds on that alone, but allow for the possibility of the enemy also doing some harm to us, and let this enter as a factor into our calculations.”
