The Art of War (孫子兵法), Energy 埶篇

兵之所加如以碬投卵者虛實是也

That the impact of your army may be like a grindstone dashed against an egg — this is effected by the science of weak points and strong.

Lionel Giles's notes

虛實, literally “the hollow and the solid,” is the title of chap. VI. 碫 tuan is the T‘u Shu reading, 碬 hsia that of the standard text. It appears from K‘ang Hsi that there has been much confusion between the two characters, and indeed, it is probable that one of them has really crept into the language as a mistake for the other.
