u"Sun Tzu's Art of War:

\u6545\u5175\u77e5\u5f7c\u77e5\u5df1,\u767e\u6230\u4e0d\u6b86,\u4e0d\u77e5\u5f7c\u800c\u77e5\u5df1,\u4e00\u52dd\u4e00\u8ca0;\u4e0d\u77e5\u5f7c\u4e0d\u77e5\u5df1,\u6bcf\u6230\u5fc5\u6b86.

If you know the enemy and know yourself, you need not fear the result of a hundred battles.
If you know yourself but not the enemy, for every victory gained you will also suffer a defeat.
If you know neither the enemy nor yourself, you will succumb in every battle."
