《管子·侈靡》
双方势均力敌则战，一方处于守势则攻。成百的房舍没有建筑，成千的村落没有神庙，这种情况就叫作 破败 。对这样的国家是可以一举而取的。
钧则战，守则攻，百盖无筑，千聚无社，谓之陋，一举而取。
When the two sides are equal in strength, then fight; when one side is on the defensive, then attack. Hundreds of houses are not built, thousands of villages have no temples, this situation is called ruin. Such a country can be taken in one fell swoop.
