《宋书·本纪·卷六》
下诏说： 古人说治理国家，军队应摆在首位，即使过了一百年没用军队，也不能忘记这一点，否则国家就危险。
诏曰： 昔人称人道何先，于兵为首，虽淹纪勿用，忘之必危。
The imperial edict said: The ancients said that in governing a country, the military should be put first. Even if the military has not been used for a hundred years, this point cannot be forgotten, otherwise the country will be in danger.
