每当人们谈起中国古代著名战略的时候,常常引用的一个脍炙人口的例子就是隋末农民大起义中李密给杨玄感进的三策。当时正值隋炀帝发动了第二次征讨高丽之役,在后方督运粮草的重臣、前丞相杨素的儿子杨玄感乘隋炀帝大军在外徒劳无功、国内动荡不安民怨沸腾之机起兵反隋。作为杨玄感的谋士,李密给他出了三个战略:北据幽州,断炀帝后路,为上策;西入长安,为中策;就近攻东都洛阳,屯兵坚城下,为下策。 Whenever people talk about the famous ancient Chinese strategy, often quoted a popular example is the Sui Mi peasant uprising Lee Mi to Yang Sen three policies. At that time, Emperor Sui Dili launched the second consulate in Korea. In the rear, he was supervising the minister of grain and water. Yang Xuan, son of former prime minister Yang Su, flew futilely by the army in Sui Dynasty and the domestic turmoil began to rise. As Yang Xuan sense of counselors, Li Mi gave him out of three strategies: the North according to You state, off the emperor Road, the best policy; west into Changan, as the middle of the policy; near the east attack Luoyang, Tunbing strong city, as the best policy.
