In practical application, it can be divided into two categories and four levels. "Cutting" and "cutting" belong to "no war" thinking; "Cutting soldiers" and "attacking the city" belong to the thinking of "cautious warfare". First, "attacking soldiers and plotting" means relying on the comprehensive operation of political, economic, cultural and diplomatic means to resolve disputes in advance before the contradiction between opposing sides intensifies. Second, "second-hand-off" means mobilizing the strength of the country and the countries concerned, showing determination, causing overwhelming superiority or To achieve strategic goals without resorting to force. Third, "second-hand attack" refers to using part of military forces to solve the enemy outside the political and economic center of gravity, so as to minimize the war damage. Fourth, "attacking the city below" refers to the last resort, that is, capturing the enemy's strategic sites and even all the territory, when the above three efforts are ineffective. It must be acknowledged that in military confrontation, people are completely defeated without fighting.
