In practical application, it can be divided into two categories and four levels. "Cutting" and "cutting" belong to the "no war" thinking; "Cutting soldiers" and "attacking the city" belong to the thinking of "cautious war". First, "going to the army to cut the plot" refers to a comprehensive operation that relies on strategic use, including political, economic, cultural and diplomatic means, and solves disputes in advance without waiting for the intensification of contradictions between the opposing sides. Second, the "second cut-off" refers to mobilizing the strength of the country and relevant countries to show their determination, producing overwhelming advantages or balance of power, supplemented by knowing the benefits, and achieving strategic goals through setbacks and compromises without resorting to force. Third, "two reductions" refers to the use of some military forces to solve the enemy outside the enemy's political and economic center of gravity, thus reducing the war losses to a minimum. Fourth, "attacking the city from below" refers to the last resort when the above three efforts fail, that is, seizing the enemy's strategic location and even all the territory. It must be admitted that in military confrontation, even if one side is in an advantageous and active position, it is not easy to achieve the goal of wiping out the enemy without fighting.
