ABSTRACT

Whenever an enemy comes from afar and their spirit is sharp, it is advantageous for them to quickly engage in battle. Accordingly, you should deepen your moats and increase the height of your fortifications, securely defending your position without making any response in order to await their enervation. Even if they irritate you with taunts and insults, trying to provoke combat, you still cannot move. A tactical principle from the Art of War states: "The secure can be tranquil."
