"Hence, once we encounter these two forces, our first basic combat strategy is to do our best to let the Great Prince's faction engage in a tough battle, and before the Second Prince's faction attacks the city, we should weaken their long-range capabilities as much as possible, aiming at their weak points and avoiding their strengths."
"The second combat strategy is to remain unchanged in the face of change, with no need for proactive attacks. Just tighten up the horses and soldiers and be prepared to strike at any time."
"As for the third combat strategy, it is to do everything possible to provoke disputes between the two, weaken their military forces as much as possible, and gain an advantage."
