If I were Zhuge Liang-

If you are Zhuge Liang with superior wisdom and noble character, what will you do in the following situations?

1. Although I know that Liu Bei can't accomplish the great cause of revitalizing the Han Dynasty, he still invited me out to help many times. What should I do?

2. Cao Cao's soldiers were besieged. Only Sun He joined forces to repel the stubborn enemy, but Sun Quan had different opinions on whether to fight or surrender. How can I convince them?

Liu Bei, Guan Yu and Zhang Fei are sworn brothers. They sometimes endanger the military because of brotherhood. How can I balance this relationship?

4. After the death of one master, the talents of the two masters were limited, and the national strength of Shu was weak, and Wei was eyeing it. How should I plan to complete the unified plan?

Although Ma Su lost his street pavilion, all the soldiers interceded for him, and the army was really short of generals. Should I deal with him according to military law?
