"The Roar of the Tiger and the Roar of the Dragon" Zhuge Liang repeatedly raised troops to invade the north of Wei, but all returned without success. It was a waste of national power and a waste of money and people. Why did Zhuge Liang do this against nature?

Ten years

I raised troops five times

Exhausting Yizhou’s financial resources

Many bones of those who died in battle

A woman who misses her family in the fields

Who could have expected that things would go against her wishes

However, the Han Dynasty will be at peace

If Chang'an is not recovered

Sooner or later, it will be annexed by the Wei State. In fact, Zhuge Liang should have known that his life would not be too long. If he did not regain Chang'an, the Shu Kingdom would surely perish quickly after his death. Therefore, he must regain Chang'an during his lifetime, even if I know clearly that this body is going against heaven.
