The emperor ordered a court painter to create a painting titled “The God of War Yuan Daoji Marches to Battle.”
One day, when His Majesty visited the painter's courtyard to inspect the work, he was stunned to find a horde of monsters besieging a city in the painting.
The emperor flew into a rage:
“What the hell?! What is this?”
The painter replied:
“Your Majesty, this is ‘The God of War Yuan Daoji Marches to Battle.’”
“Who are all these people?! And why are there monsters?!”
“Your Majesty, this is the frontier, where a horde of monsters is besieging a city.”
The emperor roared, “I asked where my trusted general Yuan Daoji is!”
“Your Majesty, General Yuan is making a getaway.”
Facing the oncoming enemy, Yuan Daoji thought to himself:

And so he ran.
