The world under the sword is a battle of ideas and entanglements of grudges and grudges.
The great road is invisible, the great sound is silent
To protect a place's peace and seek prosperity, what exactly is needed?
There is never less intrigue and filth in the world than in the court.
It's just that morality in the arena has always been more important than in the temple.
Hold the sword in your hand to keep the world safe; hold the sword in your heart to keep your moral principles intact.
Intention: Standing between heaven and earth, one should keep one's original intention
