Military technicians have a saying:
"I dare not be the aggressor, but rather the defender;
I dare not advance an inch, but would rather retreat a foot."
This is to move without moving,
To raise one's fists without showing them,
To lead the enemy on but against no adversary,
To wield a weapon but not clash with the enemy's.
No disaster is greater than taking the enemy lightly.
If I take the enemy lightly, I am on the verge of losing my treasures.
Hence, when opposing troops resist each other,
The one stung by grief will be the victor.
