In ancient times, the so-called heroic men must have the integrity to surpass others, and they cannot tolerate human feelings. When a common man sees humiliation, he draws his sword and stands up to fight. This is not brave enough. There are great brave men in the world who are not surprised when faced with a sudden attack, and are not angry when someone is attacked for no reason. The person he holds hostage is very big, and his ambition is very far-reaching. ------- Su Shi's "Lun on Liuhou"
