When we meet on a narrow road, the brave prevails

The famous saying "We will see the difference in twenty years" is used to encourage oneself and despise the opponent.

It is convenient for oneself.

Always remember not to leave a way out for your opponent

It is never too late for a hero to take revenge

One more friend is equal to one more enemy.

Know yourself and the enemy, and fight a hundred battles without slacking off.

People who have no opponents are lonely.
