The famous sayings in Sun Tzu's Art of War are as follows:

1. A soldier is more valuable than a soldier who will win a battle, but a soldier who is cheap will not last long. ——"Combat Chapter"

The most expensive thing to do with troops is to win quickly, and should not be delayed for a long time.

2. Attack the unprepared and take them by surprise. ——"The Beginning Plan"

Attack when the enemy is unprepared and take unexpected actions.

3. He who knows his enemy and himself can fight a hundred battles without danger. ——"Strategic Attack"

If you can thoroughly understand the situation of both the enemy and ourselves, there will be no danger in fighting any number of battles.

4. Chaos is born from governance, timidity is born from courage, and weakness is born from strength. ——"Military Strength"

Chaos and order, cowardice and courage, weakness and strength transform into each other under certain conditions. That is, if there is strict governance, there will be no chaos, and if the soldiers are brave, there will be no cowardice. A soldier who is strong will not be weak.

5. Those with power control power because of profit. ——"The First Plan"

The so-called situation is to make use of favorable circumstances to formulate adaptable strategies.

6. The affairs of generals should be kept quiet and rectified. ——"Nine Places"

When presiding over battles, one must be calm and unpredictable in considering strategies, and manage one's subordinates in a fair, strict and orderly manner.

7. All warriors must use the right combination to win by surprise. ——"Military Situation"

In general, when fighting with troops, we always use regular troops to fight the enemy and win with surprise troops.

8. Act if it is beneficial, and stop if it is not beneficial. ——"Nine Places"

We must be cautious in combat. Only when it is beneficial to the overall situation can we send troops. If it is not beneficial, we should stop immediately.

9. Those who are good at fighting can cause harm to others without harming them. ——"Virtual and Real Chapter"

Those who are good at directing operations can mobilize the enemy without being mobilized by the enemy.

10. More is more likely to win, less is less, but what about nothing?

——"The First Plan"

Those who plan carefully can win, but those who do not plan carefully cannot win, let alone those who do not plan well.

11. Throw yourself into death and then survive; fall into death and then live. ——"Nine Places"

When placed in a desperate situation, soldiers will fight desperately to survive.

12. If one does not fully understand the dangers of using troops, he cannot fully understand the advantages of using troops. ——"Combat Chapter"

If you cannot thoroughly understand the harm of using troops, you cannot truly understand the benefits of using troops. It means that only by knowing the advantages and disadvantages can we use our troops well.
