(30) A city of three miles, a country of seven miles, attacked from all sides and was invincible. If you attack it around, you will have the right time. However, if you don't win, the weather is not as good as the right place.
Surround the inner city of three miles and attack it from the outer city of seven miles. There will be fighters when the weather is right, but if you can't win, it's better to be in the right place.
(3 1) The city is not high, the pond is not deep, the army is not strong and profitable, and there is not much rice. It is not as good as people and peace.
The city walls are not low, the moat is not deep, the weapons and armor are not sharp, and there is not much food. Abandoning the city and fleeing is that the favorable terrain is not as good as uniting the people.
(32) As the saying goes, the people in the territory do not take the edge of the frontier, the country does not take the risk of mountains and rivers, and the benefits of the world do not take the benefits of military revolution. Those who gain the Tao help more, while those who lose the Tao help less. When there is little help, relatives will be there; Help more, and the world will be at peace. Take advantage of the world and attack your relatives. A gentleman wins without fighting.
Therefore, border sealing can't control people, Jiangshan can't save the country, and sharp weapons can't become the world. People with morality get more help, while people without morality get less help. When there are few people to help, even relatives will betray; When the number of people who help is extremely high, people all over the world will obey. Fight against those who will betray their loved ones with the power of obedience from all over the world, so there is no doubt that they will win without fighting.
