1, foreign military orders are not affected. The meaning of this sentence is that people who fight in other places will not have to follow the instructions of the heads far away from Beijing.

2, the original sentence is "the road is blocked, the city is not attacked, the land is not helped, and your life is not affected." When a general goes out to war, he can fight in an emergency, without asking for war in advance or waiting for the monarch's order to fight again.

The general is the executor of the monarch's mission. The situation on the battlefield is complex and changeable, so it is impossible for the monarch to get timely and effective battlefield situation information. Therefore, Sun Wu advocated that the general should lead the troops to war. According to the analysis of the specific situation, he could not listen to some orders of the monarch that did not meet the tactical requirements.
