1. History. "Biography of Huaiyin Hou", the letter is to make thousands of people go out first and carry water. ... this army is fighting to the death and cannot be defeated. Han Xin was born in Huaiyin (now southwest of Qingjiang River in Jiangsu Province). He is a general under Hanwang Liu Bang. In order to defeat Xiang Yu and seize the world, he made a plan for Liu Bang, first capturing Guanzhong, then crossing the Yellow River eastward, defeating and capturing Wei who betrayed Liu Bang and surrendered to Xiang Yu, and then eastward attacking Zhao Wangxie. Han Xin's troops will pass through a narrow mountain pass called Jingxingkou. Li Zuojun, the counselor of the Prince of Zhao, advocated sending troops to cut corners while blocking the mouth of Jingxing to cut off the supplies of the Han army. Without backup, Han Xin's expeditionary force will surely fail. But General Chen Yu refused to listen, relying on his military superiority, and insisted on fighting the Han army head-on. Han Xin was very happy when he learned that. He ordered the troops to camp 30 miles away from Jingxing, and in the middle of the night, let the soldiers have some snacks and let them eat after winning the battle. Later, he sent 2,000 Qingqi to sneak forward from the path and let them rush into Zhao's camp quickly after Zhao left the camp and hang the Han flag. Another 10,000 soldiers were sent to deliberately turn their backs on the river to lure Zhao. At dawn, Han Xin led the army to attack, and the two sides fought fiercely. Soon, the Han army defeated the backwater position for a pretence, and all Zhao troops left the camp and came to pursue. At this time, Han Xin ordered the main attack, and the soldiers who had no retreat turned around and pounced on the enemy. Zhao can't win and is going back to camp. Suddenly, the flag of the Han army was planted in the camp, and he fled everywhere. The Han army pursued the victory and won a total victory. When celebrating the victory, the generals asked Han Xin, "According to the art of war, this array can carry mountains on its back and face the water. Now you've asked us to line up in last stand, and you've said that you're going to give Zhao a full meal. We didn't believe it at the time, but we really won. What kind of strategy is this? " Han Xin smiled and said, "This is something in the art of war, but you didn't notice it. Didn't Sun Tzu's Art of War say,' You will be born when you are trapped, and then you will live'? If there is a retreat, the soldiers have fled, how can they be desperate! " This story evolved from the idiom "the last battle", which is mostly used in military actions and can also be used in actions with the nature of "decisive battle".

2.( 1) The story should have vivid plots and be attractive to students. Stories are more interesting than pale narratives, mainly because the story is vivid and can attract students' attention. If the teacher's class is interesting, his class will be successful.

(2) the story of cutting Chen in Lv Chunqiu:

Chu Zhuangwang wanted to crusade against Chen. He sent someone to find out the truth first. The spies reported: "The walls of the State of Chen were built very high, the trenches were dug deep, and the grain reserves were sufficient. The whole country looks very stable, so it is not suitable for crusade. "

Chu Zhuangwang's view is just the opposite: "Chen Guo is so small, but it can save so much food, which shows that the people are heavily taxed;" The high city walls and deep river ditches indicate the overuse of human resources. People must hate the monarch of such a country very much. As you can see, Chen Guo can completely crusade. So he sent troops to attack Chen, and it was easy to destroy Chen.
