A, Dayu water conservancy

Once upon a time, there was a man named Dayu, who was the most famous hero in ancient China. His father's surname is gun, so Dayu is still a descendant of the Yellow Emperor. Legend has it that during the reign of Emperor Yao, floods often occurred in the Yellow River basin. In order to prevent floods and protect agricultural production, the emperor once called a meeting of tribal leaders to solicit water conservancy experts to quell flood disasters. Gun is recommended to be in charge of this work. He simply surrounded the residential area with dams to prevent floods, but failed in the year of hatred.

After Shun Di succeeded to the throne, Yu, the son of Gun, was appointed to take charge of water conservancy. Dayu summarized his father's experience in water conservancy and adopted the method of "leading the lag downstream". Forward relief uses the natural trend of water flowing from high to low to dredge the crowded stream, introduce the flood into the dredged rivers, depressions or lakes, and then connect the four seas, thus calming the flood. Later, Yu became the first king of the Xia Dynasty, and was called "Shen Yu", which was passed down from generation to generation.

Second, cross the rubicon

In order to solve the siege of the giant deer, Xiang Yu led his troops across the Yellow River to save Zhao. After the whole army crossed the Yellow River, Xiang Yu ordered all ships to be sunk, cooking pots to be broken, and his barracks to be burned, with only three days' dry food to show his death, and he had no intention of withdrawing troops. The army with no retreat finally defeated Qin Jun, and the bravery of Chu army greatly improved Xiang Yu's prestige.

Third, return to Zhao intact.

During the Warring States Period, King Hui of Zhao got a treasure from Chu named He Shibi. When Zhao Haoqi, the king of Qin, heard about this incident, he wrote to Zhao Huiwang that he was willing to exchange fifteen cities for Cui. When Zhao saw Lin Xiangru, Lin Xiangru expressed his willingness to go to Qin with Choi. If the prince of Zhao gets the city, he will give the Choi-hi to the king of Qin, otherwise, he will definitely bring the Choi-hi back intact.

After Lin Xiangru came to the state of Qin, he presented the jade to the king of Qin. King Qin Zhao was very happy, but he didn't mean to give the city to the prince of Zhao. Lin Xiangru said to the king of Qin, "This jade has a small flaw. Let me show it to the king. " He took Baoyu back and went to the pillar and said, "The prince of Zhao was worried that Qin would be strong on his own and refused to give Baoyu to the city. After my persuasion, he agreed, and Zhao Wang fasted for five days before I paid my respects to Qin.

The king, on the other hand, has simple manners and no sincerity to exchange. If the king must rob Baoyu, I'd rather hit my head on the post with Baoyu. Qin had no choice but to take out a map and draw fifteen cities for Zhao. Lin Xiangru was worried that the king of Qin was just pretending to deal with it, so he offered to fast for five days and set up a "nine guests" ceremony as a solemn exchange. The king of Qin had to agree. Lin Xiangru sent his entourage with Cui and returned to Zhao by the original road. When the exchange ceremony was held, Lin Xiangru told the king of Qin that Cui was sent back to Zhao, thus preserving Cui.

Fourth, refer to a deer as a horse.

During the Qin Ershi period, Prime Minister Zhao Gao monopolized the power. He wholeheartedly encouraged the accession to the throne, but he was worried that ministers would not listen to him. So they set a trap to test them. One day, in the court, Zhao Gao brought a deer and said to Qin Ershi, "This is a good horse, and I want to dedicate it to your majesty. Qin Ershi smiled and said, "The Prime Minister is wrong. This is obviously a deer. "

Zhao Gao shook his head and said, "Your Majesty, this is a horse. You can ask other ministers if you don't believe me. "

Ministers didn't understand what Zhao Gao really wanted at first, but when he turned to ask everyone if it was a deer or a horse, everyone understood Zhao Gao's sinister intentions. Although everyone knows that this is actually a deer, not everyone has the courage to stand up and tell the truth.
