During the first year of Song Zhezong Shaosheng (1094), Su Shi was demoted to Yingzhou (now Yingde, Guangdong). On the way to his post, he was told to be demoted. Two days later, he was told to demote him to Huizhou, and he was demoted three times in ten days. About three years before birth (1096), Su Dongpo learned that Guangzhou people drank alkaline water, so he suggested using "tap water". He proposed "making a big stone trough under the rock, introducing five big bamboos, and then coating them with hemp." Race anywhere and go straight to the city. "Guangzhou magistrate Wang Zhong attached great importance to Su Shi's opinions and put them into practice.

Churchill: Sacrificing a City for Secrecy

1940165438+10/4, Coventry, an important British industrial city, was bombed by the Germans. However, to the surprise of the Germans, Churchill knew about the German air raid plan before the bombing began, but he finally decided not to take any defensive and transfer measures.

1936, the German Intelligence Agency activated a password compiled by the machine. This cipher machine is durable and easy to operate, maintain and carry, so it is named "mystery". Hitler believed in mystery very much. In order to understand the "mystery", the British tried their best. After hard research, the British finally had a "jigsaw puzzle" and named it "bomb"

At the end of 1939, the "bomb" deciphered the German cipher communication. Since then, various secret plans and action plans of the German army have been sent to Churchill's desk. In fact, most of the German actions during World War II failed to hide from the British, but the British hid their intelligence sources well. It was not until the repeated defeats in the British air combat that Hitler began to doubt whether the riddle was safe, so he ordered the German army to carry out air raid tests. 1940165438+1October 12, the German Air Force stationed in western Europe was ordered to dispatch 500 planes and drop 4500 incendiary bombs on Coventry within 48 hours. The British "bomb" quickly deciphered the information. However, for the sake of secrecy, Churchill finally decided not to prepare for air defense. As a result, Coventry, a prosperous city with a population of 250,000, became a "dead city" during the German bombing of 10 hours.

However, for Britain, Coventry's sacrifice is of great value. With the help of the "bomb", the British got out of the initial predicament. After Britain won the air battle, it successively won the Atlantic naval battle and the North African counterattack. When the allied forces returned to the European continent from Normandy, Churchill said to menzies, director of the secret intelligence agency, on the dock in Cherbourg, France: "Remember, since Coventry, we have been fighting this world war with the pulse of the Germans!"

Soong Ching Ling: "I am a neat freak"

/kloc-in the autumn of 0/943, Soong Ching Ling donated a large sum of money to the anti-Japanese soldiers and civilians, and the demand was in short supply, so people sent one of her fur coats to the auction house for sale. Chiang Kai-shek knew that the publicity of this matter would damage the reputation of the People First Party, so he sent someone to send money, which was rejected by Soong Ching Ling. Later, Song Meiling personally sent a large sum of money. Soong Ching Ling blocked it with her hand and said with a pun, "Sister, you know I'm a neat freak. There are too many people taking this bill, which is too dirty. "
