The first: The invention of ice cream

Ice cream, the earliest ice cold drink originated in China. In the late Tang Dynasty, people used a large amount of saltpeter when producing gunpowder. It was discovered that when saltpeter dissolves in water, it absorbs a large amount of heat and can cool the water to the point of freezing. Therefore, Chinese people could also make ice in the summer. At that time, adding ice cubes to lotus seed and mung bean soup or mint and lily soup was a very popular drink. By the Yuan Dynasty, smart businessmen added fruit pulp and milk to the ice for sale, which was very similar to modern ice cream.

1533 Marco Polo brought this ice cream recipe back to Italy, and Europeans had the opportunity to taste ice cream. In 1560, the personal chef of Queen Catherine of France invented semi-solid ice cream with milk, frozen fruits, fresh egg yolks, and fat as the main ingredients and engraved patterns on it to make the ice cream more colorful and delicious. It gradually developed into what we have today. Edible ice cream.

The third one: Leaning Tower of Pisa

The Leaning Tower of Pisa was completed in 1350, but the construction started earlier than 1174. Back then, when the project progressed to the third floor, people discovered that the tower was tilting due to reasons such as the foundation and building structure. So the project was interrupted. Later, work resumed.

The tilt of the Pisa Tower continues to increase, reaching 4.5 meters now, and the tilt continues to increase at a rate of 1 millimeter per year.

The fourth: Zhao Siwan eats human liver

Zhao Siwan in the Fifth Dynasty loved to eat human liver. He tied the living person to a wooden post, cut open the stomach, cut off the liver, fried it and ate it, and then ate the liver. The man with the liver is still screaming. Zhao Siwan ate a total of sixty-six servings of human livers from his rebellion to his defeat.

Fifth: Cao Chuan Borrowing Arrows There is Someone Else

The real protagonist of "cao Chuan Borrowing Arrows" in history is not Zhuge Liang , but someone else. Sun Quan had a passive "wooden boat receiving arrows" in the water battle with Cao Cao .

One day, Sun Quan took a large ship and broke into Cao's army camp from Ruxukou to observe the military situation. Cao Cao ordered all bows and crossbows to fire at the Wu ship. Sun Quan's ship was tilted to the point of capsizing due to too many arrows hitting one side. Sun Quan immediately ordered the ship to turn around and let the other side receive another arrow. After the arrows on both sides were balanced, they returned safely

From this we can see that Sun Quan's "borrowing arrows" was not planned in advance, but an accidental incident. The arrow was shot directly on the plank of the ship. Therefore, it should be a passive "wooden boat receiving arrows", and there is no "scarecrow" in "thatched boat borrowing arrows".
