Hua Tuo was a great physician and pharmacologist at the end of the Eastern Han Dynasty in China, and made great contributions to enriching the ancient medical treasure house of China. Hua Tuo is not only proficient in medical skills, but also attaches great importance to the health care function of physical exercise.

Once, while studying in the study, Hua Tuo saw a child swinging the latch back and forth. He immediately thought of the old book "A family is not slow, running water is not rotten." Why don't people exercise every day like this and let the blood flow? Later, referring to "Introduction" (a method of overall physical exercise), Warren sorted out a set of boxing methods for physical exercise, which was called "Five Birds Play".

This kind of exercise is a gymnastics that imitates the movements of five animals, such as tigers, deer, bears, apes and birds, and can stretch the joints, back, waist and limbs of the whole body.

Hua Tuo's disciple, Wu Pu, has been doing "Five Birds Show" for decades and has lived to be over 90 years old. He still has light steps, bright ears and strong teeth. From this, we can see that "Wuqinxi" is an effective fitness gymnastics.

2. Inspired by children.

1608, Hans Liporsay, an unknown optician in middelburg, the Netherlands, built the world's first telescope. How was it invented?

One day, two children were playing some scenes in front of the shop in Libosai. They looked at the weather vane in the distant church through the front and rear lenses. Suddenly, they seemed to find something and were in high spirits. Lippert ran quickly, and he also picked up two lenses, and the weather vane in the distance was magnified a lot.

Liporsay happily ran back to the store and put two lenses on a spool. The world's first telescope was successfully trial-produced. Later Galileo imitated and made a telescope 32 times larger, which directly led to Heliocentrism's great discovery.

3. The discoverer of Lilliput

Levinhawk (1632 ~ 1723) was the inventor of the microscope. The invention of the microscope really started the observation and research of microorganisms. Levin Hook is just a janitor in Delway, the Netherlands. He used the janitor to grind a lot of lenses. Once, he saw things through two lenses and found that he could magnify tiny things many times.

Now, this has aroused his great interest. He used this lens to watch his Tatars and found many grotesque "lilliputian" residents. He was surprised to write: "There are more residents and small creatures living in tartar in one population than in the whole kingdom of the Netherlands!" " An old janitor invented the microscope and became the originator of microbiology.

Some people envy him and ask him the "secret" of success. Levin Hook said nothing, but held out his hands to the questioner, a pair of hands full of calluses and cracks due to long-term polishing of lenses.

4. Revelation from overturning the spinning wheel

James Hargreaves, the inventor of Jenny's textile machine, is an ordinary worker. He can both weave and be a carpenter. My wife Jenny is a kind and diligent textile expert. She is greedy from morning till night, but she never turns much. Every time Hager Rivaz sees his wife nervous and tired, he always wants to improve this old spinning wheel.

One day, he accidentally knocked over the spinning wheel at home. He saw that the hammer that had been placed horizontally had become vertical and kept turning. The accident inspired him: since the spindle can still rotate when it is upright, can't several yarns be spun at the same time if several upright spindles are used side by side?

He set out to make a new eight-spindle loom and named it "Jenny loom". This invention is dozens of times more efficient than the old textile machine and is regarded by Engels as "the first invention to fundamentally change the situation of British workers".

5. High heels

/kloc-a venetian businessman in the 0/5th century often went out to do business, but he was worried that his wife would go out to have an affair. One rainy day, he was walking in the street, with a lot of mud on his heels, and he walked very hard. Businessmen are inspired by this, because Venice is a water city and boats are the main means of transportation. The businessman thinks that his wife will not be able to walk on the springboard in high heels, so she can be trapped at home.

Unexpectedly, his wife felt very novel when she put on these shoes. Accompanied by the servant, she got on and off the boat and played around. High-heeled shoes made her more graceful, and fashionable ladies rushed to follow suit, so high-heeled shoes quickly became popular.
