Ping pongs originated in England at the end of the 19th century. It is said that there were two English tennis enthusiasts at that time. Once they had a tennis match outdoors. When it was hard to separate, it rained heavily, forcing the two energetic young people to hide in the school canteen. Then they put the dining room table together, separated by a few bricks, and hit it with tennis rackets. Onlookers found it interesting, followed suit and swept across Europe.

When playing ping pong, the eyes keep staring at the ball, follow the ball to a distance, back and forth, can effectively exercise the ciliary body movement and lens contraction, so that the eye muscle activity is large, eye blood supply is sufficient, vision is not easy to degenerate, is a good way to prevent visual decline.

A paddle is a rowing tool. The upper end is a round rod, which is easy to hold by hand. The lower end is a plate-shaped paddle, which is used to pull water. Newton’s third law in physics is used to make the ship move forward through the reaction force of water wave. So what does paddle tattoo mean? Is there any special meaning?

Agriculture is the development basis of people’s clothing, food, housing and transportation. Only when agriculture is guaranteed, people can better invest in industrial development. Even in today’s scientific and technological era, food is still the basic material guarantee for people’s life. If a country does not have enough food guarantee, people’s life will not have any guarantee. Although it can import food abroad, it will not be able to go abroad Food prices are not so low.

As the world’s largest power, the United States has not only a strong science and technology economy, but also a very developed agriculture. With the large mechanized farming method and the flat and fertile land, the agricultural production efficiency of the United States is high, and the unit planting cost is low. As early as the 1940s, mechanized production has been realized. In the 1960s, the mechanized utilization degree of grain is higher, and the whole process mechanization of staple grain has been realized. In the 1970s, the mechanization of planting beet and cotton has been realized, as early as 1987 At that time, the per capita output value of agriculture in the United States reached 55300 US dollars, ranking first in the world, and also becoming the largest exporter.

The reason why agriculture in the United States is so strong is that the farm mode is relatively developed. 50% of agricultural products are produced by 2% of large farms. Its operation modes include owner system, company system and partnership system. At present, there are 2 million farms in the country, and 86% of them are private farms. Of course, the personal quality of American farmers is relatively high. 20% of them have bachelor’s degree. Those farmers will write their farming experience and publish books to make money. It is these highly educated farmers who can play with high-tech machinery. Today I’m going to show you the farm tattoo. I hope it can inspire you.
