Claim who invented it and which dynasty

Legend has it that Fan Li, a native of Yue during the Spring and Autumn Period.

Legend has it that Fan Li found in business that people buy and sell things in the market, and they use their eyes to estimate the pile, and it is difficult to achieve fair trade, so he came up with the idea of creating a tool to determine the weight of goods. One day, on the way home from business, Fan Li happened to see a farmer drawing water from a well, and the method was very ingenious: erect a high wooden stake by the well, and then tie a horizontal log to the top of the stake; One end of the horizontal wood hangs the barrel, and the other end is tied with a stone, which is light and labor-saving.

Fan Lidun was inspired, and hurried home to imitate: he used a thin, straight wooden stick, drilled a small hole, tied hemp rope to the small hole, and used his hands to carry it; One end of the fine wood is tied to a hanging tray to hold the goods, and the other end is tied to a pebble as a stone; The farther the pebbles are moved from the rope, the more cargo can be lifted. So he thought:

How much cargo hangs on one end and how far the pebbles have to move to maintain balance must be carved into the fine wood. But what is the best thing to mark with? Fan Li thought hard for several months, but still couldn't get the point.

One night, Fan Li went out for a small relief, and as soon as he looked up and saw the stars in the sky, he had a whim and decided to use the six stars of the Southern Dipper and the seven stars of the Big Dipper as marks, one star represents one or two weights, and thirteen stars represent one catty. Since then, there has been a uniform measuring tool on the market - scales.

However, after a long time, Fan Li found that some businessmen with improper intentions were short of catties and two catties when selling things, and they deducted the people. He thought, how can the scales be improved to put an end to the evil deeds of the profiteers? Finally, he came up with the idea of changing the white woodcut black star to a mahogany inlaid metal star, and in addition to the six stars of the Southern Dipper and the seven stars of the Big Dipper, plus the three stars of Fu, Lu and Shou, with sixteen taels as a catty.

The purpose is to warn peers: as a businessman, you must be above board and not make black money. And said:

If a businessman deceives others, he will lose his blessings and happiness; If you deceive others, your descendants will never be able to get 'Yulu' (you can't be an official);If you deceive people, you will lose your 'yang longevity' (short life)! ”

In this way, the scale is a measuring tool that has been passed down from generation to generation and has been followed for more than 2,000 years until today.

It's a scale. It was invented by Fan Li.

Fan Li, the word young uncle, the year of birth and death is unknown, and he is from Chu in the Spring and Autumn Period. For more than 20 years, he worked hard with his literary colleague Yue Wang Jujian, died to destroy Wu, and was respected as a general. Li believes that it is difficult to live for a long time under the prince of Yue, and he knows that he can share hardships and hardships with him, and he is difficult to live with him.

To Tao, the art of manipulation to govern production, because of the huge wealth, self-named Tao Zhu Gong. Because there is a way to do business, and gradually become hugely rich, the people have respected Tao Zhu Gong as the god of wealth.

As follows:

1. Compass (Sinan), the earliest recorded Sinan originated from the Warring States Period, and its actual age should be insufficient to be examined. Its inventor is also difficult to find (it may be found in people's lives).

2. Gunpowder was invented in the Sui and Tang dynasties, originated from alchemy, and its inventor is also untestable.

3. Papermaking, Eastern Han Dynasty (102-105 AD), inventor: Cai Lun, place of invention: Luoyang.

4. Movable type printing, which began in the engraving printing of the Sui Dynasty, was developed and perfected by "Bi Sheng" during the Qingli period of Song Renzong (1041-1048 AD), resulting in movable type printing.

The historical influence of the four major inventions

1. The invention of papermaking has provided economical and convenient writing materials for human beings, and set off a revolution that is like a carrier of human writing.

2. The advent of printing accelerated the spread of culture and changed the situation that only the best people could read in Europe.

3. The application of the compass to navigation provided important conditions for European navigators to sail around the world and discover the New World of America.

4. The use of gunpowder Sen Li ** changed the way of warfare, helped the European bourgeoisie destroy the feudal fortress, and accelerated the historical process of Europe.
