Since the birth of human civilization, many things have happened with human activities. We call the events and activities closely related to human society and the records of these things history.

History has always existed objectively. History is the inheritance of culture and can be expanded and extended, but most textbooks only record some important historical events.

Six interesting cold knowledge of world history is not in the textbook, and many people have heard of it for the first time.

1. Post stations in the Qing Dynasty were usually used by the imperial court to convey information, provide accommodation for officials and replace horses. After the Qing Dynasty, the setting of post stations was more standardized, with a total of 1785 post stations. On important official documents, it was also marked "immediate delivery".

The post station has corresponding regulations on the daily itinerary, generally 300 miles per day, with three grades of 400 miles, 500 miles and 600 miles. There are strict rules on the use of the post office. Only in a very urgent situation can you use the most advanced postal express, that is, 600-mile express, commonly known as "600-mile express" or "800-mile express", which is very urgent.

1268, the use of glasses was recorded in roger bacon, Europe, and Benjamin Franklin invented near-far glasses in 1784. However, as early as before the Song Dynasty, the prototype of glasses appeared in China. Let's test everyone here. Before glasses were known, why was it called cobra in China?

Third, deerskin is money. During the period of Emperor Wu of the Han Dynasty, due to the perennial conquest, the national finance could not keep up, so the court thought of a way to solve this problem.

Fourth, copying newspapers, there was a "treasure" in the early years of the Western Han Dynasty, but its function was to pass documents and copy newspapers and play the role of a transit station.

In the Song Dynasty, newspapers had many names and were strictly controlled by the imperial court. "Hailing Collection on Banning Tabloid" said: "Tabloid people are suspected of entering the theater ... because of their age. I don't know at home or abroad. Government officials must contend with small paper books and fly far away to be called tabloids ...
