Maps bring great convenience to people. In the final analysis, most students used paper maps, and more people used mobile navigation to look at mobile phone maps. We might as well trace back to when the earliest map in history appeared. The following leaderboard 123 brings the earliest recorded map details of China.

The earliest map in the history of China: the map of Gong Yu area.

1700 years ago, Pei Xiu, a native of the Western Jin Dynasty, completed 18 Regional Map of Gong Yu, which is the earliest historical atlas in China and the earliest recorded historical atlas in the world. In the preface, he put forward six principles of surveying and mapping, namely the famous "six bodies of surveying and mapping", which laid a theoretical foundation for the traditional map of China (the map drawn by plane survey), so Pei Xiu was called the founder of traditional cartography in China.

Needham called him "the father of scientific cartography in China", and Ptolemy Claudius (about 90- 168), a famous cartographer in ancient Europe. He is two brilliant stars in the history of ancient cartography in the world.

"Drawing six bodies" is: the daily minute ratio (scale) used to measure the size of the area; The second is aiming (direction), which is used to determine the orientation of things everywhere; Three roads (distances) are used to determine the route of the road; Four-day competition (high take-off, take-off is a horizontal straight line distance); Five hazards (take the oblique approach and take the oblique as the straight line distance); Sixth, it is circuitous straight (circuitous straight, straight is a straight line distance). To sum up, these six principles are Pei Xiu's brief introduction to the three elements of scale, direction and distance discussed in modern cartography, indicating that it is necessary to make a scale, measure the direction between objects and obtain the horizontal straight-line distance between objects.

Pei Xiu also pointed out the functions and relationships of the six bodies. He believes that the six bodies must be comprehensively used and referenced with each other, otherwise a map reflecting the actual terrain cannot be drawn correctly. These mapping principles put forward by Pei Xiu are the basic scientific theories for drawing plane maps, which laid a scientific foundation for drawing maps. They have always influenced the traditional cartography in China before the Qing Dynasty.

The oldest map of the New World in the world.

Maps are something we used to see, because there are maps of the world and China hanging in the classrooms of junior high schools or senior high schools. Although mobile phone maps are very popular now, there are still some commemorative maps that have attracted people's attention ... click to view them.
