How do the shapes of ancient Chinese maps change compared with modern maps?

Map is very important to us. If a person has a bad sense of direction, he must hold a map. Otherwise, there is no place to be found at all. Nowadays, our maps are of the printed type. Once printed, a large number of maps can appear. The maps of the ancients are similar in shape to our current maps, but the maps of the ancients were all hand-drawn. After all, conditions were limited at that time.

We need to know that drawing a map is actually a very tedious task. Not only must all the mountains, rivers and features in the area be taken into consideration, but the accuracy of the drawing must also be ensured. The size must be grasped well. In the past, the economy was relatively backward, so it was necessary to be able to accurately ensure the accuracy of map drawing. In other words, if the ancients followed this map, it would be a good map as long as they did not go the wrong way when going out.

When the ancients drew a map, they first had to grasp three points: the first was the mountains and rivers, the second was the route, and the third was the proportion. The direction of the mountains and rivers needs to be implemented one by one by the painter, that is, walking out with feet. There was no positioning technology in ancient times. The ancients could only rely on their own feelings to understand the position. This way there would definitely be errors, and as the map range expanded, such errors would accumulate.

Secondly, the route is the benchmark. The route is of course a water transport route. Generally, the route is easier to draw and the probability of error is relatively small. The last thing is to grasp the proportion. In fact, the proportion is similar to the current scale. If it does not follow a certain proportion, then it may not be possible to draw a map on any paper no matter how large it is. Of course, the accuracy requirements of this method of proportion will be higher. Very high.

Looking at it, it is much easier for us to draw maps now, and we can use high technology to achieve it accurately. But the ancients couldn't do it. They had to measure it with their steps. The hard work of the ancients is worth learning from each of us.
