Entering history and discovering history, many friends who like to study historical maps find a strange question, is the top of the map of the Yuan and Ming dynasties not complete, why is it a straight line?
In fact, the horizontal line represents the unknown world, leaving people to imagine, then in the end these two dynasties ruled the place north of the line?
One
The area north of the line was previously the area under the control of the Great Mongol State, while the north-south and wooded areas of the desert were ruled by Genghis Khan, and this area was also managed by some operations, and then reached the Mediterranean region and crossed the gulf and then established a superpower.
The eastern kings were the younger brothers of Genghis Khan, and another king was created during the period that belonged to him, the other of whom was Genghis Khan's own son, the western kings, most of whom ruled over the northeast region.
The kings of Xidao, on the other hand, ruled over some coastal grasslands, and after the changes of the times, they established the Khanate of Chincha, and Genghis Khan put his second son in charge of the old lands of Western Liao, which was historically known as the Chagatai Khanate.
His third son, then, put him in charge of the old land of Naiman, and later achieved success and established the Wokoutai Khanate.
As we all know, Genghis Khan also had a young son, his name was Tuolei, who gained the control of the northeast and eastern Xinjiang, but in the end it was directly controlled by the commander of the Yuan Dynasty.
According to previous historical maps, many of the Northern Islands and some plateaus were ruled by the Yuan Dynasty, and some territories were relatively stable after the destruction of the Southern Song Dynasty.
However, some of the areas on the map may not have even had towns at that time, where people were sparsely populated, and the climate environment was very harsh, and the terrain was not suitable for human survival and economic development.
Moreover, the horizontal line on the map also indicates a certain land size, and because of the spanning of some north-south territories, some places are easy to be ignored.
The neglected places are certainly not particularly important, they are not worth mentioning, and there have not been any major historical events in these areas. It was not until later "Russians" settled in the area that the history of the place changed.

History has recorded that at that time, there was a dynasty that had a relatively good relationship with the Yuan Dynasty, and there were many economic exchanges, but these places were not included on the map.
However, when the Dynasty changed to the Ming Dynasty, the rulers of the Ming Dynasty did not directly control Mobei, but instead took charge of the northeastern province of Liaoyang.
During the ming dynasty's rule, there were many administrative systems that borrowed from the Yuan dynasty's system, because there was a lack of original materials, and in some areas it could not be enough to prove that it really ruled the Arctic Ocean at that time.
In addition, during the Yuan Dynasty, because of some special reasons and circumstances, there were many survey points in the local area, so there were people guarding this point at that time, but the instruments and equipment were not so perfect at that time, so the outline of the northern region was not very certain at that time.
Now the horizontal lines on the map are shown, and those along the northern area are within these horizontal lines. With the passage of time, the Ming Dynasty also entered the late period, although with the change of time, many regional areas have changed, but those unknown areas are represented by horizontal lines, and they are not clearly divided, they are just some messy areas.

The horizontal line on the map of the Ming Dynasty is also different from the horizontal line on the map of the Yuan Dynasty, when the Ming Dynasty used a horizontal line instead of a latitude line, and at that time it was located in the northernmost area of that latitude line, and the Ming Dynasty did not have a clear right to control that area.
Moreover, the attributes of its latitudinal line were not really included in the area administered by the Ming Dynasty, and in the northernmost region at that time.
History records that there was a small tribe that had been holding the northernmost area of the Ming Dynasty at that time, but no one at that time knew some news about their tribe, only that they had been holding on to the northernmost region of the Ming Dynasty, and the people who later drew maps for the Ming Dynasty did not know how to draw it, so they only used a horizontal line to represent it.
Generally speaking, people who have seen the regional map of the Yuan Dynasty know that the map of the Yuan Dynasty will be marked with a special area, that is, Lingbei, because the weather in that area is not particularly good, the economic development is not so ideal, and even grain is a scarce material.
But because of the vast area, so its actual area is not specifically recorded, do not know how the human beings at that time were distributed in the region at that time, only know that the environment at that time was also very bad and difficult to survive, perhaps at that time someone directly used a horizontal line to represent it, but also left enough room for later people to imagine it, but also according to the approximate proportions to make a map of the drawing, drawing a simple straight line is not surprising.
