There are actually four countries in history. What are their differences and where do they come from?

These four countries are Polygonum orientale, Polygonum occidentale, Polygonum orientale and Polygonum orientale. Among them, Xiguo is closer to Haojing, Dongguo is closer to Luoyi, Beiguo is closer to Xiayang City near Luoyi, and Nanguo is closer to Sanmenxia. So these are the four most famous vassal states in history. However, although they are inextricably linked, their background is different. Of course, the first ones were Xiguo and Dongguo. Later, due to the war, Nanguo and Beiguo were developed on the basis of these two countries. That's why four countries have emerged.

At that time, the two countries, Dongguo and Xiguo, were the most powerful. And once became the most powerful vassal state in the Western Zhou Dynasty. However, Dong Guo was later destroyed by the State of Zheng. This vassal state played an important role in many subsequent expeditions. This is because the military strength of this vassal state is very strong, and it is also highly valued by the whole Western Zhou Dynasty. So at that time, the strength of the vassal state was greatly strengthened. And once rose to the strategic level.

at that time, there was also a very chaotic situation in China. At that time, there was a great contradiction and conflict between Xiguo and Zhou Pingwang. It will lead to the final elimination of Xiguo by Qin people. Then the remaining people of Xiguo moved their fiefs to Xiayang City near Luoyi. And thus established the North Polygonum. Therefore, this is also the origin of Beiguo, but Beiguo did not have a strong military force because of the constraints of the State of Jin. So in the end, it also led to the demise of Beiguo.

Of course, another branch moved to the vicinity of Sanmenxia, and later Nan Guo was established. However, this vassal state has more powerful military power. And once returned to the previous strength. Then later, because the state of Jin was very powerful, it also led to the demise of Nan Guo. Since then, these four vassal States have also disappeared from the historical stage.
