But which river does Hedong Hexi refer to? Hedong and Hexi, two uncertain pronouns of regional names, where are they now?
Common sayings and rivers
Thirty years in Hedong, thirty years in Hexi, strictly speaking, should be regarded as a complex idiom. This idiom was first seen in Wu's Scholars. The original text is: Mr. Da, thirty years east, thirty years west.
Among them, Hedong Hexi refers to the Yellow River, the mother river of our Chinese nation. Wu used this sentence to talk about the Yellow River for two main reasons.
One is to divert the Yellow River, which is a metaphor for the fate of the world or people. It's always changing. Wealth comes and goes, there is no fixed number.
The second is to use this sentence to ridicule life, even with a hint of inexplicable hope. Maybe one day, by chance, everyone can become a powerful person?
It's just that most historians think that Wu, who was deeply hurt by feudal society and imperial examination system, didn't really think so, just talked about comforting him.
On the surface, it is full of hope for life, but in fact it has a strong color of feudal superstition. After all, no one can say for sure that things like "the tables have turned", so we have to hope for "the darkness".
Just like the diversion of the Yellow River, how do human resources determine the change of the Yellow River course? Don't say that the Qing dynasty couldn't do it. Even in modern society, it is also a great hero that attracts worldwide attention.
Fortunately, people's thinking has never stopped and has always been positive and optimistic. When the wheel of history rolled forward, the ancients gained another understanding from this proverb:
History is constantly advancing, and we can't look at everything with a static eye. Everything is dialectical, and we can't look at everything from the perspective of stories.
The Yellow River channel is used to describe the vagaries of life and satisfy countless people's beautiful imagination of the future.
What future generations should know is that although the Yellow River is known as the mother river of the Chinese nation. But every time the river is changed, it will bring great harm to the people.
This also indicates that the future life of each of us may not be as easy as people think.
Teenagers looked straight at them and said indignantly, thirty years in the east and thirty years in the west, we should let them know that a bright future is not to let nature take its course, but to do our best.
After all, changing life is never a simple project.
Hexi Hedong
As for Hedong and Hexi mentioned in the complex sentence idioms, we can find the answer from the historical documents of various dynasties of the Chinese nation.
Taking Hedong as an example, the earliest known word "Hedong" was recorded in Oracle Bone Inscriptions of Shang Dynasty. After some textual research, archaeologists decided that Hedong, recognized by the ancients at that time, should be the south of Shanxi.
The original answer has been confirmed, but the cultural development and changes in the late Shang Dynasty and the early Zhou Dynasty, as well as the different evaluations of Hedong in later generations, have to be overthrown and started again.
In the Qin Dynasty, the scope of Hedong County was defined for the first time. Until the Han dynasty, this title has not changed. Therefore, Hedong has two different explanations.
On the one hand, it is a vague and broad concept area, on the other hand, it refers to a certain area in a specific way. In the Tang Dynasty, Hedong was finally defined.
After the establishment of Hedong Road in Tang Dynasty, Hedong Road was changed to Hedong Road in Song Dynasty on the basis of Tang Dynasty.
Although the Ming Dynasty abolished this administrative division rule under the influence of the provincial system in the Yuan Dynasty, the area referred to by Hedong was basically fixed, which is now the southwest of Shanxi Province.
Southwest Shanxi, isn't this Northeast Shaanxi?
This problem is also explained in Er Ya. Hexi Zhou. Anyone who knows the history of the Three Kingdoms and the division of counties in the Eastern Han Dynasty knows that Yongzhou, as a big northern state, is really large.
Even in this large area, Hedong seems to be included. Is there a conflict?
In fact, the answer is not like this. The ancients opposed Hedong Hexi because of the name, which was expressed by geographical description, and was not the optimal solution to this problem.
First, it is recorded in the Biography of Qin Shihuang that Lao Ai takes Taiyuan County in Hexi as his country, and the river here is mainly Fenhe, the second largest tributary of the Yellow River.
Secondly, because of the Huns in the Han Dynasty, the rivers in Hexi, especially the Yellow River from Gansu to Qinghai.
Under different understandings, the specific location of Hexi will naturally change. Of course, if the area opposite the "Hedong" is turned into Hexi for convenience, there is actually not much problem, depending on personal understanding.
