There are no eternal friends in the world, only eternal interests. This sentence is applied to Vietnam, and it is really the most appropriate. However, it does not matter to seek profits, what is important is that decades have passed since the bite back, and the result is still in the most primitive state. Therefore, what did the "interests" that Vietnam sought at the beginning bring to itself? When it comes to relations, the relationship between China and Vietnam is also quite complicated. All in all, for Vietnam, China is full of benevolence and righteousness, and it is not ashamed. As for China, Vietnam will never be able to get rid of the fact of "betrayal." As for why Vietnam has not turned over so far? Xu Shiyou's 3 orders when he withdrew, each of which hit the nail on the head!

As we all know, china has launched large-scale support to Vietnam just because of Vietnam's call for help. You know, at that time, China itself still didn't have enough to eat! As a result, he helped Vietnam. Don't ask Vietnam for anything in return, at least because of this, maintain a friendly attitude toward China and ensure certain cooperation in the future to achieve common development, right? But it turns out that the story of "The Farmer and the Snake" really exists in real life. In the face of the United States, Vietnam still did not hesitate to turn its back, choosing to aim its gun at China, and from time to time using the courage given by the United States to wantonly provoke on China's borders. What about the terrain advantage? As long as you touch the Bottom Line of China, you must know what is "pork on the board" in minutes!
In other words, after such a long period of development, Vietnam should be able to turn around smoothly with its own development. But why haven't you turned over yet? Many speculate that this may be related to Vietnam's own policies. However, many people also feel that this may be inextricably linked to the three orders before General Xu Shiyou withdrew. Speaking of which, Vietnam encountered General Xu Shiyou leading troops into battle, which was also unlucky. Who doesn't know that General Xu Shiyou has commanded the jute uprising, participated in the Liberation War, and is a well-known outspoken tiger general in the army! As for what those three commands are? First, lay mines along the way! General Xu Shiyou led his troops to retreat after attacking Vietnam, and in the process of retreating, General Xu Shiyou ordered everyone to plant mines on the road one after another. If nothing else, it is to prevent once an ambush is encountered in the front, there are mines in the rear, which can not let the team fall into the lineup of two-sided attack, and the battle of the trapped beasts is tantamount to waiting for death in situ, so it is enough to give such an order, which is enough to see the military talent of General Xu Shiyou.
Second, although the United States, after helping Vietnam, brought a lot of military weapons to Vietnam. But everyone knows very well that before accepting the help of the United States, China has always been providing assistance to Vietnam, so Vietnam itself has always used guns and ammunition from China. They were not familiar with the American weapons that had just arrived. Therefore, if all the weapons that originally belonged to China to support Vietnam are destroyed at this time, this will undoubtedly be a huge blow to Vietnam. Therefore, on the way to retreat, General Xu Shiyou ordered that all Chinese materials in Vietnam be destroyed, including guns and ammunition!
Third, General Hsu Shih-yệi ordered the destruction of heavy industry in Vietnam. In the early days, the Industrial Revolution was just emerging, so it is conceivable how important industrial development is for a country. No matter what kind of development a country has, industry has always been the most important premise and foundation for military and economic development. Therefore, when the Chinese army withdrew from Vietnam, it destroyed all of Vietnam's heavy industrial construction, which is enough to see how much impact it has had on Vietnam. In order to launch another offensive against other countries, Vietnam must take the lead in redeveloping domestic industrial construction and economic recovery, so in a short period of time, Vietnam will naturally become extremely honest.
These three orders of General Xu Shiyou can be said to have attacked seven inches of Vietnam, and it is believed that through this time, Vietnam also experienced the fate of offending China. Of course, it can also be seen that Vietnam, which thought that it could accelerate its development by holding the thighs of the United States, did not get its wish! Whether it was in the past, at present, or in the future, China has always adhered to the attitude of independence and peaceful coexistence. No one offends me, I do not offend. Rather than restricting other countries, China is still more willing to focus on its own development. After all, in this world, only if you are strong enough can you have absolute right to speak and a certain status!
