In 1979, our People's Liberation Army was forced to launch a counterattack against Vietnam, which was also the most wonderful war launched after the founding of the People's Republic of China, our army was like a bamboo, it took only 28 days to capture more than 20 cities, reached the outskirts of the Vietnamese capital, gave them a harsh lesson, and then quickly withdrew from Vietnam. Today, decades have passed since the war against Vietnam, and Vietnam has never recovered from the war, because their economy, industry and other aspects are still relatively poor and backward. Why hasn't Vietnam been able to turn around yet? It was only because General Xu Shiyou issued 3 orders before withdrawing, many people at the time thought it was superfluous, and now they know how important it is.

Vietnam is a white-eyed wolf country, and when the United States invaded them, we provided them with a large amount of material and personnel support to help them drive out the US troops, thus achieving national reunification. However, at the instigation of the Soviet Union, they constantly harassed the people on our borders. Our country warned them, but they took it as a deaf ear and still went their own way, so the People's Liberation Army launched a counterattack war to protect the national territory and the people on the border from foreign aggression, hoping to teach them a lesson. Therefore, after the invasion of Lang Son, our army chose to withdraw, and just in case, General Xu Shiyou also issued three orders, and these three orders have still made Vietnam unable to turn over.
The first: lay mines along the way. In order to prevent the Vietnamese army from pursuing, so that war would break out again, affecting the speed of retreat, Xu Shiyou ordered the laying of mines. Because if our army does not successfully retreat within the stipulated time, the consequences will be very serious. First of all, the rainy season in Vietnam is coming, when the road is very muddy, which will seriously affect the speed and health of the soldiers' march, and secondly, the country needs to be vigorously built, and the PLA soldiers need to invest in national construction after winning the war, so there is no need to drag mud and water with them. Finally, the Soviet Union at that time also looked at our country and gathered a million troops to the south to prepare to attack our country. For these three reasons, our army needs a quick battle, so we planted mines to prevent the Vietnamese army from pursuing.
The second is the destruction of all strategic resources. After the outbreak of the Vietnam War, our army provided them with a large amount of strategic materials, and after the end of the war, these materials were not brought back, and some of them were used by them to harass the people on our border, and some of them were randomly piled together. In order not to let these substances continue to remain in the hands of this white-eyed wolf in Vietnam and let them continue to use them against our country, General Xu Shiyou ordered them to be destroyed. This effectively weakened the military strength of the Vietnamese army, although they also captured a large number of American weapons at that time, but those weapons were too advanced for them to be used, and our weapons were very suitable for them.
The third is to destroy Vietnam's important heavy industry. Industry is the most basic facility of a country's military and economic development, and when our army retreats, it is destroyed, resulting in a great impact on their economic development, and there is no way to recover in a period of time, combined with the destruction of their strategic materials, even if they want to continue to oppose our country, there is no time and economic support. Because the first thing they have to do is to restore their domestic industry and restore economic development, otherwise their country may face extinction.
Therefore, these three orders issued by General Xu Shiyou were to recruit and subdue the enemy, so that they simply did not have any extra energy to continue to wage war with our country. Until now, Vietnam's economy and industry have no way to recover, and they have to rely on other countries' financial support to survive. Because they thought that if they leaned on the big tree of the Soviet Union, they would be able to live a good life, so they offended our country, and what they did not expect was that the Soviet Union itself was too busy to take care of itself, and finally had to announce its disintegration. Therefore, vietnam's current state can only be said to be self-inflicted.
