Before the founding of New China, it was in the midst of perennial wars, coupled with the late start of China's industrialization development, which made many countries still have a backward and weak impression of China. However, a war to resist US aggression and aid Korea quickly sobered up many countries. After the War to Resist US Aggression and Aid Korea, China entered a stage of recuperation and rapid development.
But because China has always advocated peaceful solutions to problems, and China was isolated internationally at the time, many countries have revived the idea of taking advantage of China. For example, at that time, Vietnam not only began to alienate China for various reasons, but finally directly aimed its cold guns at Chinese border officers and soldiers and border residents.
Self-defense counterattack against Vietnam
The mainland had hoped that they would sit at the negotiating table as calmly as their own, but Vietnam ignored the mainland's requests and continued to attack China. The mainland had no choice but to launch a counterattack against Vietnam, but do you know what Vietnam did during this period that caused Xu Shiyou to be furious and even said that he wanted to "leave no room in Lang Shan"?
General Xu Shiyou
Vietnam is overconfident
Although Vietnam confidently drew up its battle plan before the war officially began, and acted like it didn't take much time to beat China to the ground. Unfortunately, the country was overconfident, and when the war officially began, Vietnam realized that it was not an opponent at all. In just a dozen days, the Chinese People's Liberation Army hit the Langshan area.
Stick to Lang Shan
If the Chinese army successfully breaks through the Lang Son blockade, then Hanoi, the capital of Vietnam, will be in an extremely dangerous situation. Therefore, the Vietnamese side demanded that the soldiers stick to Lang Son. By March 1979, the elite 308th Division of the Vietnamese Capital Defense Force had arrived from Hanoi to reinforce Lang Son. This unit had received great help from Zhou Xihan, commander of the 13th Army of the People's Liberation Army.
It can be said that the Vietnamese 308th Division can become one of the country's elite troops, thanks to the mainland's previous help. However, it was such a unit that, after receiving the order to hold lang shan, began to shoot our army by all means. Most importantly, after seeing that it could not inflict the expected effective casualties on our army and could not hold the mountain, this force also used large-scale chemical weapons against our army.
Shelling Lang Shan
This behavior made General Xu Shiyou, who commanded the battle, furious, and he angrily issued orders to the troops that no house on the mountain could be left after the established dawn attack began. In the ensuing battle, the Chinese artillery showed great power and inflicted heavy casualties on the Vietnamese defenders stationed at Lang Shan.
Finally, we may wish to add that according to the comparison data between the actual area of Lang Shan and the number of shells fired by our army at that time, when our artillery shelled Lang Shan, the number of shell landing points was 3 / square meter. You can imagine how miserable the Vietnamese army was at that time.
