Wen - Xiao Xi
To say that one of the relatively large wars that occurred in our modern history was the self-defense counterattack war against Vietnam at that time, this war was not provoked by China first, but initiated by Vietnam, when Vietnam stabilized from the chaos of the war, and after breaking away from the control of France, we China also gave Vietnam a lot of help. But then Vietnam's approach made us very cold, Vietnam had the Soviet Union behind it, and then it began to harass our borders and mutilate our ordinary people. After much persuasion was fruitless, we directly dispatched 200,000 officers and men to attack Vietnam, and in less than a month we beat Vietnam to the ground, and this is not the end, we blew up all the factories and equipment that we originally built for Vietnam with explosives, and what should be taken away was also taken away, and nothing was left for this ungrateful Vietnam, leaving behind a piece of ruins, this matter is no wonder we China, to blame vietnam for underestimating us.

After the Sino-Vietnamese War, there is another country mixed in, this country is Mongolia, the predecessor of Mongolia is the Yuan Dynasty, when mentioning the Yuan Dynasty, many people will think of a person, that is, Genghis Khan, a generation of proud Genghis Khan, this is still Chairman Mao to Genghis Khan! We in China did not have any disputes with Mongolia before, and this was all caused by the Soviet Union's trickery in it, and the Soviet Union deliberately instigated it, because at that time, our Sino-Soviet relations were not very good, and even Vietnam was a pawn in the hands of the Soviet Union.
During our attack on Vietnam, the Mongols had been stirring up trouble in the northern parts of our country, so that our army had to disperse its forces to suppress and prevent the Mongols from starting a war, so that we would be attacked by the enemy before and after, and this situation was very unfavorable to us. When China and Vietnam were at war, Mongolia was the first country to stand up for Vietnam, and this country was actually a clown in front of us, and we didn't pay attention to him at all.
Such provocations lasted for a long time, knowing that after the end of the Sino-Vietnamese war, Mongolia was honest, in fact, Mongolia is still very smart, because this time we are the victorious side, they must have seen China's strength, if they still use their might, Mongolia may become the next Vietnam. Until now, the relationship between China and Mongolia has not been very good, but in any case, our great China is getting stronger and stronger, has gained a firm foothold in the international community, and the country has recognized our country, and I am proud of it.
