In 1979, the People's Daily published a review article "It is tolerable or unbearable", which officially opened the prelude to the counterattack against Vietnam. In the previous decades, the Chinese people desperately helped this "comrade in the south" worth 14 billion U.S. dollars worth of supplies, and weapons and equipment alone could equip Vietnam's 2 million troops. However, Vietnam, with the support of the Soviet Union, persecuted the overseas Chinese and occupied China’s land after the Americans were beaten away. Faced with the perfidious Vietnam, the Chinese People’s Liberation Army, whose equipment has been reduced to “one-third of the grenade”, still sent troops. Two weeks have taught the white-eyed wolf Vietnam a lesson, but after the war, the unwilling Vietnam began to harass the Chinese border.
In 1979, the Chinese People's Liberation Army captured Lang Son, the northern gateway of the Red River Plain, and threatened Hanoi, the capital of Vietnam. At this time, the Vietnamese People's Army who invaded Cambodia also returned to Hanoi one after another, preparing to fight the Chinese army. The People's Liberation Army, which has reached a combat plan, will accept it as soon as it is good. What's more, the People's Liberation Army has been hit hard in previous battles. The originally planned two-week war was also prolonged for two days, so the People's Liberation Army quickly withdrew from Vietnam and returned to the country to rest.
After the People's Liberation Army withdrew from Vietnam, the Vietnamese government believed that the Chinese army had been "destructively attacked" by the Vietnamese army and was already vulnerable. It then sent troops to continue occupying Chinese territory and attacking Chinese border residents. In the face of repeated provocations by the Vietnamese army, the Chinese troops stationed at the Sino-Vietnamese border continuously launched counterattacks and annihilated more than 1,800 Vietnamese troops. Under the continuous attack of the Vietnamese army, the Chinese border guards could not support it either. In 1984, the Central Military Commission successively mobilized a total of 10 elite groups from the seven military regions to station at the Sino-Vietnamese border, and launched a counterattack against Vietnam.
Beginning in 1984, various army groups have continued to destroy the border strongholds controlled by Vietnam. For a time, people in Vietnam were worried and worried about the massive invasion of the People's Liberation Army all the time. They had to maintain a 1 million standing army on the Sino-Vietnamese border.
The Chinese army has rotated the troops of the seven military regions during the 10-year round of battle. The PLA has improved its combat effectiveness in successive battles and selected a new batch of PLA elites, such as the commander of the Northwest Military Region in "I Am a Special Forces" Lei Keming emerged in the war against Vietnam. Vietnam has also dragged down its economic construction because it maintains more than 1 million troops all the year round, and finally had to improve its relations with China and actively seek peace with China.
