After the war, Vietnam did not want to recuperate, but plundered neighboring countries to quickly restore its strength. Soon, they turned their attention to China and began to harass our borders, causing a lot of trouble to the local people. 1979, China decided to launch a self-defense counterattack against Viet Nam.
Many people in Vietnam have been brainwashed by the Vietnamese government and are very hostile to the PLA. They even pretended to need help, cheated the PLA's trust, and then shot people in the back. Although it took us less than a month to reach the Vietnamese capital, many people may not understand the difficulties during this period.
