Faced with this kind of cross-border behavior of the Vietnamese army several times, the country finally couldn't bear it, and decided to send troops to take military action on Faka Mountain and restore our country's control of Faka Mountain, known as the Battle of Faka Mountain in history.

The Battle of Faka Mountain was another large-scale battle after my country's self-defense counterattack against Vietnam, which ended in the victory of the Chinese army. After the victory of this battle, the question of the ownership of Faka Mountain has become the focus of dispute between the two countries.
In 1999, China and Vietnam signed a border agreement, which divided more than 1,000 square kilometers of land including Faka Mountain, but it is still unknown how the Faka Mountain is divided.
According to our country’s non-disclosure agreement at the time, the ownership of the Wakayama area has always been highly classified. So now, decades later, where does Faka Mountain belong?

At six o'clock in the morning on May 5, 1981, the Battle of Faka Mountain officially started. The battle lasted 57 days. Although the number of participants on both sides was relatively small, the battle experienced multiple forms of integrated battles such as defending strongholds, fighting counterattacks, and artillery.
The Vietnamese army has successively invested various forces, artillery, tanks, mortars, etc., and poured more than 20,000 shells into our army’s Fakashan station. After the war, the entire land of Faka Mountain was lifted by one layer.
In order to regain Faka Mountain and smash the conspiracy of the Vietnamese authorities, the 9th Regiment of the 3rd Division of the Border Defense Army stationed in Mingxian, Guangxi and the 123rd Division of the 41st Army were secretly transferred to the vicinity of Faka Mountain.

At that time, the entire Waka Mountain was buried by the Vietnamese authorities. Luo Guozhou, the commander of the fourth company of the second battalion of the 9th Regiment of the Guangxi Military Region, took the lead. He rushed to the front and fired the blasting tube. It took only nine minutes with the whole class. Time cleared the mine barrier of nearly a thousand square meters, paving the way for the offensive troops.
Afterwards, our soldiers quickly assembled their forces and attacked Faka Mountain, killing 9 enemy troops and wounding 14 enemy troops. The troops quickly turned into a defensive state. Subsequently, the Vietnamese authorities carried out three crazy counterattacks on the Wakayama area and fired two thousand shells on the narrow Wakayama area. The four companies in the battle center in the depths faced the battle calmly, giving priority to logistics, dealing with the enemy, and successfully repelling the enemy's three counterattacks.
At night, the Vietnamese army once again formed a small number of troops in an attempt to attack our army at night. The Vietnamese army first attacked our army's positions 3, 4, and 5. The People's Liberation Army of our country has paid the painful price of 59 deaths, successfully wiped out 257 enemies and smashed the enemy's offensive.

In the early morning of May 19th, 1981, the Vietnamese authorities were unsuccessful and attacked the Faka Mountain area with a battalion under the cover of the artillery. The Chinese People’s Liberation Army resisted desperately, killing more than 100 enemies and repelling the enemy’s counterattack. .
The Vietnamese authorities, who are still unable to attack the city under the cover of shells, are furious and have threatened to find another breakthrough to retaliate against our army, trying to eliminate the Chinese army in order to save face. But at this time, the Vietnamese army was already seriously injured, and the offensive plan was put on hold.
After the large-scale conflict in Faka Mountain on May 5, 1981, to the four years when the Chinese People's Liberation Army was engaged in the recovery war in Laoshan in 1984, the Faka Mountain area was relatively safe. In order to cooperate with the Yunnan front, the Vietnamese army basically assembled in the Laoshan area. The victory of the Battle of Faka Mountain greatly shocked the Vietnamese authorities.

Between May and June of 1981, my country had five large-scale military conflicts with Vietnam. In the Battle of Faka Mountain, the most tragic battle for our country was the 9th Regiment of the Third Division of the Guangxi Military Region's border defense army against the attack of the Vietnamese army. A total of 78 soldiers were killed and 154 were injured.
In the battle for more than a month, our army wiped out 705 enemy troops, wounded 513 enemy troops, and destroyed the enemy’s artillery, tanks, cars, seized rifle ammunition, and a batch of military materials.
Although our army won an absolute advantage in the Battle of Wakayama, the ownership of the region around Wakayama has become a legacy issue of the battle.

Faka Mountain has always been a very important strategic junction on the Sino-Vietnamese border. More than 20 kilometers to the south is Langshan, an important border defense town. The mountains run north-south and there are roads built between them. If our army can control Faka Mountain, it can control the traffic fortress in the north, and the defense against the Vietnamese army in this generation is like a thorn in the back, making the enemy frightened.
On the other hand, if the Vietnamese army controls Wakayama, it will be able to eliminate Lang Son’s adverse impact on its border defense, and further push forward the investigation station, threatening the traffic and regional security of dozens of square kilometers of my country’s Guangxi border. Whose territory is Faka Mountain?
In 1999, my country and Vietnam conducted a total of 16 rounds of negotiations. The "China-Vietnam Land Boundary Treaty" was signed around Faka Mountain, which divided the disputed 1,000 square kilometers of land on the border between China and Vietnam. However, what about the boundary of Faka Mountain? Distribution, but the official did not specify.

So, rumors about the ownership of the Faka Mountain Territory spread all over the Internet. In fact, the reason why the ownership of the Faka Mountain Territory is not announced to the outside world is also the request of our military. One is that there are still some territories in Faka Mountain that have not been surveyed, and the other is that our army has left military facilities on the main peak of Faka Mountain.
On December 31, 2008, the survey of the Sino-Vietnamese border was finally completed. After the two sides discussed, my country returned the positions 4 and 5 in the southern part of Faka Mountain. Our country retains positions 1 and 2.
As for the position of No. 3, the main peak of Faka Mountain, it is still occupied by our country. So far, after 18 years of negotiations, China and Vietnam have completed the assignment and assignment of the territory of the Faka Mountain.

Summary:
The Battle of Wakayama was a relatively large-scale local battle after the founding of the People's Republic of China. The behavior of the Vietnamese authorities has undoubtedly caused serious harm to the people of both countries. Although our country has won the battle, the issue of ownership of the Faka Mountain region has become a problem for our authorities.
's actions to return the Faka Mountain 4 and 5 positions to Vietnam caused dissatisfaction among some people. This is actually understandable, the Faka Mountain position was obtained by our heroic spirits regardless of life and death. However, in today's rapidly changing times, the Faka Mountain Territory is undoubtedly a sword hanging in the relationship between China and Vietnam. A little carelessness may be used by other countries and cause disputes again.
In order to put an end to this behavior, the Chinese authorities took the initiative to return positions 4 and 5 to Vietnam, which embodies our country’s beautiful aspirations for peace and also urges the Vietnamese authorities to prevent such tragedies from happening again.
