Laoshan, the name of the mountain, the local people of Yunnan are accustomed to call the largest and tallest mountain with lush plant growth in the vicinity as Laoshan.
Laoshan on the Internet generally refers to Laoshan in Tongta Village, Mengtong Township, Malipo County, which is located on the Chinese side between National Boundary Monument No. 12 and No. 13 of the second section of the Sino-Vietnamese border, and the northeast of Tianbao Port. The main peak is 1422 meters above sea level, with an area of about 8 square kilometers, and at the foot of the mountain is the national Tianbao port.
In 1979, your Vietnamese army took advantage of the retreat of our self-defense counter-attack combat units to occupy Lao Mountain, Bali River Dong Mountain, Kuolin Mountain, and Zheyin Mountain at all the riding line points on China's land border. In order to defend China's territorial integrity and protect the lives and property of soldiers and civilians in the border areas.
Here, in December 1983, the border troops of the Chinese People's Liberation Army began to accept combat missions to recover Laoshan and Zheyin Mountain (then known as "Two Mountains"). In the early morning of April 28, 1984, the vast number of officers and men of the Chinese People's Liberation Army swore an oath to "fight bloody battles on the top of the old mountain, return the territory in one day, defend the country as heroes, and stain the battle flag red with blood!"The battle oath was waged with flesh and blood against the Vietnamese army. With the unity and cooperation of all the soldiers and civilians participating in the war, after one tragic battle after another, by May 15, 1985, all the territory of the Laoshan area was recovered. Since then, Lao Son has become the main battlefield of self-defense and counterattack and defensive operations against Vietnam, and has also cultivated the "Lao Son Spirit" admired by the people.
