To commemorate the 70th anniversary of the victory of the War to Resist U.S. Aggression and Aid Korea, the "Volunteer Army" trilogy will present the founding war of New China in a panoramic, multi-dimensional and three-dimensional manner. The movie "Volunteer Army: Heroic Soldiers Attack" is the first in the series. In the early days of the founding of the People's Republic of China in 1949, New China faced a situation of "internal and external troubles". Since the outbreak of the Korean War, the U.S. military has repeatedly provoked on the Sino-North Korean border, and civilians have been bombed. In order to maintain the hard-won peace and for the long-term stability of generations, in October 1950, the Chinese People's Volunteer Army entered North Korea, and the "War to Resist U.S. Aggression and Aid Korea" kicked off. This is a "national war" - in the Korean battlefield, even though the armament strength was very different, our army exchanged heroic sacrifices for successive victories; on the diplomatic stage, the delegation of the People's Republic of China appeared at the United Nations for the first time, and China's new voice won international respect. New China, not giving up an inch of land to promote national prestige; new youth, high-spirited to protect their country.
