This movie and its prequel, both are for the purpose to inspire the Chinese patriotism for the 1.4 billion subjects under the tight control of the CCP regime. The Chinese Communist Party has found their reign over its people has dwindled by several foreign influences:1) The internet. All the lies, all the rewritten historical facts by them are exposed on the internet. They are losing control over their once obedient slave-like citizens. The internet has bad influence that endangered the stability of its once tamed subjects who begin to open their eyes and can think by themselves more freely.
2) The overlooked impact to allow their once brainwashed people to travel abroad. The open-gate policy allowing the Chinese people witnessed the democratic systems, the freedom of speech, freedom to think logically.
3) The influences by joined the WTO. Trading with the free world, not just with goods, but also thoughts.
There are more reasons to alarm the CCP to take emergent measures to retract and refrain its subjects back to the iron cage to be re-brainwashed and re-educated with their lies. How? The easiest and most effective method is through media propaganda, i.e., the movie industry.
Thus came with the new wave of patriotic movie productions one after another. To make their people re-ignite their blind, blood-boiled patriotism and the hatred to all the democratic countries, especially the United States and Japan. "The Battle at Lake ChangJin (2021)" and its sequel, "Water Gate Bridge (2022) movies were churned out with several other supporting ones, such as "Snipers (2021)", "My Country, My Parents (2021)", "My People, My Homeland (2020)", "The Sacrifice (2020)", "The Eight Hundred (2020)", "Hi, Mom (2021)" and so on. All of these movies are produced with one goal: To rekindle the dying and waning patriotism and loyalty to CCP and stabilize the infrastructure of Communist China. All of the above listed movies were enjoy fantastic success in box office. Record tickets selling were kept breaking, simply in China. Patriotism is always a good sale in China and only in China. High 5 to CCP, you did it and did it again, and again. Long live the CCP, long live the Communism in Chinese Style!
