The spirit of the army is immortal. Next sentence

Heroes are immortal. By watching the patriotic film "800", students can recall the eventful years, relive the war years, feel the historical imprint, and start a prairie fire. It is these battlefields in blood shed that 800 heroes who did not regret their death and would rather die than surrender, together with many unsung heroes, built a spiritual monument. In the darkest hour of China, these heroes were born, and a single spark ignited the whole China.
