My head, does my group story really exist?

True, even many characters are the original words of expeditionary veterans, but novels and movies are not based on real events, especially fictional characters like dragons do not exist. Take the Battle of the Worse Gate and the prototype Songshan as an example. The real battle ended in the sand table drill. A regiment guarded by the Japanese army was completely annihilated, a division of the expeditionary force was disabled, and bored brothers were buried there, so old Yu Xiaoqing didn't lie. He is the only one who is bored, and the battle of Bao Shu is actually more like an illusory dream. The truth is, the expeditionary forces and explosives were blown up one by one by geotechnical engineering. Bao Shu is so powerful that American planes can't effectively hurt it with a one-ton aerial bomb, let alone other shells of various calibers. If Chiang Kai-shek is not overjoyed, this battle can be won by siege warfare. The japs were hungry and exhausted in the end, and finally all the troops were wiped out.
