According to historical records, 1274, 10/0 on October 20th, the "Wenyong War" between the Yuan Dynasty and Japan had reached a white-hot stage. The Yuan Army landed in Hakata Bay, Japan in two ways, and the Japanese army was defeated. The Yuan army took the opportunity to pursue, but because the deputy commander Liu Fuheng was injured by an arrow in the pursuit, the offensive weakened, and it was getting late, so the Yuan army stopped attacking. That evening, the Yuan Army held a military meeting. Most generals think that the situation is unfavorable, many people overestimate the number of Japanese troops, and domestic reinforcements are not sent, advocating retreat. So Xindu ordered the retreat, but unfortunately, on the night of the retreat, a typhoon suddenly struck, and the mighty Yuan army was completely swallowed up by the strong wind ... In this expedition, the Yuan army lost more than 6,543,800 people, most of whom were not killed, but died in this storm. As a result, the Yuan Dynasty always dared not rashly attack Japan. The Japanese believe that this typhoon was saved by heaven, so they worship it and call it "kamikaze". This is the origin of the name "Kamikaze Commando" in the army during World War II.
