Well, I also watched the news and expressed my views on the news content and the purpose of the Maine exercise in the United States: 1. First of all, the question you are worried about or concerned about: Are there really zombies? Is it similar to the movie and the game Resident Evil? This is actually very simple. The recent incident of eating noodle men, etc. , and the zombie virus in Resident Evil is very different. Basically, it is a drug that makes people insane and hallucinates, but people are alive, and their physiological functions and human strength have not changed suddenly. The bitten person is only bitten and will not be infected. I think infection should be the main means to spread the zombie virus in Resident Evil. 2. American culture is related and American culture is relatively open. On the one hand, this kind of exercise is to improve people's awareness of prevention and resilience, on the other hand, it is also a manifestation of humorous culture, similar to cosplay, and the local laws of various States in the United States are different, and many local regulations are quite interesting. Therefore, the purpose of this exercise is not only to train relevant personnel, but I think the entertainment content of cosplay is still quite high.
