Not as terrible as it was at the beginning, this is the only time in my memory that a virus has spread so severely. I was quarantined at home and not allowed to go out. It limits my freedom, makes me feel bored, and it deprives many people of their lives. This mode of transmission is also very rapid, spreading to the world. All we can do is obey the government. It is best to stay at home, do not go out and wear a mask for protection. I calculated the time. It has been almost two years since the virus outbreak just started, which is very long and terrifying.
