First, they sacrificed their rest time, and then they tested the tourists for nucleic acid. Because too many people participated, they sacrificed their rest time and tested overnight. In fact, for these retrograde medical workers, they are very selfless. Even at the expense of their rest time, they still have no complaints about it.
Another point is that they lost their lives, because there were so many people in contact during the test. Once a confirmed case appears, it is very dangerous for them. They are testing with their lives, because if they don't do this, it may cause widespread spread. The confirmed case belongs to walking virus. The last confirmed case, he was in Disney, so he said he was in Disney. They are all in danger of carrying the virus, but as medical workers, what they want is not to stay away from this place, but to test their retrograde and control the virus within a reasonable range.
In fact, these retrograde people are very selfless and great in our minds. It is because of their existence that we can feel at ease. Even though they have paid a lot in this process, I believe that as retrograde people, they have no regrets.
