The smallness of human beings makes us realize that the epidemic has brought too much pain to the world, which we cannot recover either materially or spiritually, and we cannot forget this memory.

The use of masks to maintain order seems to be the most direct method for the spread of the epidemic. In the face of natural disasters brought by the nature of the epidemic, masks in the outbreak of the epidemic, the performance of the role is very little, and this measure, can not truly alleviate our trauma. As hard as we try, the old normal world won't come back. The innocent suffering caused by the epidemic is irreversible.
