Maintain social distance is we want to convey the main concepts, we will be the number two meters into the concept of death's Long knife. The man on the left of the bus stop is infected with a virus. Death finds him, the person targeted by Death is a dead person, and his long sword can indirect damage trying to close to. So want to ensure the safety of their own, be sure to guarantee two meters distance between people, don't take the initiative to close to every one of us. 保持社交距离是我们想要传达的主要概念，我们将两米这个数字融入到死神的长刀这个概念当中。公交站牌左边的人感染了病毒，死神找到了他，而被死神盯上的人意味着死亡，他的长刀也可以间接性的伤害试图靠近的人。所以想要保证自己的安全，务必要保证人与人之间的两米距离，不主动接近每一个人。
