The back of heroes can give us strength and security, while each other's songs can give us warmth and love. Therefore, we believe that judging whether it is the hero's back or the other's song is determined by the different values embodied in specific behaviors. For example, Academician Zhong Nanshan resolutely took the train to Wuhan in order to fight the epidemic in his later years.
Let us feel that during the epidemic, Zhong Lao gave us a sense of security, which is the hero's back. Zhong Lao asked us to wear masks in front of the camera to cheer for everyone and let us feel each other's warmth. This is the other party's song, so the hero is ours. The hero's back and the other party's song can make the hero do different forms of behavior.

20021114 to February 17 China experts and 17 foreign experts formed a joint expert group, which was divided into three working groups: epidemiology, molecular traceability and animals and environment. On this basis, a 28-day global traceability study in China was conducted in Wuhan.
According to the existing scientific evidence and investigation results, the joint expert group conducted a qualitative risk assessment on the possibility of four modes of human-to-human transmission in COVID-19, and made an assessment at five levels: extremely unlikely, impossible, possible, relatively possible and very likely. According to this report, it is "more likely" that COVID-19 came directly from the original animal host.
It is "very likely" to be introduced into humans through intermediate hosts, "very likely" to be spread through cold chain foods, and "very unlikely" to be spread through laboratory events.
