Feng Jun was removed from his post because he was not fully prepared to fight against the Nanjing epidemic, which further aggravated the situation of prevention and control of the COVID-19 epidemic in Nanjing, causing not only many deaths, but also a large-scale infection, so he was removed from his post. Judging from the seriousness of this matter, I think the country attaches great importance to the prevention and control of the epidemic in COVID-19, because the situation of COVID-19 epidemic abroad is still very grim, not only the number of infected people is very large every day, but also some countries are almost paralyzed in the prevention and control of the COVID-19 epidemic, which means that the whole country can't cope with the COVID-19 epidemic, but China itself has controlled the COVID-19 epidemic in a safe range, which is beyond the reach of other countries.

However, in the Nanking Lukou Airport infection, this kind of infection occurred because Feng Jun lacked attention and long-term understanding of the COVID-19 epidemic. The country should spend more energy and time to prevent and control the epidemic, which has caused irreparable losses. It should also pay for its own mistakes and give everyone an account.

From the outbreak of COVID-19 last year to this year, we have also seen changes. Many countries and regions have even been infected with the mutated COVID-19 virus. The mutated COVID-19 is not only more infectious, but also causes greater transmission pressure to more countries. We should also take daily precautions in our daily life, because only in this way can we better ensure that we are not infected. If we are accidentally infected with COVID-19 virus, we should immediately isolate ourselves and go to the hospital for treatment to ensure our lives and health.

Summary: In the face of COVID-19 epidemic prevention and control, we can't be careless, let alone relax our vigilance, but we must also take scientific precautions, and we must not blindly believe that it will not only be ineffective, but even produce a lot of useless work, leading to a waste of our time and energy.
