Up to now, it has been three years since the COVID-19 outbreak. In the past three years, the world economy has suffered heavy losses. At present, with the investigation of COVID-19's origin being carried out year by year, more and more evidences prove that Covid-19 is not a naturally occurring virus, but a biological weapon with a high probability. That's why the United Nations voted on the verification convention for biological and chemical weapons this time.

On the military side, we should devote ourselves to preventing biological attacks against combatants, and strengthen special cooperation with the social public health system to strengthen the ability of the whole society to deal with large-scale epidemics. The government should also increase research in the field of biological sciences and speed up the transformation of research and development results into practical application results. Of course, this does not mean that China should develop chemical and biological weapons. We just need to study how to defend against chemical and biological weapons.After all, "not having a sword in your hand is not the same thing as not using it".
