National security is the most important cornerstone of national development and the most fundamental guarantee for people's well-being. From the old adage that "benefits outweigh governance and harm outweighs chaos", to the deep wars and sufferings in some countries and regions today, and to the great harm caused by terrorism, we all know that nothing can be done without a secure foundation and a stable environment.

National security begins with the first step. This is not only a matter of the state, but also the responsibility of a certain government department. It is closely related to each of us. Every citizen of China has an obligation to safeguard our national security. On the issue of safety, we must plan ahead, be vigilant first, and establish a high sense of safety.

Strengthen the study of national security law, anti-terrorism law, anti-espionage law and other laws and regulations. Say no to all illegal acts that endanger national security with the bottom line drawn by law. Be prepared for danger in times of peace. Under the background of epidemic prevention and control, we should pay more attention to public health safety and biological safety. Ensuring national security and long-term stability requires the unremitting efforts of every citizen.

Now, in China, which has gone through the most difficult period of the war against COVID-19, we have countless angels in white, who carry the burden for us with the courage of their souls. Don't they have fear? Presumably, no one is fearless under the threat of virus or the worry of family members.

Academician Zhong Nanshan, who is 80 years old, still stands with us and has become our strong backing in the face of the China epidemic, just as we did with SARS more than a decade ago. They are not only the people who have dedicated themselves to us silently, but also the unknown staff from all walks of life in Qian Qian. They bravely face their fears: they enrich the mountains and seas with dust and fog, and illuminate the sun and the moon with the light of fireflies and candles.
