We have protected people's lives and health to the greatest extent, and made significant positive achievements in coordinating epidemic prevention and control and economic and social development. The impact of the epidemic on the country's overall economic and social development has been minimized. "People first and life first" embodies the people-centered value pursuit of the CPC. Only when people's health is guaranteed can the country be strong and prosperous.
