The COVID-19 outbreak is a major public health emergency that has spread fast in the country, causing the most extensive infections since the founding of the People's Republic of China. The epidemic is also the most difficult to contain in the country so far. President Xi Jinping took command of China's war against COVID-19. "The Chinese nation has experienced many ordeals in its history, but it has never been overwhelmed. Instead, it has become more courageous and more mature, rising up from the hardships," Xi said.
