Editor's Note: Ever since the novel coronavirus pneumonia exploded into a full-blown COVID-19(named by WHO) epidemic in late January, governments at the national, provincial and local levels in China have worked tirelessly to not only contain the pathogen's spread and save lives but minimize the outbreak's impact on various economic sectors. Extraordinary policy decisions, supportive measures and financial help were extended in quick time to rescue or protect vulnerable sectors like micro, small and medium enterprises.
