In 2017, with the successful conclusion of the "Ten Measures for Air Quality", the overall air quality in China improved, and key areas showed significant improvement. So, blue sky is no longer a "scarce commodity", and blue sky photos frequently appear in social media. Masks and air purifiers are unsold, and the "blue sky happiness" is full.

Why is heavy pollution weather coming again? How long can the blue sky last? Regarding this, Huang Runqiu, a member of the National Committee of the Chinese People's Political Consultative Conference and Vice Minister of the Ministry of Environmental Protection of China, pointed out that air pollution control is not achieved overnight, and under various conditions, heavy pollution weather will make a comeback.

Huang Runqiu revealed that the key to the next step of atmospheric governance lies in the adjustment and optimization of industrial structure, energy structure, and transportation structure. At present, China is formulating a three-year action plan to win the blue sky defense battle by 2020, and a series of rectification measures are constantly being reported.

Environmental protection work also relies on public participation. When everyone works together to practice green development and green lifestyle, blue skies and white clouds can always exist.

Yansheng Instrument has launched an air quality monitoring micro station, which focuses on the basic monitoring parameters of our meteorological environment and comprehensive monitoring of "two dust and four air", allowing us to have targeted management.
