Korean have been suffering from yellow dust especially in winter and spring from China. Most of yellow dust begins from Mongolia but it’s getting serious because a lot of pollutants mixed through some factories in China. We didn’t have that problem before 10years. 10 years ago It has been a national problems since Chinese have been industrialized. But China never admit it and do nothing improve for this problems.does nothing. Therefore, the problem has increased. That’s why so many Korean hates to Chinese. Last year we experienced a very clean air even though in spring because of Corona China stop to factory.because some Chinese factories were shutdown to the pandemic. I watched news that people in India can see Himalayas from their villages for the first time in 20 years. And d Dolphins came back to ocean in many countries. Maybe Corona gave nature to heal time time to heal and punishment to humans. When I was in Korea before, I was very sensitive about air quality so I had checked it up everyday. There are many app that let us know the air quality every hour and every day. If the fine dust concentration level more than 50, I wearied wore masks and try not doing out side. stay outdoors for a long time. If more than 100, Education office sent a officer document that let teachers do not allow students go outside and do not open the window. But when I was in China, most of days were ,it was more than 150. Less than If it it is less 150, everyone would open the window to ventilate whole house. When a fine dust is too harsh, I couldn’t see the front of me. there's zero visibility. Sometimes I felt that I will be die with fine dust. The problem of air pollution is that the symptoms appears after so many years. So many Chinese never sense serious of air pollution. Humans are animal of adoption. I gradually became dull from fine dust.
