A clear blue sky one day in Seoul
The sky in Seoul will be clear in 2020 due to the spread of the Corona 19 virus.
Especially, fine dust did not come over from China, so there were many clear days in the sky was clear.
Before the summer, there were many uncomfortable days due to fine dust, but this year, I wear a mask due to the Corona 19 virus even though there was no fine dust.
It’s not easy to see in Seoul, so I filmed it.
