Entering April, as the temperature gets higher day by day, the most "nightmare" flying season of the year has arrived......
Recently, when I was walking on the road, large and small "hairs" were flying all over the sky, and it was fine to get on my clothes and hair, but the bad thing was that they would also get into my nose and make you unable to breathe.

How did the annoying flying flotsam come about, and is there any way to reduce its impact on life? If you are also curious about these questions, let's read on together~
