Yellow Sand

　　Do you know a troublesome phenomenon, Yellow Sand, which is often seen in Spring in Japan and maybe South Korea. The fine particles flung up from the desert in the west of Peking streak from the west of Peking across the Korean Peninsula to Japan. It's nothing but an annoyance.
　　The yellow sand not only stains cars, but also damages their air intake system. My car is fortunately an electric car and doesn't need the air, but cars which are driven by gasoline would need more careful maintenance after the drive than usual. What's worse, it harms human health. My throat felt harsh now though I wore a mask all day. Nothing good comes from China.
