Japanese typical spring weather Japanese typical spring weather (Journal March 27th, 2018) After I went back to home, I felt uncomfortable because I could not breath well. I had a blocked nose. Both PM 2.5 (particulate matter 2.5) and pollen covered my residential area thickly and I was suffered from them. Fortunately, I am not hey fever. I am nervous about PM 2.5. TV news had informed me that PM 2.5 which spread west part of Japan especially in spring was harmful for human's body. It has possibility to trigger respiratory system diseases and circulatory conditions. After a short time, yellow sand from China also float around my hometown. I wish they would disappear from the earth.
