600 words about the weather and one thing about me.

I go to work by bike every day. Due to the difficulty in breathing in weather phenomena such as smog, haze, light fog, sandstorm, sand blowing, floating dust and smog, the effective horizontal visibility is less than 10KM due to the influence of a large number of extremely fine dust particles or smoke particles floating in the air. Sometimes it is difficult for meteorological professionals to tell the difference. It is necessary to comprehensively analyze and judge the weather background, sky conditions, air humidity, color and smell, satellite monitoring and other factors to draw a correct conclusion. The weather phenomena of fog and haze can sometimes be converted to each other. Smog is harmful to the human body after being inhaled into the human respiratory tract, and it can be fatal in serious cases.

Outdoor sports should be reduced in this weather. It is best to wear protective measures such as masks. JD.COM Mountain has disposable masks imported from the United States, such as Puweixin and Green Shield. Safety and hygiene, avoid infection.
