As of April 13, willow catkins in central and southern North China, most of Huanghuai and other places have been flying. Shanxi, Hebei and Northeast China will also gradually enter the period of willow catkins flying. Statistics show that #10:00 to 16:00 in a day is the high incidence period of flying fox#, you need to remember the four-character motto: hide, cover, defend, clear. If the flying flakes accidentally get into the eyes, do not rub it with your hands, but rinse it with water. (China Weather)
