Info: In spring, willow trees in the north start growing leaves. This causes problems with willow flakes, which can get everywhere. This footage was filmed by Wang Ziyu.
Flying willow flakes can cause many people to have allergic reactions. These reactions can include rhinitis, sinusitis, conjunctivitis, allergies, asthma, and other symptoms. The weather can last for up to a month, so the willow flakes that fill the sky are a problem for many people.
