A group of egrets ushered in the factory area, adding a different kind of fun to this summer. It is understood that this group of egrets is one of the country's "three haves" protected animals (terrestrial wild animals with important ecological, scientific, and social values). Egrets live in groups, and they have very strict selection and requirements for the living environment. They are also known as the "ecological inspector" of nature. This group of egrets chose this place during their migration, stopping to look for food and rest.
