The logo has evolved from the cursive script of the Chinese character "外" (meaning: aliens);

Circle: refers to a country or specific region:
Points: representing alien invasive species; point outside the circle means to prevent alien invasive species from outside the country; the point in the circle means to control the alien invasive species within a certain range;
Green: means environmentally friendly, making the earth greener

The general idea is to develop a technology system and platform for environmentally friendly species and the prevention and biocontrol of alien invasive species, building a green "Great Wall".
