The word "avant-garde" comes from the military field and is used to describe the vanguard troops on the battlefield. Later, it gradually evolved into the concept of art and culture.
In the field of art, "avant-garde" usually refers to those artistic schools or artists who do not stick to traditional aesthetic standards and rules, but take innovation and transcendence as the starting point. These works of art may contain some elements of adventure, challenge and even controversy, but they can often create unique visual and aesthetic experiences and have a far-reaching impact on the whole art world.
