In the age of China social media, "DaKa"(visit an Instagrammable spot) has become a ritual. People seem to believe that a place is only truly visited once a photo has been taken at a "hotspot." The phenomenon of a public restroom by the sea becoming a popular destination for its "photo potential" is both absurd and common. People no longer care about the authentic experience of a place but rather if the photos look stunning and express a seemingly "unique" life attitude. KOLs (Key Opinion Leaders) and social media platforms act like tireless large model trainers, constantly reinforcing specific landmarks, slogans, and trends. Users flock to these "attractions," posing in identical ways and writing similar captions. This is a collective training of human behavior, where each person provides effective data for this immense model of imitation and production. Ultimately, both the producers and users of this content fall into a state of collective agnosia. The core of this "collective agnosia" is that when inauthentic content is over-packaged and repeatedly spread online, people gradually lose the ability to distinguish between reality and fabrication. This phenomenon is identical to the diagnostic challenge people face with AI-generated content flooding the internet. To reveal the power of this "collective agnosia," all photos in this work are sourced from non-AI-generated content on the Chinese social media platform Xiaohongshu. However, each photo possesses a strong AI-generated aesthetic. Through this, I explore the boundary between perception and agnosia.
