Post-90s prefer sharing their supermarket shopping experiences through photos on social media rather than just words. An analysis of 500 Weibo posts found that more than 85% included pictures and over 42% showed off products they purchased. This "adult-buying" and displaying of purchases caters to a "show-off" culture. Most items bought are snacks, fueling this exhibitionist behavior, especially for students. Marketers should take note of this show off culture and how visual social platforms like Wechat could be effective for observing post-90s consumers.
