`跟风` is an extremely common term used in everyday, informal conversation.
Social Media: This is the primary domain for `跟风`. People `跟风` viral challenges, use popular slang or filters, or copy the photo styles of influencers. Example: “Everyone on Douyin (TikTok) is doing that dance; it's a total `跟风` phenomenon.”
Consumer Culture: This refers to buying a product (like a specific brand of milk tea, a new phone, or a “hot” fashion item) just because it's popular. People might accuse their friends of `跟风` if they buy something without seeming to genuinely need or like it.
Business Strategy: The term can be used to criticize companies that lack innovation and simply copy a successful business model. For example, when one bike-sharing company succeeded, hundreds of `跟风` companies appeared.
Connotation: The connotation is almost always neutral-to-negative. Calling someone a `跟风者` (gēnfēng zhě - a trend-follower) is a mild insult, implying they are unoriginal.
