evidence: Claim: "15-minute cities in China — each neighborhood zone is separated by a fence, with an entrance gate being guarded. If you want to get in or out of your zone, you need permission, and a FACE SCAN," is a claim made by a TikTok user(archived version of the original post that was deleted here). [...] The video suggests — as other social media posts do — that the 15-minute city concept has already been implemented in a strict way in Chinese cities. [...] Regarding the 15-minute city model, Shenzhen authorities do plan to implement ideas from this urban planning concept. Shenzhen local government announced it had set up so-called "15-minute domestic service circles." But we could find no hints that fences or gates are part of the implementation.
