PX Mart, also known as Quan Lian Welfare Center, is one of Taiwan's largest supermarket chains, and its in-store call for checkout support became a widely recognised phrase across Taiwan. The Mandarin announcement 請支援收銀 is heard daily by shoppers, making it instantly familiar and easy to parody. Online, the clip spread through meme videos and Crayon Shin-chan edits, where the polite store broadcast is reused as a humorous distress call. Its popularity continues because almost every Taiwanese viewer recognises the sound immediately.
