As part of a light show, hundreds of drones lit up the night sky in Shanghai. The culmination of the display was the creation of a gigantic QR code, which represented China’s thriving digital economy and growing consumer culture. In China, QR codes are widely utilized for various reasons, including connecting friends on messaging applications, making payments at markets and restaurants, and donating money to charitable organizations.
The Chinese video-streaming business Bilibili put on a light show featuring an illuminated QR code that served as an airborne billboard advertisement.
