While “computer” is a universal modern concept, its role and perception in China have a unique context. China's digital revolution happened at a breathtaking pace. For many older Chinese, the 电脑 represents a massive leap from a non-digital world to a hyper-connected one within a single generation. In the 2000s and early 2010s, internet cafes, or 网吧 (wǎngbā), were bustling social hubs where young people gained their first access to the internet, played games, and socialized online. The 电脑 was the gateway to this new world. A key difference compared to the West is China's “mobile-first” trajectory. While personal computers are common in offices and for specific tasks like gaming or design, many Chinese people, especially the younger generation, perform the majority of their daily digital tasks—shopping, paying bills, social media, watching videos—on their 手机 (shǒujī - mobile phone). Therefore, while a Westerner might assume “doing work” or “going online” happens on a laptop, in China, the default device for these activities is often a smartphone. The 电脑 is still essential, but it doesn't hold the same monopoly on digital life as it once did in the West.
