But do Chinese students love mobile technology enough to scan a QR code every time they want to take a shower? Hunan’s Changsha University of Science and Technology rolled out a new shower system, according to local media reports . It requires that users connect their phones to a smart water meter via Bluetooth. Then they have to scan a QR code before they shower, and scan again after they finish. It’s supposed to allow the university to know how much to charge students for water. And they say it means students don’t have to juggle too many access cards. (But it also probably means they should have a waterproof phone.) But the system was blasted by local media and Weibo users. Many on social media pointed out that their schools make students download too many different apps already, for classes, for food, and now even for showers. “Why don’t they put one on the toilet as well?” one Weibo user says. In fairness to the schools, the push to add technology is part of the government’s push for a smart campuses, even down to assigning roommates with recommendation algorithms. Around 60,000 schools -- roughly one in every four in the country -- are trialling the use of AI software to grade student homework . Some are even installing facial recognition cameras in classrooms to analyze students’ faces... to see if they’re dozing off. The new shower system is allowing people online to take a jab at one common problem among Chinese app makers: Gathering too much information.
