Why do you love doing physical work?
Putting on his blue overalls, Wang Yanbing became an unremarkable cashier at the exit of the shopping area of a self-service fresh food supermarket in Beijing. Now working as a cashier in this mall, most of the time you don’t need to bury your head in scanning codes and typing on price keyboards. Supermarkets are equipped with self-checkout machines, and cashiers only need to stand near the checkout machines to supervise customers' self-checkout and provide assistance to customers in need.
