Shared-bike operators in 60 central streets of Shanghai recently deployed workers to sterilize public bikes in the city on a daily basis. The move comes amid a wake of ongoing work resumption after the extended Spring Festival holiday. Besides, shared-bike usage rates are reportedly rising. The disinfection work is likely to focus on the regions near the railway line and transportation junction. On average, each worker has to sterilize over 2000 bikes per day.(Photos:Yang Hui/GT)
