In a bid to further step up the precautionary measures against the COVID19 pandemic, three major sightseeing spots in Shanghai, the Oriental Pearl TV Tower, Jinmao Tower, and Shanghai Center were closed to tourists starting from Monday, after an 18-day operation. Authorities will notify the new date of opening at a later time. Tourists, who have purchased tickets in advance, can get a full refund through the original ticketing platform. Photos: Yang Hui/GT
