Shanghai's tourist attractions have been ordered to take strict COVID-19 preventive measures, including a cap on visitor numbers, over the Qingming Festival holiday. The Shanghai Administration of Culture and Tourism released a list of holiday activities across the city on Saturday, while saying strict COVID-19 preventive measures must be imposed. All A-level tourist attractions in the city should keep the number of visitors below 75 percent of their maximum capacity, and ensure all visitors have their temperature measured, health QR code checked and wear masks, according to the administration. Reservations are encouraged.
