Over 10,000 tourist attractions across the country had been reopened to the public by Monday, said Liu Kezhi with the Ministry of Culture and Tourism at a press conference.

During the upcoming holiday, reopened tourist sites should reach no more than 30 percent of their maximum visitor capacities, and visitors are encouraged to reserve their tickets in advance, Liu said.

Tourist sites should also make sound arrangements of tour routes to ensure visitors' safety and prevent the gatherings of crowds, Liu stressed.
