BEIJING — With nearly 70 percent of scenic spots in China gradually reopened, a series of measures will be taken to address epidemic risks during the upcoming five-day May Day holiday, a Chinese official said on April 30.

Scenic sports across the country are asked to implement a reservation system to receive visitors at staggered time periods while controlling the daily number of visitors to no more than 30 percent of their maximum capacity during the holiday, said Minister of Culture and Tourism Luo Shugang at a press conference.

Targeted measures will be put in place where tourists tend to gather such as restaurants and entrances to avoid gatherings and keep social distancing, the official said, adding that tour routes are also suggested to be optimized.

Ventilation and sterilization in and around enclosed buildings, public areas, playground equipment and catering places should be implemented in a timely manner, together with strict epidemic control measures for visitors such as checking temperatures and health codes, Luo said.

Tourist attractions are also asked to formulate emergency response plans and conduct drills to enhance the capability to deal with emergencies, Luo said.

"Safety is the bottom line," Luo said, stressing that the ministry has required travel agencies and online travel enterprises, as well as scenic spots, to carry out safety assessments on travel products and routes, including the qualifications of tour buses and drivers and safety checks on amusement facilities.

Joint efforts will be made across different sectors including public safety and transport to strengthen supervision over the tourism market, Luo said.

Luo added that visitors should learn about related regulations and epidemic control measures of their destinations in advance, particularly ticket reservations and visiting at staggered time periods.
