The Mogao Grottoes, a renowned UNESCO World Heritage site in the city of Dunhuang, northwest China's Gansu Province, partially reopened on Sunday, ending its 108-day closure due to the COVID-19 outbreak, according to the Dunhuang Research Academy.

The reopening comes with a host of epidemic prevention measures. All visitors are required to reserve tickets ahead of their trips, and only 1,800 visitors are allowed each day, accounting for 30 percent of its tourist capacity.

Other safety measures include checking every body temperature, ID card as well as the health QR code on their smart phones. Travelers are also asked to wear face masks throughout their visit, keep a distance of 1.5 meters from others, and sit separately when taking the shuttle bus. 

All medical workers from across the country are offered free tours at the tourist site till the end of the year to show gratitude. 

Located at a strategic point along the ancient Silk Road, the Mogao Grottoes is noted for a rich collection of over 1,000-year-old Buddhist statues and 45,000 square meters of murals. Its historical and religious value is incomparable. 

Some parts of the tourist site, including the Digital Exhibition Center, will remain closed until further notice.
