Sitting at home, Wang Nan, a Dunhuang culture enthusiast in the eastern Chinese city of Qingdao, paid her first visit to the Mogao Grottoes via her smartphone.

"I was deeply touched by the breathtaking cultural relics, and I can chat with other visitors on the online tour. This is quite different from field tour," Wang said.

Amid the novel coronavirus outbreak, many Chinese scenic spots have been closed to avoid public gathering and reduce cross infections. Instead, they provide a satisfactory online touring experience for the country's vast number of stay-at-home visitors.

The Dunhuang Academy, which administers the Mogao Grottoes, in Northwest China's Gansu province, has been offering online exhibitions on various platforms, including its official website, social media platform WeChat, and video-sharing app Douyin, also known as TikTok.

The online grottoes touring programs on WeChat and media tool QQ attracted 5 million views in the first 10 days since their launch on Feb. 20, while short videos uploaded by the academy on Douyin has obtained more than 50,000 likes since Feb. 18.

By visiting the website "Digital Dunhuang," visitors can be immersed in the images of more than 4,430 square meters of murals across 30 caves. In early February, the mobile phone version of "Digital Dunhuang" was also launched.

The Mogao Grottoes are home to collections of Buddhist artwork -- more than 2,000 colored sculptures and 45,000 square meters of murals -- in 735 caves carved along a cliff by ancient worshippers.

It was first constructed in 366 AD For more than 1,000 years, it was a popular marketplace, travelers' stop, and a religious shrine on the ancient Silk Road.
