6. A 360-degree virtual tour of Terracotta Army

The Emperor Qinshihuang's Mausoleum Site Museum in Xi'an, capital of Northwest China's Shaanxi province, has rolled out a virtual tour of its world-famous Terracotta Army, enabling visitors to enjoy a 360-degree panorama of the eighth wonder of the world from the comfort of home.

With a 20 billion-pixel resolution panoramic view, visitors can take a "walk" among the warriors in two of the four sites, pits one and three, to have a closer look than would be possible in person at the more than two-millennia-old statues.
