Xi'an, the capital city of northwest China's Shaanxi province, is to install a massive "sky screen" in May.

The 2,800-sq-m LED screen is the largest in northwest China, worth some 60 million yuan ($9.52 million).

The sky screen, which will be in the south square of the Dayan Pogoda, is similar to that at The Place Mall in Beijing.
