Nature's light show attracts tourists to North China

Residents and tourists recently viewed the spectacular aurora borealis, or Northern Lights, in Mohe, Heilongjiang province, China's northernmost city.

Colors, mainly red and green, ripple alternately across the night sky at high latitudes. They appear as curtains, rays, spirals or flickers from horizon to horizon.

Auroras are caused by the earth's natural electrical fields in both the northern and southern hemispheres. The most famous is the aurora borealis, which appears in high-latitude regions of the Northern Hemisphere.

"I feel very lucky and excited," said Li Ke, a tourist from Shanghai. "I originally came here to enjoy the ice and snow. This was a really pleasant surprise."

Located at China's highest latitude, Mohe is one of the best places in the country to observe nature's light show. Numerous photographers come to chase the aurora every year. The city has experienced multiple occurrences since the beginning of this year.
