With severe smog continuing to shroud multiple regions of eastern China, some people are choosing to travel in an effort to escape the pollution.

A different view of Shanghai's smog. It's really difficult to imagine this is Shanghai Tower.

China's financial hub, has lost its glamorous skyline. Buildings on the other side of the Huang Pu river are barely visible.

Shi Hongli works at Shanghai Tower. He says the smog has never been this bad.

"I have been working for one year. I feel like I am working above the "clouds." Shi said.

This is the video shot by Shi's colleague on December 5th, 480 meters above the ground.

A shrouded city..

Meteorologist say winds will soon blow away some of the pollutants. But some residents can't wait.

Travel agencies are busy these days, with more people choosing to travel to escape the haze. Southern destinations such as Hainan Province are very popular.

"I want to go to Sanya. Sanya's air quality is better than here, and the scenery is also good."

Moving southwards, the situation is similar in the city of Fuzhou, which had good air quality in the past.

On Saturday, visibility was less than 50 meters. Many residents are worried

"I seldom experience such bad weather. These days' air quality is the worst of the past two years."

But experts say it's rare for Fuzhou, and it will not last long.

Starting from early this week, much of East and North China has been hit by smog. According to China National Meteorological Center, smog will persist in eastern China until Monday, though it will disperse in northern China on Sunday.
