A thick fog continued to shroud central and eastern parts of China Thursday, leading to flight delays and expressway closures.

It was the second day that China's transport network was affected by the heavy fog, which reduced visibility to less than 10 meters in extreme cases.

Fog shrouds the city of Hangzhou, capital of east China's Zhejiang Province, Nov. 26, 2009. City traffic and flights are interupted due to the fog. (Xinhua/Yue Deliang)
