The report also concluded that authorities in southern China spent the most time writing micro blogs. Among Chinese provinces, East China's Jiangsu province contained the largest number of official micro-bloggers. By March 20, 279 government agencies in the province had set up micro-blog accounts.

East China's Fujian and Zhejiang provinces and South China's Guangdong province were also the places of origin for more than 100 official micro-blog accounts.

By taking into account the number of messages posted on the micro blogs and the number of followers each drew, the report listed the 10 most influential blogs maintained by authorities and by officials.

Among the top 10 were the public security bureaus of Guangdong and Hebei provinces and Beijing municipality. And Wu Hao, a senior publicity official in Southwest China's Yunnan province, and Zhang Chunxian, Party secretary of Northwest China's Xinjiang Uygur autonomous region, were among the officials who wrote the most influential micro blogs.

The report also found that 19 officials at the provincial level, such as provincial governors, wrote micro blogs online.

The report called on officials to try to improve their writing. "(The blogs) should unite an individual's style with authority and authenticity," Zhang said.
