In Internet slang, a trollis a person who sows discord on the Internet by starting arguments or upsetting people, by posting inflammatory, extraneous, or off-topicmessages in an online community (such as a forum, chat room, or blog), either accidentally or with the deliberate intent of provoking readers into an emotional response or of otherwise disrupting normal on-topic discussion.
This sense of the word troll and its associated verb trolling are associated with Internet discourse, but have been used more widely. Media attention in recent years has equated trolling with online harassment. For example, mass media has used troll to describe "a person who defaces Internet tribute sites with the aim of causing grief to families.
article from wikipedia (http://en.wikipedia.org/wiki/Bao_Zheng)
Bao Zheng (包拯; 11 April 999 – 20 May 1062), commonly known as Bao Gong (包公, "Lord Bao"), was a government officer during the reign of Emperor Renzong in ancient China's Song Dynasty. During his twenty five years in civil service, Bao consistently demonstrated extreme honesty and uprightness, with actions such as sentencing his own uncle, impeaching an uncle of Emperor Renzong's favourite concubine and punishing powerful families. His appointment from 1057 to 1058 as the prefect of Song's capital Kaifeng, where he initiated a number of changes to better hear the grievances of the people, made him a legendary figure.
Nicknamed "Clear Sky Bao" (包青天), Bao Zheng today is respected as the cultural symbol of justice in Greater China. His largely fictionalized gong'an and wuxia stories have appeared in a variety of different literary and dramatic mediums, and have enjoyed sustained popularity.
