EDIT: a quote about ROTK from wikipedia.org - It must be understood that one of the greatest achievements of the Romance of the Three Kingdoms is the extreme complexity of its stories and characters. The novel is studded with numerous "mini-stories", many of which could be developed into full-length novels in their own right (the Battle of Red Cliffs and the treatment of Guān Yǔ by Huá Tuó being two examples). As such, the following effort only serves as a very high level summary of the entire story.
A funny note, "Today Guan Yu is still widely worshipped by common folks. In Hong Kong, a shrine for Guan Yu is located in each police station. Though by no means mandatory, most Chinese policemen worship and pay respect to him. Seemingly ironic, members of the Triad gangs and the Hung clan worship Guan Yu as well. This exemplifies the Chinese belief that a code of honor, epitomized by Guan Yu, exists even in the underworld."
