Dream of the Red Chamber, also called The Story of the Stone, composed by Cao Xueqin, is one of China's Four Great Classical Novels. It was written sometime in the middle of the 18th century during the Qing Dynasty. It is considered a masterpiece of Chinese literature and is generally acknowledged to be the pinnacle of Chinese fiction. "Redology" is the field of study devoted exclusively to this work.
Red Chamber is believed to be semi-autobiographical, mirroring the rise and decay of author Cao Xueqin's own family and, by extension, of the Qing Dynasty. As the author details in the first chapter, it is intended to be a memorial to the women he knew in his youth: friends, relatives and servants. The novel is remarkable not only for its huge cast of characters and psychological scope, but also for its precise and detailed observation of the life and social structures typical of 18th-century Chinese aristocracy.
