Article of the Day
Black Slave's Cry to Heaven was a 1907 stage play performed by the Spring Willow Society, a Chinese student troupe, in Tokyo, Japan. Adapted by Zeng Xiaogu from a translation of Harriet Beecher Stowe's novel Uncle Tom's Cabin, the play focused on the experiences and eventual escape of two slaves, Eliza and George, after killing several of their pursuers. Modified to allegorically call attention to the experiences of Chinese migrants in the United States, Black Slave's Cry to Heaven was innovative in its use of spoken dialogue and realistic set designs. Performed twice at the Hongō-za Theatre, the show was well received by critics and audiences. Although its script has been lost, the play has inspired subsequent works. Due to its technical innovations and nationalist themes, Black Slave's Cry to Heaven has been canonized as the first modern, Western-style Chinese drama. (Full article...)

Why you should extend your general knowledge:
There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.
As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
