What Is Three Squares and Four Corners?
Three Squares and Four Corners (sān fāng sì zhèng) is the basic structural perspective for interpreting a Zi Wei Dou Shu chart — the original palace plus its two trine palaces form the “three directions,” and adding the opposite palace forms the “four corners.” This article explains the geometric definition of Three Squares and Four Corners, why a chart must be read across four palaces rather than one, how to judge combined fortune and misfortune across the three directions and four corners, and the common misreading that “a bad original palace means the entire palace is bad.”
