周文王
Nangong Kuo (; fl. 11th century BC) was a top official of King Wen of Zhou during the late Shang and early Western Zhou dynasties. In the "Jun Shi" (君奭) chapter of the "Classic of History", the Duke of Zhou names him as one of the five key advisers of King Wen, together with Guo Shu, Hong Yao, Tai Dian, and San Yisheng. After King Wen's death, Nangong Kuo became a key adviser of his son King Wu.
