Nangong Kuo was a top official of King Wen of Zhou during the late Shang and early Western Zhou dynasties. In the "Jun Shi" 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.
Nangong Kuo was the founder of a major aristocratic lineage of the Western Zhou. His eldest son probably died early, and his second son Nangong Mao inherited his title. The famous Da Yuding, now a national treasure of China, was cast by Nangong Kuo's grandson Yu, and dedicated to him. The bronze inscription on the vessel traces Yu's lineage back to Nangong, who is identified by scholars, including Li Xueqin and Li Feng, with Nangong Kuo. Inscriptions on other unearthed bronze vessels indicate that during the late Western Zhou period, the Nangong lineage continued to produce important military leaders like Nangong Liu, and civil administrators such as Nangong Hu, Supervisor of Land. Inscriptions on excavated bronzes from the tombs of the marquises of Zeng in Hubei Province indicate that Kang of the Nangong clan was enfeoffed with the Zeng state by either King Cheng or King Kang of Zhou. Kang, the first Marquis of Zeng, was either Nangong Kuo's son or great-grandson.
In fiction
Nangong Kuo is a character in the Ming dynasty classic novel Fengshen Yanyi. In this novel, Nangong Kuo is a renowned general that had loyally served under Ji Chang of Mount Singing Phoenix. Nangong generally seems to be more of an aggressive individual, and will rush to rather impulsive conclusions at times. Following the death of Ji Chang's first son, Bo Yikao, Nangong would swear eternal revenge against King Zhou. Due to Nangong's continuous lust to attack Zhaoge at any possible moment, San Yisheng develops a negative liking towards him. Following King Wen's attack upon Tiger Town, the capital of Chong Houhu, Nangong is the first to charge the gates of the capital. When General Huang Yuanji stands before him, Nangong yells, "Huang Yuanji, you small potato, get out of my way! I only want to fight the real Chong Houhu himself!" With these words, Nangong, with his great knife, cuts Huang Yuanji down with relative ease. Later on following General Zhang Guifang's attack upon Phoenix City during the Huang Feihu retrieval arc, Nangong duels it out against Vanguard Feng Lin. After defeating Feng with great ease, he is captured by Feng's magic technique; only later due to Nezha's assistance would he be saved.
