King of China
King Wu followed his victory by composing the Great Martial Music (大武樂). A poem was also made singing praises of his victory that is recorded in the Book of Poetry, Da Ming (大明). The Shi Qiang pan and Yi Zhou Shu imply that King Wu continued his campaign into the Dongyi to eliminate further threats, including the Cuo (虘), Biao (髟), and Yitong (夷童).
Oracle bone evidence from Zhouyuan (周原), Qishan County, seems to imply that King Wu of Zhou had communicated with Shang prince Wu Geng at some point shortly after the Battle of Muye:
…巳，王其乎更，厥父陟。
On the __si day, the King may call Geng; his father then/had ascended.
Lu Guoquan (路国权) and Wang Junmei (王君美) interpret the line geng (更) as being the geng (庚) in Wu Geng's name, using paleographic evidence from Liezi. They furthermore note that the zhi (陟) is a euphemism for Di Xin's death, using evidence from the Book of Documents. The scholars therefore believe that Wu Geng was away from Yin at the time and King Wu summoned him to give the news and organise what to do thereafter.
Familiar with Shang ritual culture, within a year, King Wu performed a ritual in Yin. He also made a sacrifice to King Wen of Zhou around this time, which is detailed on the Tianwang gui, thought to date to King Wu's reign. Furthermore, Wu Geng, also known as Lu Fu (禄父) and one of the heirs to the Shang throne, was allowed to preserve his state and continue Shang religious practices. This subdued state would later become the state of Song under Weizi Qi.
After performing the rituals, King Wu moved his court from Feng to the nearby Hao, leaving the older settlement to serve as a site for ancestral temples and gardens. He granted many 'feudal' states to his 16 younger brothers and to clans allied by marriage, which the Bamboo Annals records as having occurred at least a year after his victory. Shuowen Jiezi traces two characters to this precise period, specifically Yu (邘) and Xun (郇), which were granted to his sons. He also enfeoffed Jiang Ziya at Yingqiu, which became Qi; Duke Dan of Zhou was enfeoffed in Qufu, becoming Lu; the Duke of Shao was enfeoffed in Yan, and then his brothers Shu Xian (叔鮮) in Guan and Shu Du in Cai (叔度). The Zuo Zhuan lists Yu (邘), Jin, Ying, and Han (韓) as additional states that were founded by King Wu. Despite his victory, King Wu did not fully understand why Shang had fallen, and upon asking Jizi two years later, he was too uncomfortable to say.
The enfeoffments of Shu Xian and Shu Du, as well as another brother in Shu Chu of Huo (霍叔處), were not arbitrary. These locations were all close to the state of Song, allowing for continuous monitoring of the deposed Shang royal family. It is for this reason that these individuals were called the "Three Guards" (三监). He also allegedly enfeoffed Jizi in Chaoxian (朝鮮), which would become Joseon, Korea.
The Bamboo Annals record King Wu hunting in Mount Song and moving the Nine Tripod Cauldrons to Luo (洛) in his 15th year. In the next year, Jizi came to his court and Pugu (蒲姑) was annihilated. In his final years, he ordered Wang Shizi to recite at his court, and he died in winter, at 54 years old.
