Why did Wu Ding choose Fu Shuo as the subject?

BC 1250, King Wu Ding of Shang Dynasty broke through all kinds of obstacles and took Fu Shuo, who was born a slave, as an example. Wu Ding's move not only found a talent who helped him achieve great things, but also created Fu Shuo, a famous minister of Shang Dynasty who was equally famous with Yi Yin. Before Wu Ding acceded to the throne, he paid great attention to visiting talents.

Once, when he came to Fuxian County, he saw a group of slaves who were punished for hard labor after committing crimes were repairing roads. Wu Ding talked with a slave named Fu Shuo and found that he knew all about state affairs and plans for governing the country. He was deeply impressed and was in the mood to help him govern the country. Wu Ding claimed to have dreamed of a saint. It is said that the saint's name was that he sent people to look everywhere and finally found him among criminals. Yin customs believe in ghosts, and as prime ministers, nobles dare not object. At that time, the nobles were corrupt and useless. Wu Dingju took photos of Fu Shuo and sent some politics to ease the slave confrontation, so that the business could be revived.
