What is the relationship between divination and the royal tribute of Shang Dynasty?

At that time, divination had become a profession. Not only did the tortoise shells of Shang royal family need to be classified and filed, but also divination itself was completely professional. Witches are the main group to master the culture, writing and religious divination of Shang Dynasty, and every profession they engage in needs strict professional training.

The royal tributes of Shang Dynasty were also called "ministers", "princes" and "junior ministers". Most of them have a technical expertise, or hold an important position in a certain aspect of state power, or are in charge of a certain aspect of business, and they are all state public officials with certain professional education.
