What does the "division of states" mean during the Shang Dynasty? How were the kings of the Shang Dynasty named? Are there any rules?

China has a long history, and the mysterious Shang Dynasty went through three major stages. The first stage is "Early Shang"; the second stage is "Early Shang"; and the third stage is "Late Shang". So what does the "division of territories" mean during the Shang Dynasty? To put it simply, the Shang Dynasty divided it The ruling area is divided into two parts: inside and outside. Kinei is the part directly ruled by the Shang royal family, and Kinwai is the area where many Fang kingdoms are distributed. In some relatively remote mountainous and forested areas between Fang states and in relatively remote areas outside Fang states, there are scattered ethnic minority tribes with uneven development. This is the basic outline of the areas ruled by the Shang Dynasty.
