First of all, Shandong has been called "Tiqi" or "Sanqi" since ancient times, and the vassals who were sealed here were generally called Wang Qi. But since the Qing Dynasty, the abbreviation of Shandong has changed from "Qi" to "Lu".

During the Spring and Autumn Period and the Warring States Period, Shandong mainly included Qi and Lu. Because Qi State is much bigger than Lu State, Qi State is generally called Qilu Land after the former Lu State.

Although Qi and Lu in the Zhou Dynasty were both big countries, they took completely different paths. Qi is a typical marine civilization. With the benefit of fish and salt, we will vigorously develop handicrafts and commerce and make Qi a military power.

In the end, Lu became the most orderly country among the vassal States.
