Why is Shandong referred to as Lu instead of Qi?

Shandong is the abbreviation of Lu rather than Qi for the following reasons:

1, the cultural influence of Zhou Li

After the destruction of the Shang Dynasty, Zhou Wuwang's younger brother, Duke Zhou, was sealed in the state of Lu, which was always regarded as a country that respected righteousness and valued ceremony.

2. The contribution and influence of Confucius

Lu also produced Confucius, a figure who influenced China for thousands of years. In fact, Qilu's contribution and influence to Shandong is great.
