What does it mean that Chu Shi is regarded as the dividing line?

In fact, Chu Shi's star on the dividing line means that Chu Shi's star is particularly bright in the constellation Minor, which corresponds to the dividing line.

Division is that ancient astrologers use the changes of astronomical phenomena to predict the good or bad of the world, and correspond the starry sky area with the countries on the ground. Secondly, the constellation * * * has four stars, and the first one is "the first star Chu Shi". Therefore, the whole sentence is that the Chu Shi star in a few micro-constellations is particularly bright, just corresponding to the dividing line.

Appreciation of the original sentence:

According to the Records of Scenic Spots in the Ming Dynasty, "Chu Shi Star was discovered in the ninth year of Sui Dynasty (AD 589), so it was established as a state." Therefore, it was named "Chuzhou" when the capital was established in 589, and Dakuo Mountain opposite Xiamen River was renamed "Shaoweishan".

Although the name of Chuzhou has been changed to Zhangzhou, Yongjia County and Jinyun County. Historically, the name of Chuzhou was changed from the 14th year of Emperor Taizong (AD 779) to the end of Qing Dynasty, which lasted for more than 30 years1/kloc-0. This star is the "Chu Shi Star" in Shao Wei's constellation.
