Why did so many Shandong people go to Guandong, and the Shandong dialect was conquered by Manchu?

Northeast China is the birthplace of Manchu people, and Shandong people came to Northeast China by stages, gradually changing their language and living habits.

In fact, Manchu people are also influenced by the living habits of foreigners and have changed their way of life. This is mutual, not a simple change.

In fact, since the Ming Dynasty, some people have ventured into the Kanto and gradually merged into the Jurchen nationality. In the late Qing dynasty, it was just that the immigration action was bigger. In the early Qing dynasty, a considerable proportion of jurchen came from inside Shanhaiguan pass. A careful study of Manchu surnames shows that there are many "certain" Jiashi, and most of these people are from Shanhaiguan Pass.
