What is the ancient "Kanto" in China now?

Generally speaking, it refers to two places. Before the Ming Dynasty, generally speaking, Guandong only refers to Hanguguan or Tongguan East, including most of the North China Plain areas such as Henan, Hebei and Shandong.

After the Ming Dynasty, the Qing Dynasty, especially the late Qing Dynasty and the early Republic of China, mostly refers to the northeast area east of Shanhaiguan, including Heiji and Liaoning provinces and eastern Inner Mongolia. For example, the TV series "Go East", which is very popular now, is the story of Shandong people migrating to the Northeast. Tell the story of a great immigration tide at that time.
