Is there really a Zhu Kaishan in history?

There really is Zhu Kaishan in history. Gao Mantang, the screenwriter of TV series "Braving the Guandong", revealed that his third uncle and fourth uncle set out from Qingdao to brave the Guandong, and the prototype of Zhu Kaishan in "Braving the Guandong" was his third uncle and fourth uncle.

Background introduction:

From the early Qing Dynasty to the founding of New China, due to natural disasters, wars and other reasons, a large number of poor people in North China struggled to survive in the Northeast. In this immigration tide, Shandong is the home of the vast majority of people, and 20 million Shandong people have set foot on the vast and resource-rich land of Kanto. This rare and large-scale immigration phenomenon is called "crossing the Kanto". The 53-episode TV series "Going East" reflects this history.
