Immigration to the northeast refers to the journey to the east. Specifically, it refers to Jilin, Liaoning and Heilongjiang provinces.

Social impact:

Nowadays, popular film and television works will inevitably modify or exaggerate The Journey to the West's influence, but it is undeniable that the real climax of The Journey to the West began at 1904.

1904 at the end of the Qing dynasty, the court was corrupt, and peasant uprisings continued everywhere.
