Why did people in the past want to travel to the East? ! ? !

In the modern history of China, farmers from North China moved to three northeastern provinces. Guandong refers to the area east of Shanhaiguan, also known as the area outside Shanhaiguan. It turned out to be the "land of Longxing" in the Qing Dynasty, which was briefly opened in the early Qing Dynasty. In the seventh year of Kangxi (1668), a closed policy was implemented, resulting in a large number of no-man's land in Northeast China. 1860, in the face of tsarist Russia's occupation of the northeastern territory of China, General Tepkin of Heilongjiang wrote to the imperial court, calling for banning land reclamation and encouraging immigrants, which was adopted. Therefore, landless or landless farmers in Zhili (now Hebei), Shandong and other regions have entered the northeast to reclaim wasteland. This process continued until the September 18th Incident of 193 1. Millions of farmers from Yamaguchi migrated to the northeast.
