Brief introduction to the road of blood and tears

Americans euphemistically call the process of Indians being forced to flee their homes "Indian immigrants." In fact, this process is to liberate the land between the Appalachian Mountains and Mississippi, let whites grow cotton in the south, grow grain in the north, expand outward, develop immigrants, build canals, build railways and emerging cities, and build a huge empire across the continent and connecting the Pacific Ocean. It is impossible to accurately calculate how many Indians paid the price of their lives in this process, so the process of forcing Indians to move westward in the United States is called the "road of blood and tears" of disaster.
