Introduction to the Jurchen Ancient Well: In Juercha City, there are still many traces of Jurchen Jurchen. In just over a hundred years since they came to the banks of the Suzi River and at the foot of Yantong Mountain, they crossed over from clan society and slave society, quickly entered feudal society, and became the masters of the Qing Dynasty who unified the world. The rapid development of Jurchen society provides people with a rare precedent of an ancient nation moving from backward to advanced and developing rapidly.
