Hushan Great Wall

[2] Archives of Andong (Dandong) county put the wall's location to the north of the Ai River (叆河), in the Hushan area.

A series of surveys in late 1980s and early 1990s led by architectural historian Luo Zhewen identified the ruins at Hushan as the site of the eastern terminus of this Great Wall section.

[4] The site of a historical city known as Posuo (婆娑) or Bakjak (泊汋, 박작) lies in close proximity at present-day Jiuliancheng, to the south of Hushan.

[5] On the other hand, North and South Korea academics show skepticisms on the historical existence of the Hushan great wall due to lack of evidence.

[6][7] Some South Korean archeologists and experts argue that the walls and fortifications were likely originally built by the allied Ming and Joseon to defend against Jurchen marauders to the north.
