Someone’s mad…
Hushan, on the Chinese-Korean border, was identified as the eastern terminus of the Great Wall in 2009.
This section of the wall was excavated in 1989 and in 1992 a section of the wall was renovated by the Chinese and opened to the public.
The Korean academia alleged that the Chinese renamed the city from Bakjak to Hushan, then built the local section of the wall to diminish local traces of Goguryeo, the ancient Korean state which Koreans consider to have first built Bakjak (Hushan).
