The city of Dandong lies on the border of China and North Korea separated by the 900-meter wide Yalu River. Taking the China-North Korea Friendship Bridge would take you right into Sinuiju, North Korea, if you have the right permission.
However, word has it that there’s a place upstream of the Yalu where it is only three or four meters across. The place is known as Yibu Kua (“a step across”) due to the fact that one could easily step into the other country by walking across the stones in the river. RocketNews24‘s Kuzo went to check it out.
