Sinuijuball is a cityball of North Koreaball. Sinuijuball shares borders with Chinaball. Sinuijuball was named after Uijuball (Sin means new, Sinuiju=New Uiju). He was the temporary capital of North Koreaball during the Korean War.
There's something to add.the "Real Sinuijuball"is not like what the picture shows.The ball on the picture is actually "Sinuiju SARball".North Koreaball set this SARball in Sinuiju to promote the cooperation with Dandong(Kanji:丹东（東）),Chinaball.
