Basically the city of Andong is famous for many things, like masks and chicken and stuff. Every year their festival attracts visitors coming to celebrate the cultural diversity of the area. I have never been to the Andong Mask Festival, I don't know why you asked about it.
Thousands of hand made lanterns lined the city-splitting river in Jinju, accompanied by scores of larger lanterns floating on the water itself.
You could even make your own lantern. All you had to do was create a sketch and local art students helped bring your vision to fruition. Many people made stars, hearts, or symbols of Korea. A friend and I decided to make a "crab-baby," pictured below.
Back to the drawing board. Next we proposed a kimbap airplane. The same art student gave us the go-ahead, but we couldn't finish the wings in time so instead just created a green cylinder.
