Ceremony at Korean cemetery. We have came with professor Kim to the grave of his parents.
"Traditional Korean graves are mounds of earth usually on rural hillsides in scenic locations chosen as auspicious for the future fortunes of the family. At Chuseok, the fall harvest moon festival and at Lunar New Year, families go to the graves of their ancestors (male line) to continue the age-old custom of showing filial piety and respect." http://www.korea4expats.com/article-people-culture.html
