koreanfestivals1-6, Exercise 1: Kinds of ancestral rite

Model answer (any three):

- Gijesa: a memorial service on the anniversary of an ancestor's death, performed for up to five generations in the eldest descendant's house.
- Charye: rites on Seollal and Chuseok.
- Seongmyo: visits to the tombs, trimming the grass, offering food, fruit and wine, and bowing.
- Myosa / sije: rites at the tomb site in the tenth lunar month for ancestors five or more generations removed.

"Charye is also known as jesa" (Chuseok article) treats the two words as the same; "charye is one kind of jesa" (Jesa article, where jesa is the general word and charye, gijesa and others are kinds) says they are not. The safe wording is that jesa is the general word for ancestral rites and charye is the holiday kind.
Oddity: the Jesa article describes charye as "tea rites held 4 times a year on major holidays (Korean New Year, Chuseok)", but names only two holidays.
