koreanfestivals1-5, Exercise 3: Layers, borrowing and the solstice

Model answer:

Older Korean layer plus a Chinese one: Dano. The article describes an older spring rite (Mahan, Jinhan, passed to Silla, "it is said") that was syncretized with the Chinese Duanwu Festival during the Joseon period, adopting the name Dano and the exact date.
A day the article says was adopted: Chilseok, which originates from the Chinese Qixi Festival; the tale of the Cowherd and the Weaver Girl "was adopted by Koreans".
A name that outlasts its practice: Hansik ("cold food"); the article says the custom of eating cold food has disappeared, though tomb tidying remains.

Winter solstice (Dongji): red bean porridge (patjuk) with glutinous rice balls (saealsim). Beliefs (any two): the red colour drives off baneful spirits; the porridge was once sprayed on walls or doors to ward off bad ghosts; the number of saealsim often equals the eater's age; in the early Goryeo and Joseon people in financial difficulty settled debts and enjoyed the day. The solstice is also called "Small Seol".
