koreanfestivals1-9, Exercise 3: The Andong festival and sources

Model answer:

Found: an Andong International Mask Dance Festival is listed in the Andong article; the Andong Folk Festival is held in mid October; the Hahoetal article says the city hosts an international mask dance festival every October.
Not found: a Wikipedia article on it, a start year, a programme, visitor figures, or any statement of how it relates to the Hahoe village ritual.
Why the change: with so little documented, a case study of the festival would have been mostly guesswork, so the chapter covers the well-documented Hahoe mask-dance ritual behind it, says how little was found, and points to places to look.

Source and question (any reasonable pairing), e.g.: the festival's official site or the Andong city tourism office - when did the festival begin, and what does the programme include? Korea National Heritage Online - how is the Hahoe drama designated and who holds it? The Hahoe Mask Museum - where are the masks kept and how can they be viewed?
