다 내려가다

go up and down

Six of these lines are the same paired phrase, went up and came down, used for anything that keeps oscillating: a price flow, a market cycling and rising again, stairs you climb and descend to change trains. The 다 ending here marks the switch from one movement to the other, which is why the two verbs come as a pair. One line is a false match, where the same syllable is really the particle for than.
