I'm with my Lao Ye (maternal grandfather) trying to get back into our building.  Neither of us have keys so we buzz a friend in building & she lets us in.  Just then, mom shows up and I help haul her bag up to the 7th floor.  I see Lao Ye open the door (turns out it was unlocked all along).

Later, mom & I and korean girl are going to some tourist destination in Korea.  We walk through some buildings & past many fancy restaurants.  After a while of wandering, we get our Korean friend to ask for directions.  We finally get to the docks and look for the clue.
