Normally the Queen of Hearts (qi) has her banner (旗) hanging on the top of the watchtower (其) just inside the space station's entrance (Ø2), but today a strange banner (旗) with a square (方) on it is hanging there instead. The Queen of Hearts wants to go up there to get the banner down, but somehow her key (𠂉) doesn't open the door anymore.
