yellow and red dragon hanging decor

This is 聯漁龍. Dragon boats are stored in such a structure when they are not in use. The 5th of May in the lunar calendar is the Dragon Boat Festival in which dragon boats are rowed for competition in the Aberdeen typhoon shelter nearby. Each dragon boat belongs to a different organization, such as fishermen from different districts, university teams, rowing teams, etc. The dragon head can be detached when not in use, e.g. during practice. The dragon head would be put into the slot for real races. It's not common to see the dragon head attached to the dragon boat like this during storage.
