Everyone had quickly settled on celebrating the Dragon Boat Festival together, and the house was filled with joy these past few days. The aunt and the eldest cousin's wife had brought home many colorful papers, which they cut out, and everyone folded them into calabashes before hanging them on tree branches.
As for why calabashes are folded during the Dragon Boat Festival, there are many legends, like the stories of Lu Dongbin from the "Eight Immortals Crossing the Sea" selling oil, and the tales of the Medicine King, among others. But they all dealt with averting disasters and resolving difficulties, and since these were unverifiable facts, they were treated as customary traditions.
