The Folding Fan of the Oath of Mountains and Seas

Once upon a time, there was a person who danced like a giant on the stage. Once upon a time, there was a person who turned into bubbles through alms.

Once upon a time, there was a group of us who laughed at the suffering of all sentient beings. A cup of tea reflects a person's face.
