Chin Yu Min and the Ginger Cat

Chin Yu Min, a haughty and frivolous rich woman in a fictitious Old China, must mend her ways when her husband dies and her money runs out. She meets a ginger cat who fishes so well with his tail that she recoups some of her fortunes from selling his catches. When he disappears, Chin Yu Min is so distraught that she humbles herself enough to ask her neighbors for help.
