Literally, this term refers to “colorful carp,” a freshwater fish of the cyprinid family found in China more than a millennium ago. The species was then introduced into Japan, where, from the 18th century onwards, the common carp was bred into the ornamental variety known as “koi” — or more accurately “nishikigoi.” The colorful carp, known for its beautiful colors and longevity, has been a popular feng shui fish in China, believed to bring good fortune to its keepers. Online payment service provider Alipay recently held a lucky draw, picking randomly a winner for its numerous prizes including free overseas tours and luxury hotel stays throughout next year. Calling the winner “Chinese colorful carp” helped promote the popularity of the term, which is now another word for “symbol of good luck.”
