Yuanyang, sometimes also called Ying Yong, is a popular beverage in Hong Kong, made of a mixture of coffee and Hong Kong-style milk tea. It was originally served at dai pai dangs (open space food vendors) and cha chaan tengs (cafe), but is now available in various types of restaurants. It can be served hot or cold. The name yuanyang, which refers to mandarin ducks, is a symbol of conjugal love in Chinese culture, as the birds usually appear in pairs and the male and female look very different. This same connotation of "pair" of two unlike items is used to name this drink.
