魚 (yú) is the Chinese word for "fish." Fish are aquatic animals that live in water, including oceans, rivers, and lakes. They have gills for breathing and fins for swimming. Fish come in various shapes, sizes, and colors, and they play a crucial role in the ecosystem as both predators and prey. In many cultures, including Chinese culture, fish are considered a symbol of prosperity and abundance. They are often featured in art and cuisine. Popular types of fish include 鮭魚 (salmon), 鯉魚 (carp), and 金魚 (goldfish), each with its own significance and uses in different traditions.
