A gaiwan is a traditional Chinese tea cup, typically made of porcelain. It consists of three parts: a shallow bowl (the main body), a lid to cover the bowl, and a saucer to hold the base. The cup is often used for brewing and drinking loose-leaf tea, especially in gongfu tea ceremonies. Its white color emphasizes the clarity of the tea's appearance and allows the drinker to fully appreciate the tea's color and aroma. Its simple design provides a clean, elegant aesthetic for tea enthusiasts.
