The story behind the Crystal Tree is that a heavenly fairy, Shang Ziyie, travelled to Earth with the intents to marry Chooi Wen Lui, a small village commoner. Because they had little money, the fairy fostered a magic tree, which created coins. It provided her family with the means to survive, and also assisted the other villagers when they gave it a shake. In modern days, a small Crystal Tree is displayed in homes and offices, to signify a steady profit and everlasting financial support.
