The bat in Taoism is a symbol of happiness and longevity, as contentedness is necessary for a long, healthy life. Further, the bat travels by night or "keeps to the yin," never exhausting its energy through yang activities and thus maintains longevity. Carved from very hard, high-quality bamboo, these locally-made bamboo spoons or chashaku are very nice. Used for shuffling leaves from your scoop into the teapot, cleaning the pot, unblocking the spout and moving leaves around within the teapot during a tea session. This utensil comes in handy more often than one might imagine.
