Meaning literally a "lidded cup", this is the authentic Chinese tea cup. Its functionality is pure. You place the tea leaves in the bowl, add water and then sip the tea from the bowl using the lid to partially obstruct the leaves from escaping. They are ideal for green tea since the porcelain absorbs the heat allowing for easy sipping. We have several - this being one of the prettiest. Try one - it changes the act of drinking tea to an art.
