Tea seems to make people clear. At first, I drank green tea latte because it was not sweet, but now I only drink pure tea. Tea  is a good aid to calm your mind. If you only drink tea, it will be hard  to calm down. But if you can drink the surroundings and surroundings  together instead of tea, you are already a calm person. tea = 차 Black tea = 홍차 Green tea = 녹차 White tea = 백차 Puer tea / Dark tea = 흑차 Ooloong tea = 청차
