Taiwanese people in Fujian have the habit of drinking tea, but also have a corresponding set of tea drinking utensils. Tea has caffeine, so there is a corresponding refreshing to wake up the role of the brain, but its main purpose is relax your mind, make you slow down, listen to your inner voice. I think, if you have the chance to travel to Quanzhou, Fujian, you need to have a taste of the Iron Mercy Goddess.
