Koreans have enjoyed drinking tea for a long time and developed their own tea ceremony. Through the ceremony people meditate and nourish their virtuous spirit. According to the Chronicle of the Three Kingdoms, tea was first introduced into Korea during the reign of Queen Seon-deok in Shilla, and the culture of tea drinking was highly developed in Goryo. In Joseon, it was not as popular, but during the later years of Joseon, scholars and artists like Jeong Yak-yong, Kim Jeong-hee, and priest Choi enjoyed drinking tea and developed the culture. Tea leaves are picked in early spring and preserved for later use. Koreans make tea by pouring water of 60~70 degrees Celsius on tea leaves or adding the powder in water. Usually they make tea three times out of the same leaves, saying the first one is for scent, the second for taste, and the last as medicine. Tea must have a mild taste and scent, and those who enjoy tea say that there are five pleasures in tea drinking: the sound of water boiling, the warmth of the tea cup, its color, its taste, and its scent. Tea is good for making your mind clear, improving memory, preventing cancer, purifying the body, and lowering cholesterol. There are a lot of tea clubs in Korea, which develop the tea culture in Korea.
