    Tea is an important part of Chinese tradition. Tea has very close relationship to Chinese culture.

    It is said that Chinese tea was discovered by King Shen Nong. People say that he lived 5，000 years ago. One summer day, while he was visiting a faraway part of his country, he felt very thirsty. The servants began to make water hot enough for him to drink. Dried leaves from a near plant fell into the water. The king drank some, and found it could make him feel less tired. Also as a scientist, Shen Nong was interested in the new drink. And so, tea was created in 2737 BC.

    Drinking tea has many advantages. It makes people feel less tired, clears heat inside the human body and helps people become slimmer. As you add a cup of tea to your daily life, please check the following helpful advice.

    Green tea is the best choice for office workers. Why? Because green tea helps stop the bad result of the computer.
