Drinking tea should be divided into seasons, and it is best to drink scented tea in spring, such as jasmine tea and Cynthia tea. Scented tea refreshes the mind and relieves spring sleep: drink green tea in summer. Green tea is the coldest of all teas. The coldness in tea is mild and it is hot in summer. Drinking white tea or black tea in autumn, such as oolong tea, Tieguanyin tea, Maojian tea and Yinhao tea, is moderate. You can get rid of summer heat in autumn and drink black tea in winter. Black tea has the function of warming the stomach, such as Lipton black tea and Qimen black tea.
