This is just a general idea. As far as I know, Chaoshan people like to drink Kung Fu tea, Tieguanyin tea, Narcissus tea, Pu 'er tea and so on. Lingnan people prefer to drink herbal tea. Herbal tea is a drink with the functions of clearing away heat and toxic materials, promoting fluid production and quenching thirst, which is developed and summarized by Lingnan people in the long-term process of disease prevention and health care, based on the local climate, soil and water characteristics, guided by the theory of TCM health preservation and based on Chinese herbal medicines.
