The fastidiousness of Chaozhou people in brewing Gongfu tea is worth learning from: the first brew is used to rinse the teaware, the tea is drunk immediately after brewing, and the tea leaves are replaced after three to four infusions. Discarding the first brew is equivalent to rinsing the tea. Drinking it fresh and changing the leaves frequently can reduce the amount of pesticides and other harmful substances dissolved in the water.

Office workers can choose a container with a strainer to separate the tea leaves from the tea water, preventing the leaves from being continuously soaked in the water, which increases the dissolution rate of harmful components. Before brewing, rinse the tea once with hot water. Rinsing with hot water is better than with cold water, and rinsing with cold water is better than not rinsing at all.

When dining out, try to avoid drinking the tea provided by restaurants, as the quality of these tea leaves is even less guaranteed. It's better to drink plain water or bring your own small packets of tea leaves.

Another potential issue with tea lies in the storage method. Improperly stored tea may spoil, leading to bacterial growth. Tea cakes are also prone to harboring bacteria, which may not be visible to the naked eye. The temperature of the tea water may not be sufficient to kill these bacteria. Drinking such tea can similarly affect health. Do not buy too much tea at once, and store tea in a well-ventilated area.
