When Drinking Tea, one must pay attention to their physical condition. It's also advisable to avoid consuming harmful substances before Tea to prevent adverse interactions between the properties of food and tea, which could cause negative effects. One should also be mindful of their health status; if not well, it's best to refrain from drinking tea.

One: Do Not drink tea on an Empty Stomach or Too Cold or Hot Tea

Many people enjoy drinking tea, but it's important not to drink tea on an empty stomach as it can stimulate the stomach and lead to discomfort such as stomach pain. Additionally, one should avoid drinking excessively cold or hot tea. Cold tea can cause phlegm in the body and make one feel like they want to cough but cannot. Drinking very hot tea is also not recommended as it contains more stimulating substances that can affect the body, particularly for older individuals who may experience sleeplessness or headaches. The purpose of drinking tea is to cultivate one's mind and spirit and potentially extend life, but these taboos must be observed.

Two: Do Not Drink Tea That Has Been Steeped for Too Long

Tea that has been steeped for too long should not be consumed as the substances within can undergo auto-oxidation, which not only deteriorates the taste but also diminishes its value. Persistent consumption of over-steeped tea can lead to uncomfortable physical symptoms due to the high presence of microorganisms, making it unsanitary. This is particularly harmful for elderly individuals with weaker constitutions or immune systems, potentially shortening their lifespan. Additionally, one should not immediately drink tea after a meal, as it can interfere with the absorption of proteins, akin to ingesting poison.

Three: Do Not Drink Tea That Has Been Soaked for Too Long. Regardless of the type of tea, it is not suitable to let it steep for extended periods in water, whether it's Green Tea or floral tea. If tea steeps for too long in the infusion, its concentration becomes excessively high, and there are substances that do not easily dissolve in water. Drinking this can have adverse effects on health.

Four: Do Not Drink Overnight Tea. After brewing tea, it should be consumed immediately. If left for too long or overnight, it will breed bacteria and spoil, causing irritation to the digestive system and leading to gastrointestinal diseases upon consumption. Therefore, it is not recommended to drink overnight tea or tea that has been sitting for some time.

There are many considerations when drinking tea. One should avoid overly strong tea, tea that has steeped for too long, and tea that has been soaked for an extended period. Attention should be paid to the temperature of the tea when drinking it.
