Good tea requires good water, and green tea is particularly demanding. Before mineral water and purified water were sold in stores, people in Beijing and Shanghai were not suited to drinking fine tea because the tap water in both cities was rather poor—Beijing's water is too hard, and Shanghai's has a strong bleach taste. Thus, the water used for brewing green tea is highly particular.

Green tea should not have a smoky flavor, yet Guapian's slight charred taste is somehow acceptable. In fact, the history of green tea in its modern sense is very short, with no real tradition to speak of, and ancient experiences are often incorrect. Nowadays, unless one holds a high official position, the Biluochun and Longjing tea they drink are mostly fake. Among the fakes, there are still good products; for ordinary people, drinking counterfeit green tea is as normal as watching pirated DVDs.

Drinking green tea should be as particular as drinking Kung Fu tea. In Suzhou, a double-layered glass cup with a perforated inner cup was seen; when drinking, the inner basket holding the tea leaves can be removed to prevent over-steeping. This is an excellent design, similar in principle to using two cups, especially suitable for brewing new tea. It is recommended that manufacturers produce more of these. We rarely get good tea, so making the most of it is essential—it's a shame not to enjoy it properly. Some people have plenty of good tea and take it for granted, often wasting it. Many people sitting on the podium prefer brewing green tea in thermos cups; seeing them drink it this way is heartbreaking for the tea leaves.

1. Lowering lipids and losing weight, preventing cardiovascular and cerebrovascular diseases: The relationship between tea drinking and weight loss is particularly close. The "Shennong Ben Cao Jing" mentioned the weight-loss effects of tea over two thousand years ago: "Long-term use calms the mind and boosts energy... lightens the body and prevents aging."

2. Detoxification and sterilization: Using tea as a detoxifying medicine, "Proceedings of the National Academy of Sciences" reported: "A chemical substance in tea named 'theanine' can enhance the body's ability to resist infection by five times."

3. Longevity: The anti-aging effects of green tea on the human body are mainly reflected in the coordination of several effective chemical components and various vitamins. Birth, aging, illness, and death are irresistible laws; so-called "immortality" is false, but "prolonging life" is real. Examples of tea drinkers living long lives are countless, both in ancient and modern times, in China and abroad.

The above is an introduction to the particularities of drinking green tea, hoping to help everyone understand this knowledge in daily life.
