In China, from emperors and princes, literati and ordinary people, tea is a blessing. People often say "seven things to open the door, rice, oil, salt, sauce and vinegar tea", and we can also see that tea has penetrated into people's lives in all walks of life.

Speaking of the origin of tea, people often quote "Shennong tasted a hundred herbs, met 72 poisons a day, and got tea (tea) to solve it". Legend has it that Shennong often goes to the deep mountains and forests to collect herbs in order to cure diseases. Not only did he have to walk a lot, but he also personally tried the collected herbs to understand and identify their functions. One day, he tasted a poisonous grass while picking herbs. He felt thirsty and dizzy, so he quickly found a tree to sit down and closed his eyes to rest. At this time, a gust of wind blew a few fragrant leaves. Shennong picked up two leaves and chewed them in his mouth. He doesn't want to taste the fragrance. He felt that his tongue was full of saliva and spirits, and the discomfort just now was swept away. After careful observation, he found that the leaf shape and veins of this leaf were different from those of ordinary trees, so he collected some and took them back for careful study, and later named them "tea". This legend implies that tea has medicinal functions when it was first discovered.

Shennong Herbal Classic recorded the efficacy of tea, which was the first pharmacological monograph written in China during the Spring and Autumn Period and the Warring States Period. Herbalists and medical scientists of all ages have regarded tea as a good medicine for disease prevention and health care. Medical Books, Hua Tuo's Food Theory and Tea Spectrum all record more than 20 functions of tea, such as quenching thirst, refreshing, promoting digestion, diuresis, relieving asthma, improving eyesight and intelligence, diminishing inflammation and detoxifying, and prolonging life. Chen Zangqi, a great medical scientist in the Tang Dynasty, even said in Herbal Supplement that "all kinds of medicines are medicines for all diseases and tea is medicines for all diseases", which almost deified the medicinal value of tea.

However, even if it is circulated as a beverage, the medicinal function of tea has not been annihilated. The prescription for treating tea is invented by Chinese medicine according to its efficacy and has a wide range of uses. With the intervention of modern medicine, related research has continuously confirmed the health care efficacy of tea. Because it has the health care functions of three antibodies (anti-swelling, anti-radiation, anti-oxidation) and three drops of blood (lowering blood fat, blood pressure and blood sugar), it is called "magical oriental leaves" by the west and is popular all over the world. The World Health Organization investigated the advantages and disadvantages of drinks in many countries, and finally concluded that "tea is the best drink for middle-aged and elderly people".

Laoshan tea has become the nectar drunk by Taoist priests because of its chestnut fragrance. It can be seen that the tea quality and taste of tea trees have a great relationship with the natural environment in which they grow. Super Laoshan black tea, the cords are very small, almost all of them are small buds. After brewing, the color is dark red and yellowish, and the taste is rich in fragrance. Super black tea has a unique taste, high aroma, strong taste and fragrant cheeks, which is different from black tea in other places.
