There are many legends about the origin of oolong tea.
There are four possible sources: one is the theory of origin; The second is from tea varieties; Third, it comes from the name of the person who makes tea; Fourth, it comes from the shape and color of tea.
There is a story about a tea plantation owner who went to see instant tea and found an oolong there. He was so frightened that it took several days before he dared to come back to see it. Tea has been oxidized in the sun these days. It's not green tea anymore, but it's delicious and delicious. The shopkeeper called it oolong tea from now on.
It is also said that the earliest inventor of oolong tea is called Su Long (because he is black, it is called Oolong), so tea is named after people.
In fact, the name of oolong tea should still come from the form of tea. After drying, frying and baking, tea is black, like a fish (compared with a dragon). Soak in the water, the leaves are curled and bent, and the color is Qing Wu, like an oolong entering the water. Hence the name. Oolong tea, whether it comes from a place name or is named after a tea tree variety, is generally called oolong tea as long as the method is the same, including oolong tea varieties and other famous varieties, such as Tieguanyin and Dahongpao.
According to the textbook "Making Tea" compiled by national agricultural colleges, the origin of green tea (oolong tea) is that the working people in Anxi, Fujian Province invented green tea in the third to thirteenth year of Qing Yongzheng (1725- 1735), which was first introduced to northern Fujian and then to Taiwan Province Province. Tieguanyin, with its excellent quality and unique fragrance, has been copied from one place to another, spreading all over southern Fujian, northern Fujian, Guangdong, Taiwan Province Province and other oolong tea areas. At present, there are four major oolong tea producing areas in China, namely, southern Fujian, northern Fujian, Guangdong and Taiwan Province. Fujian has the longest production history, the largest output and the best quality, especially Anxi Tieguanyin and Wuyi Rock Tea.
What are the advantages and disadvantages of drinking oolong tea?
Oolong tea contains a lot of tea polyphenols, which can improve the function of lipolytic enzyme and reduce the cholesterol content in blood, and has the functions of lowering blood pressure, antioxidation, anti-aging and cancer prevention. If you are a person with a cold stomach, tea is not suitable for drinking more, enough is enough.
Who can't drink oolong tea?
There is no doubt that tea plays a role in human health, but it also has different requirements for different people, so people in poor health should drink tea carefully. It can be summarized as 3 1, as follows: 1. Avoid drinking tea if you have a fever. Caffeine in tea can not only raise the body temperature, but also reduce the efficacy. Patients with liver disease should avoid drinking tea. Most substances such as caffeine in tea are metabolized by the liver. If the liver is sick, drinking too much tea exceeds the metabolic capacity of the liver, which will damage the liver tissue. Beware of drinking tea because of neurasthenia. Caffeine in tea can excite the nerve center. Drinking strong tea for neurasthenia, especially in the afternoon and evening, will cause insomnia and aggravate the condition. You can drink tea once in the morning and once in the afternoon during the day. It is better to drink scented tea in the morning, green tea in the afternoon and no tea at night. In this way, patients will be refreshed during the day, calm and comfortable at night, and can fall asleep early. Pregnant women should avoid drinking tea, especially strong tea. Tea contains a lot of tea polyphenols, caffeine and so on. This has many unfavorable factors for the growth of the fetus in the mother's womb. In order to make the fetus develop normally and avoid the influence of too much caffeine on the fetus, pregnant women should drink less or not drink tea. 5. Women should not drink strong tea during lactation. Drinking strong tea during lactation, too much caffeine will enter the milk, and children will be indirectly excited after breastfeeding, which will easily lead to less sleep and more crying. 6. Patients with peptic ulcer should drink tea carefully. Tea is a gastric acid secreting agent. Drinking tea can increase the secretion of gastric acid and increase the amount of * * * on the ulcer surface. Drinking strong tea often will worsen the condition. But for mild patients, you can drink some light tea after taking the medicine for 2 hours. Adding sugar black tea and milk black tea is helpful to diminish inflammation and protect gastric mucosa, and also has certain curative effect on ulcer. Drinking tea can also block the synthesis of nitroso compounds in the body and prevent precancerous mutation. 7. Avoid drinking tea because of malnutrition. Tea has the function of decomposing fat. People who are already malnourished will be more malnourished if they drink tea to decompose fat. 8. Be careful when you are drunk. Tea has the function of exciting the nerve center, and drinking strong tea after drunkenness will increase the burden on the heart. Drinking tea will also accelerate diuresis, so that toxic aldehydes in alcohol will be discharged from the kidneys before decomposition, which is harmful to the kidneys and health. Therefore, for people with heart disease or poor function, don't drink tea, especially don't drink a lot of strong tea; For healthy people, you can drink a small amount of strong tea. When you wake up, you can eat a lot of fruit or sip vinegar to speed up human metabolism and relieve drunkenness. 9. Take medicine with tea with caution. There are many kinds of drugs with different properties. Can you drink tea and take medicine? You can't generalize. Tannin and theophylline in tea can change chemically with some drugs. Therefore, when taking hypnotic sedative drugs, iron-containing blood-enriching drugs, enzyme preparation drugs, protein and other drugs, tea polyphenols are easy to react with iron and precipitate, so it is not appropriate to use tea to give drugs, so as not to affect the curative effect. Some Chinese herbal medicines, such as Herba Ephedrae, Ramulus Uncariae cum Uncis, Rhizoma Coptidis, etc., should not be mixed with tea. It is generally believed that it is not advisable to drink tea within 2 hours after taking the medicine. When taking some vitamin drugs, tea has no effect on the efficacy, because tea polyphenols in tea can promote the accumulation and absorption of vitamin C in the human body. At the same time, tea itself contains a variety of vitamins. Tea itself also has the functions of excitement, diuresis, blood lipid reduction and blood sugar reduction, which can improve the efficacy of the human body and restore health. In addition, people often think that it is not appropriate to drink tea when taking tonic such as ginseng antler, which is also reasonable. 10. Anemia patients should avoid drinking tea. Tannic acid in tea can combine with iron to form insoluble final compounds, so that the body can not get enough iron source, so anemia patients should not drink tea. 1 1. Patients with urinary calculi should not drink tea. Urinary calculi are usually calcium oxalate stones. Because tea contains oxalic acid, it will form stones with calcium excreted in urine. Patients with urinary calculi will get worse if they drink a lot of tea. 12. Avoid drinking tea on an empty stomach. Drinking tea on an empty stomach will dilute gastric acid, inhibit the secretion of gastric juice, hinder digestion, and even cause palpitation, headache, stomach discomfort, dizziness, upset and other "drunken tea" phenomena, and affect the absorption of protein, and also cause gastritis. If "tea drunkenness" occurs, it can be alleviated by taking candy or drinking some sugar water. 13. Avoid drinking a lot of tea before and after meals. It is not advisable to drink tea for about 20 minutes before and after meals. If you drink tea, it will dilute the gastric juice and affect the digestion of food. Moreover, because tea contains oxalic acid, oxalic acid will react with iron and protein in food, which will affect the absorption of iron and protein by human body. 14. Avoid drinking tea before going to bed. It is best not to drink tea within 2 hours before going to bed. Drinking tea will make you excited. ......

What are the characteristics of oolong tea?
Oolong tea contains a lot of tea polyphenols, which can improve the function of lipolytic enzyme and reduce the cholesterol content in blood, and has the functions of lowering blood pressure, antioxidation, anti-aging and cancer prevention.
Oolong tea was originally one of the tea varieties. Generally speaking, oolong tea and packaged tea belong to semi-fermented tea.
Oolong tea is the earliest tea exported in Taiwan Province Province. First seen in 1869, John Dodd, a British businessman, sold it to new york under the trademark of Formosa Oolong Tea, which opened the door for Taiwan Province's tea export. Its production process originated from Wuyi, Fujian, China, and it is a semi-fermented tea. At present, all semi-fermented teas in Chinese mainland are called oolong tea. Before 1970s, Taiwan Province Commodity Inspection Bureau only listed highly fermented champagne oolong, Bai Hao oolong or Fanzhuang oolong as oolong tea items.
The name "Baozhong Tea" first appeared in 1872. At that time, Daocheng oolong tea was unsalable, and it was transported to Fujian for fumigation and processing to make Baozhong tea. There is a saying: the early tea packaging was lined with cotton paper inside and outside, wrapped in square Shuang Yi, and covered with the shop number and trademark of the merchant. The tea contained in it is semi-fermented, so the packaged tea is a semi-fermented tea. 1938- 1970, the Commodity Inspection Bureau of the Republic of China classified and inspected all light and moderate fermented teas (including straight Wenshan packaged tea, hemispherical frozen top oolong tea, Tieguanyin tea and scented tea).
The current "seed-wrapped tea" refers to the light fermented tea rolled into straight strips, which are produced in Wenshan tea area, peach, bamboo and seedling in the north.
"Oolong tea" represents the general name of all semi-fermented teas, and its producing areas are all over the middle and high altitude tea-producing areas in the province. Frozen top oolong, alpine oolong, etc. take the origin as the prefix, representing the spherical semi-fermented tea produced in this area (please note: its variety is not necessarily Qingxin oolong). At present, packaged tea in a broad sense also belongs to oolong tea (because good packaged tea should also be pure heart oolong). Among the existing varieties in Taiwan Province Province, Qingxin Oolong, Taicha 12, Taicha 15, Wuyi, Narcissus, Bergamot, Lan Zhi (Tainong10/) and Sijichun have better quality. Followed by Huang Xin Oolong, Taicha No.5, Qingxin Daban, Red Heart Dayou, Daye Oolong, Hong Xin Oolong and Hard Branch Red Heart. Here are a few brief introductions: Bai Hao Oolong Tea: commonly known as "Fengfeng Tea", is only produced in Taiwan Province Province in the world. The top grade has obvious honey flavor, ripe fruit fragrance and mellow taste. British tea tasters praised this kind of tea as "Oriental Beauty" or "Champagne Oolong" or "Fan Zhuang Oolong". Tea leaves are tender and tender, and those made in summer with a lot of white buds are the top grade. Tea is shaped like a flower and has five colors: red, yellow, white, black and green. Hsinchu Beipu, Emei, Miaoli Laotianliao and Wenshan tea areas are the main producing areas. Wenshan packaged tea: tight rope, naturally curled tip, connected branches and leaves, beautiful dark green color, tender leaves hidden in Phnom Penh; The water is dark green and bright, clarifying the bright and beautiful underwater light; The fragrance is elegant, floating but not greasy; The taste is smooth and active, and the throat is sweet and moist. These high-quality tables are the characteristics of Wenshan Baozhong Tea, and they are also its charming places, like a girl, lively, innocent and gentle. Frozen top oolong tea: The frozen top oolong tea in Lugu Township has always been famous. It was named "Frozen Roof" because residents living at the foot of the mountain had to go up and down the mountain in order to climb to the top of the mountain to farm, and because of the frequent rain, the road was slippery, and in order to move forward smoothly, they often blocked the soil on the road with their fingertips. Therefore, this mountain was named "Frozen Top Oolong Tea", which is the origin of this name. Tieguanyin: Tieguanyin was originally the name of tea tree variety. Because it is suitable for making oolong tea, its finished oolong tea is also called Tieguanyin. The so-called Tieguanyin tea is oolong tea made of Tieguanyin variety tea tree. High-quality Tieguanyin tea strips are curly, strong and thick, showing the head shape of a green-bellied dragonfly. Fresh and moist color, sandy green, bright red spots and frosty leaves are one of the important characteristics of high-quality Tieguanyin. Tieguanyin soup is golden in color, rich and clear, with thick and bright leaves and silky luster. The brewed tea soup is mellow and sweet, and the entrance is sweet and honey-flavored; The fragrance is rich and lasting, and it has the reputation of "seven bubbles and many fragrances".

2. Tea and mutton
Although eating mutton from time to time is good for health, when eating mutton and drinking tea, the rich protein in mutton can "marry" with tannic acid in tea, producing a substance called tannic acid protein. This substance has a certain astringent effect on the intestine, which can weaken the peristalsis of the intestine, reduce the moisture in the stool and easily cause constipation.
