Tian Yuming sniffed the smell of tea and said, "I heard that smelling the taste of tea leaves can also distinguish good tea." ”

Xu Jiuyan said: "The aroma of green tea also varies with the origin and type of tea, and the aroma of green tea is high and clear, pure and sharp. The aroma is low and turbid, dull and miscellaneous, or even has the smell of grass smoke and sour mold, which is inferior.

The smell also includes sweetness, intensity, turbidity, mellowness, astringency and bitterness, heat, and whether there is any deterioration of acid, rot, scorch, smoke, mildew and other bad smells. The taste of green tea, like the aroma, varies depending on the origin and type of tea. Roughly speaking, they are all sweet and clear, thick and mellow. Those with a weak taste, bitterness and irritation are not of the highest quality. Although some green tea is slightly bitter, it must also be bitter and sweet, and it has the smell of grass smoke, acid, and pythium. or those who are bitter and numb and pierce the throat are not of the highest grade. When identifying the taste, the entrance of the tea soup should not be too much, and the tea soup must be rotated from time to time in the mouth, so that the circumference can be reached on the tongue up and down, left and right, front and back. The tip of the tongue feels sweet and spicy, the tongue is sour on both sides, the root of the tongue is bitter, and the whole tongue feels salty. ”

"What about the color of the tea, the appearance?" Tian Yuming asked in detail.

Xu Jiuyan said patiently: "No matter what green tea, it is green and clear, and the water color is strong. Yellow turbidity and dullness, or free matter sediment, are not good. However, sometimes in order to meet the needs of consumers, the water color should be yellow but not green, and it is a different matter. When identifying the color of the water, it is necessary to tilt the cup slightly from time to time, and pay attention to whether there is any free matter.

Any green tea, the bottom of the leaf is turquoise, the leaf buds are delicate and even, the color is distinct, and the leaf is unfolded. The background color of the leaves is dark and sluggish, old and tender are different, cracked, curled, astringent and hairless, or mixed with green and black pieces, or there are irregular colors, dry but not moist and blistered, all of which are inferior.

The appearance of fresh green tea is bright green, shiny, and smells of strong tea fragrance; The color of the brewed tea soup is turquoise, with fragrance, orchid fragrance, cooked chestnut fragrance, etc., the taste is sweet and refreshing, and the bottom of the leaves is bright green.

The appearance of old green tea is yellow and dull, dull, and the aroma is low, such as blowing hot air on the tea leaves, the leaves are yellow and dry in wet places, and smell cold; The color of the brewed tea soup is dark yellow, the taste is mellow but not refreshing, and the bottom of the leaves is yellow and not bright.

The shape of spring tea buds and leaves is strong and full, dark green, moist, and the cords are tight and heavy; The brewed tea soup is strong, mellow and refreshing, with a strong aroma and a soft and bright leaf bottom. The shape of summer tea is coarse and loose, the color is mixed, and the leaf buds are woody; The brewed tea soup has an astringent taste, the bottom of the leaves is hard, the veins are exposed, and the leaves are mixed with copper-green leaves. ”

Tian Yuming was quite interested, and asked, "Then how can I judge whether it is good tea or bad tea?" ”

Xu Jiuyan put down the teacup, looked at the tea leaves in the tea bottle, and said: "What about the degraded tea, the mildew tea is sluggish, the tongue is bitter and heavy, the fragrance and taste are mildew, and it is not easy to unfold when soaked in water." Sour tea, the taste is thin, the aroma is low, the fragrance and taste are sour, and the bottom of the leaves is purple. The aroma and taste of the charred tea have a burnt taste, the bottom of the leaf is broken, and the bubbles are spotted, the taste is bitter and precipitate, the smoke tea smells of smoke, and the prickly throat of food makes people want to cough. The aged tea color is dry and not moist, there is stale gas, the water color is yellow and turbid, and it is not easy to unfold when soaking in water. Huilong tea is light and dull, and very light, chewing light and tasteless, and not bitter, and it unfolds very quickly when soaking in water. The aroma of fermented tea is not correct, the water color is yellow or red, and the bottom of the leaves is red. The fragrance and taste of the tea are rancid, the bottom of the leaves is purple, the color is dark and dull, and the water color is yellow and turbid.

When the price of tea is high, there are also unscrupulous people, mixed with holly, willow leaves, peach leaves, camellia, mountain green and other fake tea, or mixed with mud and sand and other impurities. The fake tea stalk is square and flat, the length is different, the cord is soft and hard, the color, shape, and fragrance are different, the soaking water unfolds slowly, the bottom of the leaf is narrow and long, the sawtooth is large and thick, the leaf vein is not raised, and it is broken by hand rubbing, dry and hairless. The tea of mud and sand, the color is gray and dull, let go of the hand and feel heavier, press it hard, there is the sound of sand and sand, the water color is turbid, the precipitation is very much, and the bottom of the leaves is rubbed like fine sand. ”

Tian Yuming suddenly smiled and asked, "Are you a student of Feng Yuan?" ”

Xu Jiuyan also smiled and said, "Yes, she is my high school biology teacher." ”

Tian Yuming stood up, took a photo album from the cabinet, opened it for Xu Jiuyan to see, and said, "Look, this was taken when I first met Feng Yuan." At that time, the first time I saw her, I felt that I liked her character so much, I really wanted to chase her, I asked her contact information everywhere, and I went to Nanyi City to find her whenever I had time, and I looked for her several times and then I didn't go. ”

"Why?" Xu Jiuyan asked.

Tian Yuming said: "Because she is married." ”

Xu Jiuyan smiled and said, "Then do you know who her husband is?" ”

"What I can't swallow the most is this breath, I haven't seen her husband's face now, this grievance!" Tian Yuming said leisurely.

Xu Jiuyan asked again: "Then do you know what Teacher Feng Yuan does?" ”

"Teacher Feng Yuan, Teacher Feng Yuan, of course a teacher!" Tian Yuming said naturally.

Xu Jiuyan laughed and said, "Then it's no wonder you can't catch up with others." ”

Tian Yuming asked with some doubts: "How do you know?" ”

Xu Jiuyan waved her hand and said, "You don't need to know this, anyway, Teacher Feng Yuan has also found true love, isn't it?" ”

Tian Yuming nodded and said, "You're right, so do you understand?" ”

Xu Jiuyan paused, then nodded and said, "I think I should understand a little." ”

"Tell me about it, I find that I seem to like listening to you." Tian Yuming said interestingly.

Xu Jiuyan smiled slightly and said: "I think I will handle the relationship between work and life, work should be done well, life should be good, not to be happy, just plain and sweet." As for this tea, as the old saying goes, life is like tea, and tea is like life. Life can be as mellow as good tea, some bad tea can be as bland as water, a good life can be as colorful as good tea, and a bad life can be as idle as bad tea. This is the same as investigating a case, if you want to solve the case, you have to pay the price, sacrifice time and energy, separate the good tea from the bad tea, and find what we are looking for. ”

Tian Yuming laughed and said, "Well said, life is like tea, tea is like life, it's so good." ”

Xu Jiuyan said: "Team Tian, I am not as proficient in criminal psychology as Guan Zheng, but I will try to do better. The 28th case is very difficult, but I will do my best. ”

"Of course I believe you, Guan Zheng's vision will not be wrong." Tian Yuming patted Xu Jiuyan's shoulder and said.
