There are all living beings in the world, how can it not be the ups and downs of tea" is not a question, this sentence is a rhetorical question.

The form of the question is to ask questions without doubt, asking questions and answering questions to guide readers to pay attention to and think about the problem; Depending on the needs of the content, the questions may be in the form of conjunctions. Some articles directly use questions as the title, which can attract readers, inspire readers to think, and better understand the central idea of the article; Some are used at the beginning or end of a paragraph or section of the article, which can play a transitional role in connecting the previous and the next. As for reasoning articles, in order to deepen the arguments, it is even more effective to set up questions and explain reasoning on key contents.

It's a rhetorical question, not an interrogative sentence.

Well, it has a deep meaning, it means the six realms of reincarnation suffering!

Life is like a pot of tea, this pot of tea is a world, life is like tea leaves in tea, ups and downs are inconclusive, but it will exude fragrance. Tea tasting can taste a colorful life, but also a different kind of life.

Those who are indifferent taste tea, do not seek fame and fortune, and just want to have a peace and tranquility. The frustrated person tastes tea, has seen through the red dust, and all thoughts are burned, just looking forward to spending the rest of his life silently.

Life is like a cup of tea, it is a little bitter when you first eat it, but you can feel sweet when you swallow it. A good cup of tea, to experience sun exposure, through screening experience, this process, there is no shortcut, no back door to break into, no smooth road to choose from, just like thousands of ordinary people who are working hard for their own lives, all glory must rely on their own fighting.

Life is like tea, you need to savor it:

Life is a process of climbing, at the beginning, the physical strength is enough, a little relaxed, close to the halfway up the mountain, the physical strength has been consumed half, the higher the road the more difficult it is to walk.

Maybe every step feels so difficult, bitter and tired, bitter, and painful, but every step forward, the sweetness of life will quietly increase a little more. Maybe you didn't realize it at the time, but many years later, looking back on the past, you will be glad that thanks to the bitterness at that time, you can accumulate the sweetness that is now there.

Life is like a pot of tea, a pot of tea is a world, people are like tea leaves, floating on the water when they are young, sinking to the bottom of the water when they are old, and releasing fragrance in the process of floating and sinking. The process of human life is to show their own value and meaning. Personal understanding, if there is any misunderstanding.

It is said that life is like a pot of tea, and a pot of tea is a world of people. Tea represents a person's experience, whether it is ups and downs, sadness or joy, it is full of memories, and it is very beautiful and evocative.

A person's experience, whether it is ups and downs, sorrow or joy, is full of memories, and it is very beautiful and evocative.

First of all, we know that tea is denser than water, and we can see that from the end result.

It's easy to understand that the tea leaves are floating on the surface of the water, but the water has surface tension, and the shape of the tea itself may also be like a boat to help it float on the water, and everyone knows that.

It's understandable that the tea is sinking because it's soaked in water, and it's lost the air and the protection of its own special shape, and when the tension on the surface of the water isn't strong enough to keep it floating, the tea sinks, and that's understandable.

Why does it go up after sinking? And that's where the hardest part of this question comes in, and we can actually think back to that time.

The ascent does exist, but but! It is important to note that not all teas will rise.

It's easy to figure it out, because the oxygen that dissolves in the water, and the little bubbles that some of the tea leaves have, and some of the tea leaves that sink with bubbles, go out as the temperature drops, and they stick to some of the tea leaves, and if you look at the tea leaves that go up, you can see that they all have some little bubbles on them.

It's these bubbles that carry them to the surface.

The last step is when the bubbles fall off and the tea leaves are finally transferred to the bottom of the water.

When making tea, why do some tea leaves sink and others float on it?

According to your idea, the density of tea after absorbing water is greater than that of water, so it sinks to the bottom.

There must have been air in the original tea leaves, and the air sank after being squeezed out by the water.

Water has a surface tension that supports tea leaves that don't enter the water (a lot of things you can put lightly on the water, but sink to the bottom as soon as you touch it or wait a while, that's the reason) so it doesn't sink immediately.

However, this equilibrium is very unstable, and the tea eventually sinks to the bottom due to gravity.

It's not so clear later.

Personal insights. During the roasting process of tea leaves, the water evaporates, and the specific gravity of the tea leaves is less than that of water, so it floats.

Words to continue

Tea absorbs more water, so the displacement increases, and when the buoyancy is greater than gravity, it floats ......

It is ...... when tea continues to absorb waterWhen gravity is greater than buoyancy....And he went down

After brewing, the tea buds are blooming, the leaf veins are green, like pieces of jade dancing, and the leaves are undercover, and the lips and teeth are fragrant, and the aftertaste is endless.

And every day, different tea brand stores open and old stores close, and the surface is calm, because this is a long-term gradual process, and many passers-by can't understand it.

In fact, it is not necessarily the case, the rise and fall of tea ** in recent years, from overnight fame to overnight wealth or short-term failure, has become a lot of people after dinner. Although the operation of tea ** and tea physical stores is very different, they are also the same, and they are also selling tea, but the methods and channels are different.

Tea shop owners are mainly divided into several categories, one is that they have a physical store or a part of the supply of tea, and they will put these sources on the Internet to sell, because it is just a personal behavior, a simple **processing, will be ** dried again, no time or do not pay attention to care, nor advertising, over time, naturally there is no business, it is natural to think that ** is a floating cloud or the like. In the physical tea franchise store, the same is true for some franchisees, the store is opened, not paying attention, just inviting one or two laymen to be responsible for watching the store, not doing promotion, especially for paid advertising, not paying first, how to get big sales and net profits?

The second category is that the tea is in full swing, and these shopkeepers have tasted the high volume, sales and profits brought by the high rent stalls in the network ** lots. The physical franchise part of the store naturally did not hesitate to grab the most prosperous ** store in the city in advance, hired a lot of money and even dug the wall foot of the peer, especially attached importance to the experienced tea shop management talents, and the corresponding marketing and management will also be impressive.

The third category, just the opposite of the third category, attaches more importance to the daily operation of tea than the first category, but does not spend a penny on advertising, many things are done by themselves, and employees are not invited, the boss does it all alone, in their opinion, the cost is the lowest, and the net profit is earned, and no matter how powerful the individual is, after all, he still can't fight a mediocre team, such shopkeepers, often choose cheap, free, do not consider paid, advertising does not do, such a master will also have a certain business, but after all, it is not big, and the income may not be as good as that of office workers. And to open a physical tea franchise store, if you do this, then it is a big problem, just imagine, cheap, small number of stalls, simple decoration, lack of packaging, lack of soldiers, no peripheral publicity, business can be so good?

At a great opportunity, a group of Chu Lan learned beef dishes to the cup I had just made tea, and the tea bamboo was floating and sinking. I felt compelled to explain this phenomenon. At the same time as I am going to talk about "reason" about "things", I want to use this example to try to cultivate students' ability to observe, analyze, and reason.

I said, "You have seen the phenomenon of tea floating and sinking just now, what else have you seen?" The classmates laughed.

No squeaks. I remade a few cups of tea and asked them to re-observe. This time they observed carefully, and then "chattered and discussed, summing up the results of the inspection

When the tea rises and sinks, the volume of the tea leaves increases chronically. The tea absorbs more and more water, and there are small bubbles on the tea leaves, which then gradually decrease. I affirmed their observations and asked:

Is the rise and fall of tea only related to the tea river itself? The students carefully observed and found that the theophylline leached from the tea leaves made the concentration of the lower part of the tea in the cup different, and the color of the tea at the bottom was lighter the higher it went. After affirming their observations, I reminded them not to limit their observations to the inside of the teacup, but to think

Is the reason for the ups and downs of tea only in the cup? Some of the students began to stay there, and some of the students were touching the cups, removing the cups, touching the table top where the cups had just been placed, and thinking about it. One of the students may have different heat transfer between the upper and lower parts of the cup when he washed the cup, resulting in different frustration in the upper and lower parts of the cup, but it is not certain just by touching it with his hands.

There is no variety of tea, if it is a dragon well in green tea, then use a glass cup when making tea, because it is necessary to ** the posture of the tea, the color of the tea soup, and you can see that the tea will be divided into two layers for a period of time, and the length of the tea is the same. However, green tea should not be brewed with boiling water, and boiling water is used for kung fu tea. If some tea leaves do not sink, most of them may not have reached the time, and there is also the tea leaves that are not moistened when brewing.

Tea leaves brewed with boiling water. Generally, the bottom of the leaf is delicate and multi-bud, and the buds and leaves are complete, soft, thick, and even; It is worse to be coarse and old, multi-tendon stem, thin tea, mixed, and broken tea.

Now I don't like to drink drinks very much, so I like to go to the tea world to feel that Zheng Jue, this tea world is indeed a place I like very much, at first I was not used to drinking tea, but then I liked the taste very much.
