'Low air pressure' is a feeling of depression and depression, similar to the feeling of 'feeling unpleasant'. In a low-pressure environment, the partial pressure of oxygen in the inhaled air is lower than at normal pressure.

The partial pressure of oxygen in the alveolar air decreases, so that the pressure difference between the partial pressure of oxygen in the alveoli and the partial pressure of oxygen in the blood decreases, and the oxygen diffused into the capillary by the alveoli per unit time decreases.

As a result, the partial pressure of oxygen in the arteries decreases and the oxygen saturation decreases. This, in turn, causes the pressure difference between the oxygen in the blood and tissues to decrease, reducing the amount of oxygen diffused from the blood to the tissues.

Hypoxia occurs due to insufficient oxygen supply to tissues, coma can occur in patients with sudden severe hypoxia, and hypoxia and mountain sickness may occur in mild cases.

There is no oxygen, so stuffy.

Bai Ze looks like the outside again, today is really lively, this last customer has not yet come, another ...... One...... One......

In a daze, Bai Ze saw one after another Hades guests coming.

One hundred percent of the guests from the underworld had strange smiles.

This smile is the same as Xu Lei's.

With a sigh, Bai Ze welcomed the guest from the underworld in.

Pour it full of milk tea and listen to them.

recounts his sad past.

After listening to the stories, Bai Ze sighed, losing his former demeanor.

Black impermanence swallowed the boys and girls into their mouths.

"Brother, looking at your appearance, you don't want to die too, do you?" White impermanence comes in.

Bai Wuchang came in and saw Bai Ze, his brows furrowed.

Bai Ze glanced back and did not answer.

"Alright then, I'll tell you a story!" Bai Wuchang took out the milk tea he had never finished and took a sip.

Wolves and rabbits are neighbors. The wolf relies on his strength and often bullies the rabbit.

The rabbit has long wanted to "punish" the wolf, but he has never been able to find a chance.

One day, the rabbit found a jar of honey in the forest, and when he saw that he was not far from home, he encountered a pesky wolf.

"Hey, rabbit, what's in that jar?" The wolf glared at the rabbit and asked maliciously.

"Honey." The rabbit replied angrily. When the wolf heard that it was honey, his mouth watered, but he knew that the rabbit was very smart and difficult to deal with, so he deliberately asked again: "Is it really honey?" The rabbit said, "Who lied to you?" I'm never a liar. ”

The wolf asked again, "Is that stolen, or is it his own?" Of course it's my own!" The rabbit walked vigilantly as he spoke.

"Good! Good!" The wolf followed the rabbit with a smile, and thought to himself: It's not too late to grab it when I get home, and it saves me the effort to take the honey back! Thinking about it, it danced triumphantly.

After a while, they came to a crossroads, and happened to meet the lion, the king of the animal kingdom, who had fallen and was lying there resting.

The wolf hurriedly ran up and saluted, and said respectfully, "Dear king, I don't know that you were injured, please forgive me." ”

"Hmph, to put it lightly, I think you are dancing happily when you see that I am injured!" The wolf immediately said: "No, no! I dance because ...... Because ......" the wolf rolled his eyes and came up with a bad idea, he put his mouth close to the lion's ear, and whispered, "Actually, I have heard from others that you are sick, so I have been looking for a doctor for you."

I happened to meet a rabbit today, and I heard that rabbits can see a doctor, and they are quite skilled in medicine. So, I danced with joy." "Really?" The lion asked incredulously.

"Ouch, my king, do I dare to lie in front of my most respected king?" The wolf replied with an honest face.

The wolf's abacus is really bad! It speaks like this, and the lion does not blame it for dancing; Second, the lion can entangle the rabbit and take the opportunity to steal the honey himself.

The lion believed the wolf, and cried out, "Rabbit, I heard that you will see a doctor, come and see me!" The rabbit came up and said, "King, this is not a thing, who said I would see a doctor?"

The lion calmly said, "Wolf." When the rabbit heard this, he knew that it was the wolf who was mischievous, but it seemed that the king had already believed it, and it was impossible to refuse.

The clever rabbit had an idea, and he said to the lion, "King, I am really not a doctor, but my grandfather was a doctor, and I have learned a little from him, especially in the treatment of falls, and I really have a little experience." ”

"Then show me! Whatever you need, just tell me!"

"First of all, honey, I have a jar here, just for you; Then there is the skin of the wolf, which is good for plastering. ”

The rabbit said happily when he saw that the lion had believed his words.

The lion said boldly: "Easy to do! How much do you want?"

"Where do you hurt the most?"

"Okay, let's skin the wolf first." When the wolf heard this, he was so frightened that he broke out in a cold sweat, but he couldn't escape, so he gritted his teeth and endured the pain, so that the lion tore off a piece of skin from it.

The rabbit first smeared a little honey on the lion's and then put the wolf's skin on it.

Then he asked the lion, "Where does it hurt?" On the back, it seems to hurt a little bit on the back. ”

"Then I want another piece of skin from the wolf's back, right?" The lion tore a piece of skin from the wolf's back with another "whoosh".

The wolf couldn't stand the pain anymore, and cried and begged the rabbit, "Brother, spare me!" The rabbit asked the wolf, "Then will you still bully others in the future?" The wolf said bitterly: "Ouch, my life is almost gone, how dare I bully others!" Well, I'll spare you today!"

Then the rabbit smeared honey on the lion's back, put a wolf's skin on it, and then said to the lion, "O king, the wound has been bandaged, and the wolf has worked hard enough, let him go back to rest!"

The lion nodded and waved for the wolf to go back.

The wolf limped away. This bad guy, not only did he not grab the honey, but he almost lost his life! If you bully others, you will deceive yourself.

The clever rabbit "doctor" finally taught the wolf a profound lesson with his intelligence. When the rabbit came home, his teeth were laughing out.

Bai Wuchang frowned, this didn't react?

It seems that it has to continue, on a sunny Sunday, the little bird hummed happy music and came to Enping City, the hometown of Chinese hot springs.

When he first arrived in Enping, the bird saw a bare forest, and the streets were full of plastic bags, food bags, snow sticks, and melon seed shells...... Seeing that this place was so dirty, the little bird couldn't help but want to fly away, at this time.

Two people came in the distance, they looked at the bird, and couldn't wait to say, "Quick, catch the bird, make a delicious meal, and you can have a full meal." ”

When the bird heard this, he flapped his wings and flew away, but he was firmly stuck to the hateful chewing gum on the ground. The bird struggled anxiously......

"Wake up, kid!" A kind voice sounded in the bird's ear, "Grandma Monkey!"

It turned out to be a nightmare! The bird involuntarily sighed heavily.

It told Grandma Monkey everything in the nightmare just now, and Grandma Monkey gently stroked the bird's head, full of emotion: "I have lived here for decades, I have witnessed the progress of this city, yes, Enping more than ten years ago is indeed the same as in your dream, urban environmental sanitation and people's civilized spirit are indeed backward than now."

However, with the progress of the times and the improvement of people's quality, these phenomena have been improved, and the urban environment and people's spiritual outlook have undergone earth-shaking changes. ”

"Look!" The little bird looked in the direction pointed by the monkey grandmother, and saw that the streets were spacious and clean, and the grass was green; Cross streets, pedestrians and vehicles are in good order; A little girl in a red scarf was carefully helping an old man with gray hair to cross the street; In the island square.

A group of old people are playing Tai Chi in the corridor; Aofeng Mountain is full of flowers, thousands of purples and thousands of reds. What a beautiful city!

"You come with me!" Grandma Monkey and Little Bird got on the No. 8 bus together, and on the bus, everyone's faces were filled with warm smiles like spring.

I saw an old woman in her sixtieth birthday walk up to the car, and a young man hurriedly ran over and said, "Hello, grandmother! Come and sit here!"

The old grandmother said, "You are so good, young man!"

The young man waved his hand and said, "This is what I should do!" Seeing this, the little bird said happily: "I didn't expect that Enping has changed so much, and now everyone is polite, unlike before everyone sweared." ”

Grandma Monkey and Little Bird got out of the car and came to Fengru Square.

There are many high-rise buildings around here, full of flowers, birds and flowers, how beautiful!

I saw a little girl with braided hair who had just finished eating ice cream, holding an ice cream stick in her hand and asking, "Mom, where is the trash can?"

Her mother pointed to the trash can in the distance and took the little girl by the hand; At this time, a blank piece of paper floated out of nowhere, and the little girl immediately bent down to pick it up and threw it in the trash; A child is tired of playing and wants to sit on the grass and take a break.

But when I saw the wooden sign that said "Do not hurt the grass", I would rather go a little farther and sit on a stone chair in the distance. The little bird smiled and said, "What a beautiful, harmonious, and civilized Enping!"

Civilization has no length and no width, but it can be found everywhere. The "flower of civilization" has now bloomed all over Enping and all over the motherland! It was as if a beautiful song was ringing in my ears: the hot spring town is my home, and my home is like a painting......

Once upon a time, there was a royal palace, and a king was using his old hand to knock on the head of a man with few black hairs.

When the queen saw this, she asked unhappily with a big belly: "Your Majesty, what's wrong with you?" Did something happen? Don't you want children?"

"No, it's not!

My Queen!

It's just that last night I dreamed of a terrible witch who said, you will have a child until you are 17 years old, and you will be cursed by me.

Queen, if you say this is true, I'm really scared!" The king said in fear.

"Haha! Just by this...... Yes! It hurts, it hurts!!" Before she could finish speaking, the queen cried out in pain.

"Come on, the queen is going to give birth." The king called out quickly.

In this way, the queen gave birth to a cute and beautiful little princess!

The king said happily, "Just call her Vivien." The queen nodded in agreement.

Time flies, and in the blink of an eye, the beautiful Princess Vivien has grown up, and one day, 16 years later, the pale King mutters to himself, "What can I do!" What can I do......"

When Princess Vivien saw this, she asked, "My dear father, what is wrong with you?"

The king spoke of the terrible nightmare, and Princess Vivien listened and said, "Father, this is just a dream, don't worry so much. ”

"But it's your 17th birthday in a few days." The king said worriedly.

"Father, you don't have to be afraid! I'll take good care of myself, don't worry. Princess Vivien comforted.

Princess Vivien's 17th birthday arrived, and many counts and princes gathered at the banquet.

Suddenly, a black wind blew, and the black wind circled around the princess, and suddenly the princess turned into a beautiful bird on her head! I don't know who shouted: "The princess flew away!"

The king wept all day long, blinding his eyes because of the excessive number of tears, but his mouth still read: "My daughter! My daughter!"

After the bird flew away, she kept singing, and one day a prince on a white horse came to play.

When the bird saw the prince, he immediately flew to the palm of the prince's hand, and opened his mouth and said, "Prince, I am not a bird, but a princess, because I have been enchanted by a witch, and I have become like this, will you save me?"

As long as you climb Mount Ram and pluck the fruit of life for me to eat, you can save me, but there is a fierce giant on it, are you willing to go?" After speaking, the prince agreed without hesitation.

The prince rode to Mount Ram, climbed up the mountain, and without saying a word, drew his sword and stabbed it into the heart of the giant, and picked the fruit of life, and came to the foot of the big tree where he met the bird, and let the bird eat the fruit of life, and suddenly appeared in front of the prince a beautiful princess.

"Will you marry me?" The prince couldn't help but ask. The princess was impressed by the prince's sincerity and agreed with joy.

The prince immediately picked up the princess on his horse and took her back to her kingdom.

When they arrived at the palace, they saw a blind king. When Princess Vivien saw this, she immediately ran and began to cry, and just then, a miracle happened!

Princess Vivien's tears fell into the king's eyes, and in an instant, the king's eyes regained their sight, and the king said happily, "My daughter and this prince, in the future, will have a wedding!"

And just like that, the prince and princess lived happily ever after!

"Are you telling a bedtime story?" Bai Ze turned around in a daze, very sleepy, and his eyelids drooped.

"Eh, brother, if you are sleepy, go to sleep first!" Bai Wuchang patted Bai Ze's shoulder.

Bai Ze fell asleep grogily.

"It seems that it is the handiwork of the Yin Sect again, but this time there is the shadow of the world's unity." Bai Wuchang's face was embarrassed.

"It seems that the Yin Sect must be solved as soon as possible, otherwise Huaxia will ......be in danger," Lingyu frowned similarly.

Black Impermanence came back and looked at Bai Impermanence: "It seems that we have to look for it, this newly formed monster must be solved first."

"Well, unleash all the forces you can to stop the spread of the net." Bai Wuchang agreed.
