"Don't say it, Dr. Chen Linwei, you won't! You will definitely live a long life, and you still have to treat me and my grandmother, how can we do without you? ”

"Thank you for your good words!"

"Doctor Chen, this is not an auspicious word, it is a fact, you see that you are so good at understanding your heart, then your own problems will definitely be solved soon!"

"Looks like you're still enlightening me? All right! If that's all it takes, we can go together! ”

"Okay, I'm going to get a rabies vaccine now, I got bitten by a dog! It's a dirt dog, and I thought it was cute! I said as I followed Dr. Chan out the door.

The color outside is really bright, although this road leading to the place where the car just came in is like a crack, and there are small mounds of dirt next to it, but there is sunlight outside.

Anyway, it's better than the undecorated rough bungalow that Dr. Chen Linwei lives in, and now I understand why the house is decorated, not only to look comfortable, but also to be happy!

And people's mood will really affect people's behavior to some extent!

"When you think something is cute, it's your own kindness, and when it bites you, it means that its heart has changed, but you can't make your precious kindness disappear because of anyone's evil!"

"Dr. Chen, I understand, you told me this truth, and I read it in a book, which roughly means that a person saved a scorpion, but this scorpion bit this person instead, and as a result, this person will no longer be a scorpion in the future, until he dies, and he has to say to many people around him that he can't save the scorpion! But another person was stung by a scorpion, and next time he wanted to save some little lives, when others asked him, he said that although he would be hurt, this is nature, it has its evil, and you have your good! Don't change yourself because of anyone or anything! When the time goes on, you won't be able to tell if you're the biting scorpion! ”

"Looks like you read a lot! It is worthy of being the future pillar of the country! Do you know the probability of admission to your graduate school? ”

"Of course I know, it's 4%, we're the top talent, so we have to work harder! Dr. Chen, you must have graduated from a graduate school or a Ph.D. to study medicine, right? ”

The corners of Dr. Chen's mouth went up and he smiled slightly, "I'm an MD in brain surgery!" ”

Then, there was a star flare on his body, similar to the feeling of a star in the spotlight, projected onto his face, and he appeared shiny!

What makes him confident is not something from the outside world, but his own profession, because that's his pride!

"Sunshine doesn't always appear on sunny days, but also on cloudy days, as long as you can't see it with the naked eye. Just like a rainbow doesn't always appear after a rain, as long as you want to see it, it will take root in your heart! ”

"Dr. Chen, are you saying that you can see a rainbow on a sunny day?"

"Yes!"

Dr. Chan saw me on the side, and my head was raised at a 45-degree angle, and he must have guessed that I was fantasizing about a rainbow in my head.

So, Dr. Chan was telling me the story of the rainbow, and I listened with my eyes closed, as if the rainbow was really around me.

"Rainbows are caused by the dispersion and reflection of small droplets of water that are nearly circular when sunlight hits the sky. When sunlight hits a water droplet, it is incident at different angles at the same time, and it is reflected at different angles within the water droplet. The reflection at 40 to 42 degrees Celsius is the most intense, resulting in the rainbow we see. To cause this reflection, sunlight enters the water droplet, first refracts it once, then reflects off the back of the water droplet, and finally refracts it again when it leaves the droplet. Because water has a dispersive effect on light, the refractive index of light of different wavelengths is different, and the refractive angle of blue light is greater than that of red light. Since the light is reflected inside the water droplet, we see the spectrum upside down, with the red light at the top and the other colors at the bottom! ”

This Dr. Chen really knows a lot and talks more! If Dr. Chen changed his career to be a big brother who told stories before bedtime, he would probably be quite competent!

"In fact, as long as there are water droplets in the air and the sunlight is shining at a low angle behind us, it is possible to create a rainbow phenomenon that can be observed. Rainbows are most common in the afternoon, when the weather clears after the rain. At this time, the air is less dusty and full of small water droplets, and one side of the sky is darker because there are still rain clouds. When sunlight is visible without clouds above or behind us, the rainbow will be easier to see. ”

My consciousness is slowly fading, am I going to fall asleep like this?

"We can't see the rainbow when we face the sun, we can only see the rainbow with the sun on our backs, so the rainbow in the morning appears in the west, and the rainbow at dusk always appears in the east. But we can't see it, we can only see it when we look down from the sky by plane. The appearance of the rainbow is related to the change of the weather at that time, and we can generally infer from the position of the rainbow in the sky that there will be a sunny or rainy day at that time. When there is a rainbow in the east, it is not easy to rain locally, but when there is a rainbow in the west, there is a high possibility of local rain. In winter, the temperature is low, small water droplets are not easy to exist in the air, and there are few opportunities for showers, so there are generally no rainbows in winter. As the saying goes, the east color sun, the west color rain, which means that the rainbow in the east indicates that the next few days will be sunny, and the rainbow in the west indicates that it will follow, but it is not accurate, it is just a slip of the tongue. ”

Why didn't Dr. Chen speak, could he have suddenly disappeared? I was so insecure that I quietly opened my eyes in a half-dream, and saw Dr. Chan smile again and then look at me.

"Actually, rainbows can appear at any time."

Immediately after, he took a sip of water, and then sprayed water into the air on a sunny day, his lung capacity is really large, is it true that everyone who studies medicine is like this? I see that my grandmother's lung capacity is also very large, is this skill of theirs for artificial respiration of patients in an emergency?

At this time, a rainbow really appeared in the sky!

"I saw it, I saw it! It's so beautiful! Colorful! "I jumped and jumped with joy.

I squinted and straightened my hands forward, trying to reach the rainbow.

"Just take a sip of water? Dr. Chan, do you still have water? "I excitedly stretched my flickering little inner eyes into a big European style.

"Just one more bottle!" Dr. Chan pulled out another bottle of water from his bag and unscrewed it for me!

"Poof!"

Why not? No rainbows?

I took another big sip of water, "Poof! ”

Still no! Why can't I? Odd! I don't believe it today!

I took a sip of water, then breathed slowly, ready for 1, 2, 3, and go!

I'll wait a little longer, and I'll be lucky!

Dr. Chan thought that my mouth could start squirting water at the rate of the two times just now, but I was still preparing.

"If that doesn't work, use another sprayer! The point is to have small droplets of water in the air......"

I suddenly laughed, and a mouthful of water touched Dr. Chen's shoes, but it was okay, not on my face, otherwise it would be too disrespectful!

"Dr. Chen, I didn't know you were going to speak suddenly, what can I do? The shoes are all wet! ”

"It's okay! You've done a great job, but the droplets are too small. Because the size of the water droplets in the air determines the brightness and width of the rainbow. When the water droplets in the air are large, the rainbow is bright. It is also narrower. On the contrary, if the water droplets are small, the rainbow color will be lighter and wider, and the rainbow formed will not be obvious. In fact, rainbows are often seen near waterfalls. Splashing water or mist in the air with your back to the sun on a clear day can also create a rainbow! Dr. Chan took out the handkerchief in his bag and began to bend down to wipe his shoes.

Dr. Chan is wearing rainbow shoes? When I was a child, I dreamed of walking on the rainbow bridge, but when I grew up, I realized that it was impossible to achieve it, but it was a good idea to wear a rainbow on my feet, because walking this way is like stepping on a rainbow. It turns out that Dr. Chen is still a child, and he also has fantasies about the memories of his childhood, and he also likes the colors of the rainbow, it seems that the world of doctors is not only black and white, but their lives are also full of hope!

That's true, and who isn't?

The rainbow is really a personal thing that people love, but it is vulgar but gives people an invincible and beautiful image.

After polishing his shoes, Dr. Chan stood up and put the handkerchief in his bag, and I saw that the back of the handkerchief was also a rainbow.

Yes! Dr. Chan should always give himself positive energy like me, right? But he's better than me! Because he can carry a rainbow with him! I went back and wanted to make a rainbow cake, but forget it, it was too expensive. So make a rainbow rose, but that one is probably too troublesome to do, so it's better to buy a bouquet once in a while to add a little psychedelic to your life!

That's right! I should buy a rainbow umbrella with a wind, so even if it's cloudy, I can look up and see the rainbow!

"The nature class in primary school is probably the most interesting lesson I have ever had since I was a child, there are many experiments and a lot of common sense that you can use for a lifetime, and there are some methods that may be found in primary school textbooks. For example, fill a glass of water, put the cup on a table next to the window, be sure to have plenty of sunlight, place a piece of light-colored paper on the floor, wet the window with hot water, adjust the cup, and you can see the rainbow! And in a dark room, put a small mirror into a glass of water, take a flashlight to the cup, move it, and you can see the rainbow on the wall around it, in fact, these are just done in the room just now. The easiest way to go back is to look at the CD at the light and get a rainbow! There are also flashlights, but be careful to block out the light! ”

"I don't have a flashlight, but Shi Lanyan does, her flashlight should be a wilderness survival adventure, it's too bright, my thin hands can't cover up such a strong light. Besides, Dr. Chan, what age is it now, I don't have a CD, by the way, Dr. Chan, what year is it? ”

Dr. Chan took out his mobile phone, the kind with a dial.

Button phone?

I'm not going back to the way things were!
