"All the harsh living conditions in this video are set for program effects, please do not imitate."

In the small and confined space, Dou Sheng sat on the floor.

"Hello everyone, today is a special plan, and the theme of the planning is poverty."

"The inspiration comes from a money-saving king. His monthly living expenses cost only 300 yuan. Audiences, 300 yuan, how can this be achieved? So, I set my survival goal-"

The screen is black, three big words: one hundred and five.

The barrage instantly crushed a neat formation: pulling seedlings to encourage growth.

Xie Lan curled the corner of his mouth and gently pushed open Dou Sheng's door. The room was pitch black, and Dou Sheng was sleeping heavily in the quilt. He turned on the computer and put on Dou Sheng's headphones to continue watching.

19682 people are watching, good guy.

Dou Sheng rang out in a lazy voice, "Ah, when I set up this flag, I actually went through some rough calculations. Students' money, clothing, food, business, and learning, just these four yuan, I think I can do it. As it turns out, in the first week, I did perfectly fulfill my plan."

In the picture, Dou Sheng was walking on the bridge wearing an old T-shirt and obviously disfitted pants. The wind was blowing his hair and flying in all directions. The screen showed the countdown and dynamic distance of class. He was planning the meal for the next week while walking.

"There are two vegetable markets near the school. After a week of practical training, I mastered some small rules. The east side is suitable for going after 10 o'clock, and the last toast costs one dollar and one large bag of expired and undeteriorated yogurt. The west side is suitable for going after 8 o'clock, and the edges are one piece of meat on the five-day bag. If you are lucky, you can still get the tip of the chicken wings. The main difficulty is that you can't grab it."

The camera flashed and the style suddenly changed.

The vegetable market was crowded with people, and the discount area was crowded with aunts and uncles. Dou Sheng danced with him and held the camera high above his head to protect him.

"Young man, what are you fighting with us!" A panting female voice came from the camera.

His vision shook violently, and Dou Sheng said, "I'm poor, I'm hungry."

"If you are poor, you can't eat these even if you are hungry. If you don't eat them for a long time!" The aunt said as she turned around accidentally, paused, and her eyes slowly moved up.

GoPro swayed from side to side and greeted him mischievously.

But her attention was obviously not on the camera, but looked at Dou Sheng behind the camera. It was not until another aunt squeezed past her that she suddenly came back to her senses, and suddenly plunged into the crowd, shouting: "How many packs do you want?"

Dou Sheng immediately became clever: "Just pack!"

"I'll pick the package for you. Go and grab the rapeseed over there. There are still five minutes left!"

Before he finished speaking, the camera had already made a sharp turn and quickly moved toward the other side.

-This is an alliance?

-Damn it so much that I laughed

-What kind of meat can you buy with this little money?

-The fat you don't want to cut your flesh, you can make you lose some weight, and there are also broken chicken pieces that you can't sell when you are due, but in fact they are quite a lot of money.

-Good guy, little rape, I remember beans don't like dark green vegetables

-So do you think he still chooses it now?

After a battle, Dou Sheng was panting and switched the camera forward. Someone scratched his neck, leaving two red marks.

The aunt came to meet him soon, and the two of them divided the spoils and bought a small bag of horned meat and a bag of wilted rapeseed one 9 yuan.

Dou Sheng said, "You put a piece of meat in five, and I put a piece of food in four cents, and I will give you one piece of food."

"Yeah, don't give it to the young man, I'll just rush to play with it." The aunt smiled gently at the camera, sorted out her sideburns and showed the gold bracelet on her wrist. "You add the aunt's WeChat, I have free discounts around this area."

Barrage:

-It turns out to be a rich woman, I feel respectful

- Look at it in a close eye

- Angel on earth

-The Bodhisattva in the World

Dou Sheng's voiceover was inserted into the video: "I felt very lucky at that time because this Aunt Wu did carry me and save a lot of money."

The screen switches to a WeChat group, the group name: Yangqianxiang Rich Group.

"After meeting her

I only realized that one dollar a pack of assorted leftovers is too luxurious. The correct solution is to join the group dish group in the community. Get up every morning to see which dishes have been reduced today. Through simple and crude economic principles, we learned that the price reduction of radish means that the supply of radish in the market that day is too high, and radish will also occupy a large proportion of the assorted leftovers bags of that day. So, why not just buy leftover radish?"

-Blind Student, you found the Huadian

-I would like to call him a genius

-The invention of economics is for you to buy vegetables

A huge spreadsheet appeared on the screen with the row coordinates being the product name, with detailed classification labels, the column coordinates being the date, and the dense numbers record the daily dynamic vegetable prices and rise and fall.

The second table is a dazzling mathematical modeling. A function button is inserted next to it. Click it to generate a daily vegetable price prediction.

Xie Lan was shocked by this watch and was stunned for a while before remembering that there were days when Dou Sheng did run to the information classroom every day.

-Science...Science and technology to cultivate immortality?

-I'm so laughing, what the hell is this?

- Although the God of Study is late, he is here

-He started He started

- After taking a screenshot, the first one is the time series, and the second one should be trying to use XGBOOST to predict several types of vegetable prices that do not have time fluctuations. Unfortunately, the data volume is small and the effect is poor. Professionals suggest that XGBOOST is not required to make this small model.

-What is XGBOOST?

-Is this something you, a high school student, should know?

"Ahem, let me state first. I made this watch with a school computer. Although my laptop is lying in the cabinet, in order to restore the authenticity of poverty, I still paid about thirty calories to consume. Yes, for poor people, calories, or physical strength, are also money."

The barrage didn't hear anything he said at all, and was worshiping the god of learning. The screen rolled over a wall of exam prayers.

"Until now, the three predictions of eggplant, beans and local eggs are still unclear, but the prices of other vegetables are already very accurate, at least they are very accurate in terms of whether they are rising or falling." Dou Sheng cleared his throat, "out of gratitude for Aunt Wu to throw bricks and attract jade, I shared this thing with her. But at this time, I didn't realize the seriousness of the matter."

The screen suddenly became dark.

The loud voice of Aunt Wu mixed in the noisy background sound of the vegetable market suddenly rang: "Doudou, Aunt Wu has been observing you for several days. She has a good brain, can manage the house, and is handsome. You don't study much, so why don't you consider coming to see the store for Aunt Wu? Aunt Wu's home is half a street in the service market. My three daughters are about to return to her hometown from another place, and it's still a good property for her own home."

The voice suddenly approached and whispered: "You show it well, my family can accept being in the back door."

Dou Sheng: "Hmm?"

-Damn!!!

-I'm dying of laughter today in this video

-Doudou, goddamn Doudou!

-Insert the door beans

-The aunt's child raising son-in-law

-You, OK, OK, show,

Human sadness and joy are not consistent.

Xie Lan frowned in a sea of ​​joy and clicked on the web to search for the meaning of inserting the door.

After a long time, he turned his head expressionlessly and glared at someone sleeping on the bed.

Damn, I never told him this boyfriend.

Annoyed, want to fight.

After the video, Dou Sheng returned to his calm tone: "Anyway, that's my last time to go to the vegetable market."

-23333

-Selling the body

-Forget it, you're not worthy

-After all, I still miss the second cat

-Don't adhere to male ethics

In the midst of laughter, the material was quickly interspersed with the actual challenges of these days. There was the canteen aunt who was stir-frying with the oil in the pot, the cup of "Chang'an" that the milk tea shop staff was used to add, Zhao Wenfeng's roar on the phone, the tin skin exposed after the toothpaste was torn apart, he lay in the public printing room of the school year, sat motionless under the shade of the tree, and muttered on Xie Lan's shoulder after school, "I'm so hungry."

Xie Lan came into the mirror and said with a clear voice

Leng, "Do you want to give up?"

"don't want."

"Then don't whine if you are hungry in the middle of the night."

"Don't hum, from today on, when you are hungry in the middle of the night, you will find something to eat."

“In place?”

"You are the only one who has to bed in the middle of the night."

The evening breeze on campus blows the sycamore trees, and the long camera pulls over the dancing flowers and leaves. Xie Lan's side face flashes by, and the picture is frozen on the high roof of the administrative building in the distance, with a peaceful night view.

-Is it my illusion? Lan Zai's neck is red

-And I was listening to him finish this sentence
