In the small square of the Dongyue building materials market, there are some dark-skinned migrant workers squatting in twos and threes. Some of them looked left and right, and their eyes showed expectation. Some of them gathered together with cheap cigarettes in their mouths, muttering in their mouths, and their faces could not hide their anxious feelings.

These are migrant workers waiting for work.

Carrying heavy loads, laying bricks and pasting walls, cleaning and hygiene, as long as they can make money, they will not hesitate to sell their labor.

They are not afraid of hard work, they are most afraid of waiting for a day, but they have no work to do, no work means no income for a day, it means that the livelihood of the family cannot be maintained.

Lin Zeng parked the electric car on the side of the road, walked to the edge of the small square, and silently looked at the migrant workers on the edge of the small square.

About Lin Zeng's attention, attracting their attention, after a while, a middle-aged man in camouflage uniform, walked towards him.

"Little brother, do you want to find a job?" asked the middle-aged uncle with a Sichuan accent and a simple face.

"Well, find two people to build something. Lin Zeng didn't hide it, and said directly.

"What kind of work? Laying bricks, pasting cement, I am a good hand, if you want to put bricks, my nephew is good at it. Three hundred a day, you are satisfied. The middle-aged uncle's Mandarin was very awkward, and Lin Zeng sounded a little difficult, but he could finally understand what he meant.

"Three hundred, okay. Lin Zeng weighed it in his heart, and felt that it was not too expensive, Qinghe City is located in the southeast coast of China, with a developed economy, and the price and labor cost have always been very high. Besides, his construction is simple, and the workload can be completed in one day, so there is no need to worry about the gains and losses of dozens of yuan, "Master, your surname?"

"My surname is Zhang, hehe, little brother, wait, I'll call my nephew. After receiving the business, Master Zhang smiled happily, rubbed his hands and hurriedly said.

"By the way, I don't have any tools over there, only materials. Lin Zeng suddenly remembered and said.

"It's okay, it's okay. Master Zhang waved his hand, grinned and said, "We have all the tools, we bring our own." ”

"Okay, I'll wait for you over there. ”

Master Zhang trotted to the corner of the small square and said a few words to a young man.

Lin Zeng waited for a while, and then saw the two of them driving an electric car towards him. There are many tools hanging on the electric car of the two people, and it can be seen that these two people are relatively professional.

"Little brother, where are you going?" asked Master Zhang, stretching his neck.

"Here, go to Qingyixiao. Lin Zeng led the way, and the two followed, and in more than ten minutes, they arrived at the gate of Qingyi Primary School.

The security guard at the school gate saw that Lin Zeng had been in and out many times today, and he had already known him, and he did not stop him, and opened the door to let them enter the school.

Leading them to the office to be renovated, Lin Zeng pointed to the white line on the floor and explained the scope of the construction: "Lay bricks along this white line, the bricks stand horizontally, and after laying four high bricks, the surface is covered with tiles. ”

Master Zhang saw that there was not much work in his eyes, and there was some disappointment in his eyes, the more work they did, the longer they worked, and the more income they would get.

However, for Master Zhang, who has not found a job for three days, no matter how small the mosquito is, it is still meat, and in this off-season of decoration, he can work for a day and earn a day's money.

"It's a very fast job, I lay bricks by myself, and I can do it in one day, and my nephew waits for the cement to dry in two days, and then he will put the tiles. Master Zhang estimated the amount of work and said.

"Okay. Lin Zeng has no opinion. Give them the materials. Despite having only a small office, he tried indoor greening for the first time, and he wanted to do it perfectly.

Lin Zeng stood aside and watched Master Zhang's nephew expertly stir up cement and sand, thinking about his next move.

"Huh, what's the matter?" a clear female voice came into his ears, interrupting his train of thought.

Lin Zeng looked up, and on the edge of the dusty glass window, a girl with short hair pointed to the office with a confused expression and asked him. Her voice exudes a feeling of comfort,

"What's the matter?" Lin Zeng was a little stunned, blinked his eyes, and said subconsciously.

The girl walked to the door of the office, and Lin Zeng saw her appearance clearly. Her face looks a little boyish, but her eyes are extremely bright, her skin is fair, and she looks particularly fresh and moving in the summer with a simple pink T-shirt and powder blue jeans.

"Hello, where have the things in the office been moved?" the girl asked anxiously, "I put some things in this office before the holidays, and I don't know where they are now?"

Lin Zeng didn't know where he had gone.

Emptying the office was handled by the school, and when he arrived in the evening, it was already an empty room.

Lin Zeng explained the situation to her, and the girl rubbed her ears with some annoyance, "It's troublesome now, I'm going to go to the director of general affairs to ask about the situation." Thank you!"

Lin Zeng nodded and politely responded to the girl's thanks.

The girl thanked her and turned to leave.

She was probably a teacher at school, but she didn't look very old and didn't know which subject to teach.

Lin Zeng watched the girl's graceful back disappear at the top of the stairs, thinking a little distractedly.

――

――

After staying in the office for a while, Lin Zeng saw that Master Zhang and his nephew were methodical and skillful, mixed with cement and sand, and soon began to lay bricks according to his requirements.

Lin Zeng said hello to Master Zhang and left the office.

He still has an important task today, to understand the layout of Qingyi Elementary School in more detail. Find the most suitable location for three-dimensional greening. At the same time, we went to the site of the sky garden to improve the design plan on the spot.

If there is no accident, the greening project of Qingyi Sky Garden is the first project he embarks on. If you can open up the situation in this way, the following orders will definitely follow.

After all, the three-dimensional greening scheme he designed cannot be matched in the current Chinese city. In the city, the province, and even the whole country, becoming the first comprehensive three-dimensional green campus is something that any visionary principal cannot refuse.

The construction land of Qingyi Small Sky Garden is located on the roof of a teaching building in Qingyi Elementary School.

The school is located in the center of Qinghe City, where every inch of land is valuable, the surrounding land price is extremely expensive, the campus area is not large, and there are not many places for greening, so in order to improve the green area of the campus, we have to find another way.

Lin Zeng walked to the top floor of the teaching building to the east, but he didn't want to open the iron gate to the roof, which was guarded by the iron general and could not enter.

Lin Zeng had no choice but to check the situation on the roof of the teaching building through the iron door.

The floor of the roof is not flat, and the protruding pillars are the beams below. Other than that, there is only one water tower, which stands in the very middle. The safety fence of the roof is made of thick cement poured, about the height of an adult's chest.

Consider raising the fence with wire to create a safer space. Lin Zeng thought in his heart, and at the same time wrote down his ideas in the notebook he carried.

After checking the situation on the roof, Lin Zeng put his hand into the crack of the steel bar of the iron door, and took several photos with his mobile phone in different directions.

After looking at the construction land of the sky garden, Lin Zeng began to carefully inspect the campus environment of Qingyi Elementary School along the corridor of the teaching building.

As Lin Zeng expected, the regular green space on campus has been fully utilized.

However, Lin Zeng did not focus on those conventional places, but on the three-dimensional spaces that others could not green. Blank walls, hard concrete floors, classrooms, offices, and the ceilings of various function rooms are all places he pays attention to.

Write down the places you can play in a notebook and mark the plants that are suitable. As his feet traveled to all corners of the school, Lin Zeng's mind became more and more substantial.

If he is left to his devices, it will only take a few months, and the Qingyi small campus will become a real garden-style campus that will amaze the world.
