"Wow, I really feel it, when Dad built this house, they used to pull a little brick, and then they pulled it after they finished building, but they didn't pull it all over like now. Lin Dachao remembered that he built the house he lives in now when he was just a teenager, but at that time he didn't hire many workers, but the foundation was built, and several uncles and Lin's father built it by themselves.

"That's right, at that time, I had to earn money to buy bricks, unlike now, when the conditions are better!" Lin Guanghua also said with emotion, because people at that time were generally hard.

The house began to be built, and the courtyard of the Lin family naturally became lively, Lin Dalei liked this kind of liveliness, and every day he had to play around the workers who built the house, touching the shovels they shoveled sand, stepping on them, the yellow sand piled up on the ground, and sometimes picking up bricks to play, and the workers who built the house also liked this cute little boy.

"Da Leizi, how old are you?"

"Four years old. Lin Dalei was not afraid of life at all, and generously replied to ask his workers.

"Oh, are you going to kindergarten?" the workers teased him during their lunch break.

"Don't go to school, I don't want to go to kindergarten. Unexpectedly, Lin Dalei was a little angry when he heard about going to school, probably because he asked him to go to nursery school a few months ago, which caused him to contract hand, foot and mouth disease, so he was unhappy when he mentioned going to school.

"Ouch, why don't you go to kindergarten?" the worker looked at Lin Dalei's angry little appearance and felt cute, so he continued to ask.

"There is a sickness in the kindergarten, and I need to be injected. Lin Dalei said with some fear.

"Oh, I see, is this sand fun?" asked the worker again.

"Fun. Lin Dalei replied with a smile.

"Leizi, you're making trouble again. Lin Dachao, who had just returned home, said when he saw his son who was playing with yellow sand.

"No troublemaker, your son is very smart. The worker looked at Lin Dachao and said with a smile.

"Hehe, I'm afraid he'll make trouble. Da Lei, come home to wash your hands, wash your face, it's time to take a nap for a while, and you can grow taller when you sleep. Lin Dachao coaxed Lin Dalei home. Lin Dalei followed Lin Dachao home.

"Mom, you'll watch Da Lei sleep for a while, I'm going to go out. After helping Lin Dalei clean up, Lin Dachao took Lin Dalei to Zeng Shuhua's room.

"Oh, okay, go take out the trash?" Zeng Shuhua asked.

"No, I'm going to the city today to attend a lecture by volunteers. Lin Dachao said with a smile.

"Yo, go to the city. Zeng Shuhua said with a smile, meaning that it would be very late to come back.

"Well, I signed up for the volunteer team in the city some time ago, and now they have a lecture on environmental protection and sent me an invitation, so I went to check it out. Lin Dachao explained.

"Well, go ahead. Zeng Shuhua felt embarrassed when she heard Lin Dachao's explanation.

Lin Dachao drove his car to the city and walked around the building where the lecture was held before finding a parking space.

"Hello comrade, please show your invitation. It took him a few minutes to find the door to the conference room, where there were two or three girls dressed as waitresses, all wearing orange volunteer jackets.

Hearing that the waiter wanted an invitation, Lin Dachao immediately took it out of her bag and showed it to the waiter, and she drew a tick in the corresponding place on the registration book and asked Lin Dachao to sign it.

"Come in, your seat is this. After he finished signing, another waiter gave him a seat number, and Lin Dachao took the seat number into the conference room.

There were already some people sitting inside, and Lin Dachao found his place according to the seat number and sat down, looking around.

"Comrade, are you here for the first time?" Lin Dachao was looking curiously, and a man of the same size next to him took the initiative to greet Lin Dachao.

"Yes, it's the first time you're here, what about you?" Lin Dachao replied.

"I've been here two or three times, and each time it's different. The man smiled back.

"Really, that seems to be a fun activity?" said Lin Dachao with interest.

"It's a good activity, what do you do? I'm in greening. The man chatted with Lin Dachao enthusiastically.

"I'm engaged in environmental sanitation, and the greening is good, and it can purify the environment. Lin Dachao said sincerely.

"Well, now the city is developing too fast, it is inevitable that there will be environmental problems, so greening is more important, see that you are also full of kindness, let's get to know each other, my name is Xiong Hai, what about you?" Xiong Hai introduced himself, wanting to get to know Lin Dachao further.

"Hello, my name is Lin Dachao, you can also call me Xiaolin. Lin Dachao also happily introduced himself.

"Okay, Xiaolin, it seems that we are also half of the same industry, are you doing it yourself, or are you working for the company?" Xiong Hai looked at Lin Dachao and asked.

"I contracted the cleaning project in the village by myself, so I guess I did it myself, but I still have to listen to the village. Lin Dachao said with a smile.

"That's not bad, I'm still working for the company, and I don't have the courage to do it myself. Xiong Hai also said with a smile.

"That's also very good, I haven't been contracting for a long time, and I used to work for a foreign trade company. ”

"Ladies and gentlemen, our lecture is about to begin, please turn your mobile phone ringtone to vibrate and keep the venue quiet. While they were chatting, the voice of the organizer appeared on the radio, and after a while, a neatly dressed middle-aged woman walked up to the podium, and the lecture officially began.

"Hello everyone, I am very happy for you to come to our lecture, today we are mainly talking about environmental protection work under the current economic development situation, I am today's keynote speaker Liu Mei......"

After hearing her introduce herself, everyone applauded and warmly welcomed.

"Yo, that's amazing, this Liu Mei is a well-known professor of renewable energy in the environmental protection industry, I once saw her in a magazine. Xiong Hai was excited to see the real Liu Mei.

"Really, it seems that I am so lonely that I don't know her very well. Lin Dachao said with some embarrassment.

"That's because you've only come into contact with this industry, and you'll know about her in the future, she put forward the idea of turning food waste into enzymes, and it's also being popularized in some community pears." Xiong Hai seems to know Liu Mei very well.

"Really? Let's listen carefully. Lin Dachao listened to Xiong Hai's introduction and listened with interest.

"Okay. Xiong Hai also closed his mouth and listened.

The whole lecture lasted for a total of an hour and a half, and Xiong Hai and Lin Dachao never left their seats, and they didn't stand up and stretch until it was over.

"The lecture is a good lecture, but it's a bit long, and it seems like I'm back to the big class in college. Lin Dachao left the field with everyone, and Xiong Hai followed him.

"yes, I feel like I'm taking classes at university. "Xionghai returned.
