Tong Doudou took the drawings and walked around with Supervisor Liu, echoing in his head, fresh air holes, air conditioning holes, air supply outlets, and return air outlets.

She got into Su Sheng's car, still thinking about the central air conditioning pipeline.

Su Sheng glanced at Tong Doudou with his eyebrows, "Is there anything wrong with it?"

Tong Doudou shook his head gently, "I didn't figure out what Brother Liu meant by writing 19, 15.88, and 12.7 in the notebook." ”

"That's the diameter of the copper pipe, and the outside unit of the air conditioner is connected to the internal unit through copper pipes. Mr. Du's house is installed with a central air conditioner of one to ten, and the external unit is connected to a 22.2 copper pipe, and then divided into 19.05 and 15.88 with a divergent, and then continues to divide down. Depending on the P number of each machine, the diameter of the copper tube used will also be different. ”

Tong Doudou thought about "one support ten", from 22.2 to ten internal machines, how thin will the final copper pipe be?

Su Sheng saw that Tong Doudou was still confused, and smiled indifferently, "If you have time tomorrow, you can go to DZ Comfort House and let Sister Zhao from their store explain it to you systematically." ”

Tong Doudou blinked, "Then you can help me make a call, I don't know Sister Zhao, I'm embarrassed to go over rashly." ”

"Well, I'll call you. ”

Tong Doudou hurriedly said: "Thank you!"

"You're welcome. Su Sheng said slowly, "Actually, if you go to the comfort of your home to study, they can't ask for it." ”

Tong Doudou immediately understood what Su Sheng meant: "I'm just an assistant, and I can't help them sell goods." ”

After Tong Doudou finished speaking, he realized that he had more words.

Su Sheng smiled, "Selling goods is not necessarily a straightforward sales pitch, it can also be a matter of one sentence." The key is this sentence, how do you say it can get to the point and touch the hearts of customers. ”

Tong Doudou breathed a long sigh of relief and muttered: "I don't want to touch the hearts of customers, I just don't want to act like a fool on the construction site and don't understand anything." ”

"It doesn't hurt to learn a little more. ”

Su Sheng parked the car in front of the company, "I'll recommend the WeChat of the store manager of DZ Comfort Home to you, make an appointment with her before you go, so that she won't be in the store." ”

"Well, thank you. ”

"Don't thank me, if you can pick it up, you're helping me. Su Sheng wanted to get out of the car after speaking.

Tong Doudou hurriedly said: "Mr. Su, I want to know, why did you let me be an assistant?"

Su Sheng looked back at Tong Doudou, "I think you're suitable." ”

"Oh, I'll do my best not to disappoint you. ”

Su Sheng smiled: "May we have a happy cooperation!"

Tong Doudou pulled the corners of his mouth and smiled sweetly, "Happy cooperation!"

With a professional smile on her face, Shu Ting watched Tong Doudou and Su Sheng walk into the company, speculating in her mind what these two people were talking about in the car, and it took so long to get out of the car.

Tong Doudou returned to the office, put down her backpack, took a pack of tissues and walked to the bathroom, she felt that her face was covered with dust and needed to be cleaned thoroughly.

Aunt Cleaning was looking at her mobile phone, and when she saw Tong Doudou coming in, she hurriedly put away her mobile phone and asked happily, "Go to the toilet?"

Tong Doudou smiled: "I just came back from the construction site, wash my face." ”

The cleaner watched in surprise as Tong Doudou squeezed some washing liquid, and after washing his hands, he washed his face directly.

"You're just washing your face?"

Tong Doudou wiped his face with a tissue, "Well, I didn't prepare today, I'll bring a towel tomorrow." ”

The cleaner began to mutter, "You should use some hot water, can you wash your face like this?"

"I'm used to it, and I wash it at home. Tong Doudou said nonchalantly.

The cleaner continued: "You can't do this, you see Lin Na washing her face, the one used to wash her face, the one used to wipe her face, the one bottle on the left and the one on the right, you have to learn a little." ”

Tong Doudou smiled: "I'm too rough compared to them." ”

The cleaner came to Tong Doudou's side and said mysteriously: "You didn't look at Lin Na without makeup in the morning, I didn't recognize it." ”

Tong Doudou blinked, pretending to be puzzled.

The cleaner glanced at the door, "Lin Na looks very good, but in fact, those eyes and eyebrows are all fake." ”

Tong Doudou smiled, "Nana will dress up." ”

"You learn a little bit too. ”

Tong Doudou didn't want to talk to the cleaner anymore, she smiled, "I'll go back to the house and pack up my clothes." ”

"I'll pat it for you. The cleaner enthusiastically helped Tong Doudou pat the dust off his clothes.

Tong Doudou realized that the next time he went to the construction site, he needed to change his clothes.

In the past, she went to the construction site with Jiang Xue that had not started, and she felt that there was no dust, and if she had to go with the project in the future, life would not be so easy.

The cleaner also said, "You change your clothes next time, I'll wash it for you after you change it, and hang it in the hut where I put my tools after washing, and you can do it tomorrow." ”

Tong Doudou smiled but didn't answer, her brain began to transfer, and Aunt Cleaning had no reason to give her face like this.

After Tong Doudou thanked the cleaning, he returned to his office.

She picked up the glass and tried to drink it, but found it empty, but she didn't have the strength to catch it.

She lay on the table weakly, thinking in her mind why she didn't keep her mouth shut just now, and she had nothing to say to Su Sheng to tell the truth.

She glanced at the water cup again, and suddenly remembered that she was Mr. Su's assistant, and when she returned to the company just now, the first thing she did should be to pour water for Mr. Su.

If you have half of the initiative of the cleaning aunt, you should bring it up and help Mr. Su wash the overalls he wore just now.

At the thought of washing other people's clothes, Tong Doudou immediately dispelled this idea.

She breathed a sigh of relief and muttered to herself, "Let's deal with it." ”

There was a knock on the door, and Tong Doudou quickly sat up, "Please come in!"

Sister Gao, the warehouse manager, walked in with an electric kettle and a bag of paper cups.

"There were a lot of things yesterday, and I didn't have time to send it to you, you have nothing to cook some jujubes or ginger water in this kettle. You see what you still lack, I'll match you. ”

Tong Doudou was overjoyed when he saw the electric kettle, "Thank you so much, Sister Gao." ”

"Be polite to me, you sign the ledger. Sister Gao said, handing the account book to Tong Doudou.

Tong Doudou signed his name under the "recipient".

She said to Sister Gao: "Sister Gao, I heard Mr. Su say that the company has tooling. ”

"Yes. Sister Gao smiled, "That kind of work clothes, I'm afraid you will be too stumbling, so I am embarrassed to give it to you." ”

Tong Doudou has seen the camouflage overalls worn by those people in the engineering department, and he knows in his heart how ugly that thing is, but don't want it in vain.

She said: "The construction site is too dusty, so I just put on the dust." ”

"Then you can go with me to the storeroom and pick one up. ”

Tong Doudou locked the door, followed Sister Gao downstairs, and went to the basement warehouse to pick up things.

This time, Tong Doudou had experience, picked out overalls, gloves, and hard hats, and by the way, took a basin and two rags.

Wu Sha followed designer Hou Feng to come in from outside, she saw Tong Doudou holding a basin with overalls and a helmet in the basin, and asked with a smile: "Little girl, what are you doing here?"
