Because Zheng Dandan forgot to tell Tan Xueming the specific reporting time, Tan Xueming appeared at the Zheng family's door before dawn the next morning.

"Who are you and what are you doing standing at my door?" Zheng's brothers and sisters-in-law were about to go out to do business. The third brother Zheng Jianjun saw him, looked him up and down, and asked vigilantly.

"My name is Tan Xueming. Does Zheng Dandan live here?" Tan Xueming observed Zheng's brother and sister-in-law calmly and asked in a gentle tone.

Upon hearing this, the second brother Zheng Jiangong had a guess in his mind, "Are you my younger sister's new assistant?"

"Yes." Tan Xueming nodded and admitted.

After hearing this, He Yuegui and Fang Xiaoyu stared at Tan Xueming curiously. After hearing Zheng Dandan's introduction last night, they were all curious about Xiaomei's assistant!

"Wait a minute." After confirming Tan Xueming's identity, Zheng Jiangong returned to the room and came to Zheng Dandan. "Little sister, the assistant you hired is here."

"Now?" Zheng Dandan yawned and followed Zheng Jiangong out of the house in surprise. Because of the system in later times, she assumed that work would start at nine in the morning.

"Hello, am I not late?" After seeing Zheng Dandan coming over, Tan Xueming asked with a smile, expectantly and nervously.

"You came very early. From now on, you can leave by 8 o'clock in the morning." Zheng Dandan looked at Tan Xueming and asked with concern, "Is Niuniu feeling better?"

"Thanks to you, Niu Niu has been discharged from the hospital and should recover after taking the medicine." Tan Xueming said gratefully.

"That's good." Zheng Dandan nodded. She felt a sense of accomplishment in saving someone. "Since you're here, why don't you go out and do business with my third brother?"

"Okay, just give me your instructions directly. No need to be so polite." Tan Xueming smiled and said to Zheng Dandan.

"Well, the main reason I want you to go is to teach my third brother to be more flexible and tactful in doing things. He has too hot a temper, and I'm worried that he will suffer in the future." Zheng Dandan emphasized her request to prevent Tan Xueming from putting the cart before the horse.

"I understand. Don't worry." Tan Xueming responded, and at the right moment, he praised Zheng Jianjun again, "Your third brother is obviously a capable man. This man has his own temper."

Zheng Jianjun was listening at the side and felt a little embarrassed by the praise.

He was a little uncomfortable at first, but after getting Tan Xueming's approval, his resistance was instantly reduced by half.

"Don't worry, little sister. I will learn from you."

"Well, I wish you all the best, brothers and sisters-in-law." Zheng Dandan smiled. After seeing off the Zheng brothers and sisters-in-law, she went back to the house to take a nap. It was only past six o'clock.

Zheng Jianjun was responsible for selling oil and salt today, which were important and scarce items for the common people. Soon after the tricycle stopped, a large crowd gathered.

"Look, every time they come rushing over to grab something, I can't even hear what they're asking for. The only way to make things better is to yell at them. But my little sister won't let me be aggressive."

Zheng Jianjun was annoyed by the noisy crowd and complained to Tan Xueming.

He didn't want to be violent towards anyone, but if he didn't, the crowd would be undisciplined and noisy!

"Since you can't hear clearly, let's wait until they calm down." Tan Xueming glanced at the boiling crowd and said to Zheng Jianjun with a smile.

"Okay." Zheng Jianjun agreed without hesitation.

It was exactly what he wanted to do to prevent these noisy people who gave him a headache from buying anything. Besides, Zheng Dandan also asked him to study with Tan Xueming. Didn't she want him to listen to Tan Xueming?

So, the excited crowd soon discovered that no matter what they said, Tan Xueming and Zheng Jianjun ignored them and left them aside.

"What's wrong with you? Why are you ignoring me?"

"Are you guys in business?"

"Do you sell rapeseed oil and salt?"

The people who noticed the abnormality asked questions one after another, but even with all their talk, Tan Xueming still ignored them.

Gradually, the crowd's voices finally died down, and they looked at each other in confusion.

"I'm sorry, everyone. You were all talking about yourselves just now, and I couldn't hear a single word clearly. We are buying rapeseed oil and salt. Rapeseed oil is 80 cents per pound, and salt is 50 cents per bag." At this time, Tan Xueming spoke slowly.

"How could I not hear it?"

"That's right, my voice is so loud, how come you can't hear me?"

The people gathered began to express their opinions again, but this time there were obviously fewer people speaking than before.

Hearing the quarrel start again, Tan Xueming fell silent again and watched them coldly as they continued to express their opinions.

"Everyone, stop arguing!" Someone smart realized Tan Xueming's intention and shouted. They didn't want to buy anything, but I wanted to buy it myself.

The noisy crowd was instantly shocked when they heard this.

Seeing this, Tan Xueming slowly smiled.

"Everyone's voices are really loud, but everyone's talking. Who should I listen to? They're drowning out each other's voices. How can I tell the difference? So, I can only wait until everyone starts talking before I start selling. I'm really sorry."

"Then sell it to me first!"

"Why you? Why don't you sell it to me first?"

"I've been here a long time ago, you should sell it to me first!"

It is said that it is difficult to change one's nature, and it is difficult for people to change their habits. After knowing the reason, they quarreled again over the order of priority.

However, whenever they quarreled, Tan Xueming ignored them.

Without a response from Tan Xueming, their quarrel would be meaningless.

A few minutes later, the crowd quieted down again, and the people who had been arguing couldn't help but look at Tan Xueming with a guilty conscience.

Tan Xueming wasn't angry at all. "Everyone wants to buy things early, and I understand that. But no matter who I sell to first, the others will definitely be unhappy. So, how about everyone just queue up? It's been said since ancient times that first come, first served, this is the fairest way."

Most of the people gathered here actually don’t have the habit of queuing, but as Tan Xueming said, if they sell to others first, they will definitely be unhappy.

So they thought for a moment and quickly lined up in an orderly manner.

With a team, there is order. Whoever takes the turn speaks first, and there is no more trouble with multiple people talking at once.

"I want three pounds of rapeseed oil."

"I want five pounds of rapeseed oil and a bag of salt."

"I want five pounds of rapeseed oil."

"I want two packets of salt."

…

Zheng Jianjun and Tan Xueming worked together to sell goods, one collected the money and the other shipped the goods, and the speed was surprisingly fast.

Soon, the goods were sold out, and those who gathered first left with full bags. Although there were still people waiting in line, they had arrived later.

People have a herd mentality, no matter what the habits of those who come later are. They saw the long line and naturally lined up at the back.

“Why are they sold out? I waited in line for so long for nothing!” The customer at the front of the line said sadly as he watched the last bit of goods being sold out.
