However, this was easy to say but hard to do. How was he supposed to catch this murderer?

Jin Weiwei pondered silently in his heart about how he should catch this murderer.

Then, Jin Weiwei asked Tao Qi what the second floor's merchants did the most.

Tao Qi informed them one by one.

"Most of the merchants on the second floor sell meat. "Miss, since you want to raise some livestock to sell meat, there are more merchants selling meat on the second floor." Tao Qi told Jin Weiwei everything he knew.

Hearing that, Jin Weiwei did not express anything, nor did he say anything, he only wanted Tao Qi to accompany him for a walk.

Jin Weiwei walked amongst the merchants on the first floor. When the merchants on the first floor saw Jin Weiwei, they were all very enthusiastic and Jin Weiwei did not put on airs either. He was also chatting and laughing with them.

"Hey, Old Wang, I heard that business hasn't been doing well recently?" Jin Weiwei went to the merchant, Elder Wang, who was selling soybeans and tofu, and asked him about the recent business situation.

"Oh, it's Miss Weiwei," Old Wang said as he put down the things in his hands and led Jin Weiwei into the shop.

"Come, come. Miss Weiwei, take a seat. Servants, serve tea."

Jin Weiwei did not stand on ceremony as he walked into the shop and sat down.

"Why is Miss free to come today? Have you thought of another good idea to earn money? " Old Wang excitedly waited for Jin Weiwei to finish.

"No, why would I think of earning money the moment I see you? I have so much intelligence, I came here today to do some market research." Jin Weiwei told Old Wang her purpose for coming today.

"Market survey? This little one is stupid, may I ask Miss, what is this market survey about? " Old Wang looked puzzled. I wonder what Jin Weiwei means.

Actually, it was not only Old Wang who was confused, even Tao Qi who was behind Jin Weiwei had a face full of suspicion, as he did not understand what the market research was all about. She was like a baby waiting for Jin Weiwei's answer.

"I just want to investigate the business situation of each of your stores and see which items are being sold well and which ones are not doing well." Jin Weiwei explained slightly.

"So that's how it is. So what's the use of doing this market survey? " Tao Qi still did not understand, and asked directly. Old Wang had also been looking at Jin Weiwei, prepared to hear her answer.

Do you guys not understand? Just do this market research and you will soon know the situation of the customers in the near future. Think about it, buying things will take a lot of patience, in a certain era, it is unrealistic to contact them one by one. and then, based on this survey, come up with a product that fits. " Jin Weiwei was extremely thirsty, he then raised his teacup and drank his tea.

"What is this consumption tendency again?" Tao Qi this curious baby had another question.

Tens of thousands of horses were galloping in Jin Weiwei's heart, why is it that I still can't explain it clearly?

"Simply put, if your family's business is good, it means that the customer is satisfied with this store, so the number of times they come to buy is naturally many. On the other hand, the customer is more average with this store, so naturally they don't always come to buy things." Jin Weiwei tried his best to explain it using simple words. Finally, they understood what was meant by market research.

Jin Weiwei thought, wasn't I here to investigate a case? He didn't think that I would dig such a big pit for myself.

"I see, so that's how it is. Miss is really a girl, so it's like this!" Tao Qi's face was full of worship.

"Miss, the business here is not very good, does Miss have a way?" After listening to Jin Weiwei's long story, Old Wang spoke to Jin Weiwei anxiously, hoping that Jin Weiwei could change the predicament she was in.

"As for me, I don't have any good ideas, but Old Wang, you can try making some innovations. Look at these beans, tofu, they are all common knowledge. If I can give everyone a new feeling, I think it would have miraculous effects."

"Fresh vision, fresh vision …" Old Wang was deep in thought, and as he read these words, he did not notice that Jin Weiwei had already left.

Leaving the Old Wang's shop, Jin Weiwei walked around the first floor before arriving at the second floor, where he greeted the merchants.

What Jin Weiwei did not know was that from the moment she entered, she had been targeted by people, and upon seeing her exit Old Wang's shop, she went up to a shop on the second floor, took out a pen and paper, and quickly wrote down some words, then passed them over to an unremarkable attendant.

Although Jin Weiwei did not know if there were people watching him, but Jin Weiwei was betting that there were people watching her.

Jin Weiwei, who had arrived on the second floor, had the same thoughts as when she was on the first floor. Every household would discuss and chat, and without talking about anything useful, it was just some trivial matters.

After passing through all the shops on the second floor, she instructed Tao Qi who was behind her. He wanted Tao Qi to seal the entire shop and prevent anyone from leaving. After that, Tao Qi took away the box containing the proof. and brought everyone together.

I'm very sorry, but I will have to take up some of everyone's time here. I believe that everyone knows that my proof of the shop being framed is fake and I was forced to go to jail a while ago. It can be said that I was lucky that I got lucky. Jin Weiwei spoke slowly, and looked at everyone present as he spoke.

"Just now, I have roughly passed all the shops. Of course, I also did some other things during the market investigation. Everyone, don't worry, I didn't do anything harmful to you. After all, we are old neighbors. I believe everyone is also not willing to see me framed for no reason. They will definitely be willing to return my innocence."

"I believe in Miss's character. Young Miss can make me, Old Wang, do whatever you want, as long as it can help you. " Old Wang was the first to stand out and support Jin Weiwei.

With the support of the first person, many people started to support Jin Weiwei.

I have already found a way to change the proof of my shop. Here, I will still advise you to come out and explain yourself, but if you let me find out, then don't blame me for being heartless. I will give you one last night. Jin Weiwei said as he looked at the others.

"Alright, everyone can go back now. I hope that the killer can admit it by himself tonight. I have already ordered people to seal the shop, if you want to escape, you can try. I would like to thank everyone here for their support. "

Amongst the people, there was a person who looked nervous after hearing what Jin Weiwei said. His hands were clenched into fists and scattered along with the others.
