At seven o'clock in the morning, the new clerk Zhou Ke came to the factory early because today was the day to hold the meeting.

At seven o'clock in the morning, the new clerk, Zhou Ke, arrived at the factory early. Because today was an important event to discuss cooperation projects with foreign businessmen and attract foreign investment, he had to rush to set up the venue before eight o'clock. Zhou Ke had already set up the venue before she got off work yesterday. Today, she needed to perfect some details. Zhou Ke wiped the oval-shaped conference table in the middle of the venue until it was spotless. Then, she placed a row of fruit plates on the conference table where the foreign representatives were seated and placed a sign of "VIP seats." Similarly, he also placed a row of fruit plates on the conference table in the factory representative's seating area and placed a sign that read "Factory Representative Seat", naturally dividing the venue into two parts. At eight o'clock, the representatives of both parties entered the venue punctually. Zhou Ke first politely invited Jack, the foreign representative, and his party to the "guest seat" and then arranged for "our own people" to sit opposite. He stood in a corner of the venue, ready to serve the meeting at any time. The negotiation went smoothly, but when it was about to end, the venue became very noisy. It turned out that the two sides had different opinions on the investment of funds. Jack thought that investing funds in a project that was not fully mature was risky and was an abuse of cooperation funds. The factory representative wanted to make it clear that they would never abuse the funds, because they had also repeatedly investigated, studied, analyzed, demonstrated, and conducted preliminary tests to finally decide on this project. The two sides argued and were in a deadlock. Zhou Ke's relieved heart started to worry again. At 10:30, the break time for the venue ended. The representatives of both sides walked out of the venue and took a short break. After a while, Zhou Ke saw Jack walk into the venue with his head lowered and sat on the factory representative seat. Before he could go over to remind her, she actually picked up the "fruit" in the fruit plate in front of her and was about to eat it. In an instant, Zhou Ke's heart was in her throat. She was dumbfounded as she watched Jack slowly put the "fruit" into his mouth... Zhou Ke was like a statue, completely frozen. Although the fruits in the fruit plates of the representatives 'seats and the special guests' seats were both "bright and juicy", the fruits in the special guests 'seats were filled with all kinds of fruits that were really fragrant, while the fruits in the fruit plates of the representatives' seats were colored and tasteless "fruit models". To put it bluntly, they were all kinds of "plastic fruits". Because it was done "exquisitely", it could almost pass off as genuine. Outsiders generally could not tell the authenticity, and only the factory employees knew this secret. Therefore, on such occasions, everyone had a tacit understanding that no one would touch the "fruit" in front of them. They would only watch the customers eat it. Today, he was also doing things as usual, but he never expected that something would go wrong on this. As expected, Jack frowned. He held the "fruit" that had already been placed in his mouth and looked at it repeatedly before looking around. When he saw the "Factory Representative Seat" sign on the conference table in front of him, he seemed to realize that he was sitting in the wrong seat. He looked at the 'fruits' in the fruit platter in front of him again, then got up and returned to his original seat. Zhou Ke's face was ashen. At this moment, the representatives who were resting walked into the venue one after another. When everyone was present, Jack stood up and solemnly said,"Everyone, I have signed the contract. I announce that we agree to cooperate with your factory and accept your proposal. We will transfer the first sum of cooperation funds to your factory's account in the near future according to the agreement of the contract." This sentence made everyone confused. Zhou Ke was also confused by this sudden change. Jack continued,"A factory that can be thrifty in every small detail will definitely not abuse every penny. Therefore, I have reason to believe that our cooperation will definitely be successful." Jack said as he pointed at the "fruit" in the fruit plate opposite him. The other foreign representatives were still confused. However, Zhou Ke and the factory representative reacted at this time. Immediately, there was a warm applause in the venue...
