Chapter 139 Asking for the Projectionist Nowadays, the RMB is still quite valuable, about yuan can be exchanged for 1 US dollar. Of course, you can’t buy dollars on the black market with yuan. As mentioned before, foreign exchange is extremely scarce in my country, and it is almost impossible to get some foreign currency through formal channels. Let me put it this way! If you use foreign currency to buy something, you don't need a ticket. This shows how important foreign exchange is. For this purpose, in 1960 and 1982, special tickets called "Overseas Remittance Coupons" were issued, which were only available to overseas Chinese and their families. These special tickets were issued by the state to encourage overseas Chinese to bring back foreign exchange to their relatives and friends in China. 凡是从境外带回外币折合人民币 100元的，可凭“侨汇券”增加供应粮食6公斤、食油1公斤、白糖2斤、鲜肉2斤、棉布10尺。 It can be said that foreign currencies are now similar to universal notes. There are many things that RMB cannot handle, but foreign currencies can. "This invention alone is worth 55 US dollars?" Lu Guofu was amazed. It's hard not to be shocked. More than one million RMB.

He couldn't imagine how much money that was. In this era, a family with an annual income of 10,000 yuan is considered wealthy in everyone's eyes. Zhou Yimin smiled and said: "The patent for this invention was bought out by the pencil company for $55, but the actual value is definitely more than that. It is impossible for a businessman to do business at a loss. Of course, in our country, we don’t talk about capitalism.” In fact, some inventions appear very simple and can be easily learned at first glance, with no technical content at all, but they are popular, consumed in large quantities, and therefore have high value. What Zhou Yimin knows is a product that is familiar to everyone. Post-it notes. Yes! Post-it notes are also an invention. Scientists were originally trying to develop a very sticky glue, but they found that they got a weak glue. Just when everyone was frustrated, 3M's Fulai discovered its true value from the experiment, and then Fulai obtained a business opportunity that could earn billions of dollars. It is said that when Post-it Notes were first produced, they were not successful in sales. Later, the marketers came up with the idea of ​​sending the Post-it Notes to secretaries of top 100 companies for trial. The response was very enthusiastic, and the Post-it Notes successfully created a good reputation and sold well. Until the 21st century, when Zhou Yimin traveled through time, Post-it Notes were still 3M's star product. The Post-it Note has not yet been invented and the patent has not yet been registered. In the past, the Post-it Note was invented in 1974. Zhou Yimin would definitely want to get a hold of such a product. Who can't do that? The key is just a weak glue. The two brothers Lu Xuezhen are talkative and they will talk non-stop whenever they catch Zhou Yimin. Lu Guofu knew that Zhou Yimin must have come this time to show the movie, and Wang Weimin had greeted him. So he had to interrupt his two sons. "Okay, go study first. We can talk about inventions later." After interrupting his son, Lu Guofu turned to Zhou Yimin and asked, "Yimin, are you here to show the movie this time?" Zhou Yimin nodded: "Yes, Friday is my grandmother's 60th birthday. She likes watching movies, so I want to invite Uncle Lu to Zhoujiazhuang to show two movies on Friday."

"There's no electricity in Zhoujiazhuang, right?" Lu Guofu asked. "No." "Okay! Then I'll bring the generator over as well." Lu Guofu secretly praised Zhou Yimin for being filial. In order to celebrate my grandmother's birthday, I specially invited a projectionist to show two movies. How many people can do this? Some people are not incapable and have the financial resources, but not many people do so. "Do you need my help?" Zhou Yimin asked. "If possible, it would be best if you could help me pull the generator over." Lu Guofu was not polite. The pile of stuff was really heavy, and it would be best if someone could help carry it! "No problem! Oh, by the way, here are some raisins given to me by a friend. Uncle Lu, please try them." Zhou Yimin then remembered what he had in his hand and handed it over. I bought the raisins for 1 yuan yesterday. "Oh? That's thoughtful. Raisins are not common!" As a projectionist, Lu Guofu considered himself to be knowledgeable and had come into contact with many good things, but raisins were indeed not often seen and were not necessarily available in fruit shops. "Wow! So much, Yimin, take some back." Lu Guofu took it and found that there were about 3 kilograms. This is too much. "Uncle Lu, I have more at home." After saying that, he said goodbye. He will pay you after the movie is over. Zhou Yimin also inquired about it. For example, hiring a chef like Master Quan to cook usually costs about 10 yuan, no more than yuan. Hiring a projectionist is a little more expensive, especially if he has to bring his own generator. Not to mention the wear and tear of the machine, burning oil also costs money, right? "Old Lu, these raisins are great, you should have some." Lu Guofu's wife ate two and praised. "Mom, let me eat something." Lu Guofu: “…” Are you eating a little? How much did you catch with that hand? While Lu Guofu was still in a daze, his other son reached out to grab a handful and filled his pocket, planning to take it to school tomorrow and let his classmates have a taste. On the one hand, it's showing off, and on the other hand, it's still showing off. Not only was he showing off the food, he was also showing off that he had met his senior Zhou Yimin and that they were very familiar with each other. They are looking forward to the envious expressions of their classmates. The twins are in sync and will run away when they get the advantage. Lu Guofu could only glare at his wife: "You did this on purpose, didn't you?"

He also caught a small handful, about twenty grains, and threw them into his mouth one by one, chewing them slowly. The taste was indeed good, sweet and sour, with a sweet side. "This kind of raisins should be quite expensive. Yimin is very thoughtful." Lu Guofu said to himself. "Such a promising young man, let Xue Zheng and Xue Yi spend more time with Yi Min in the future, maybe our Xue Zheng and Xue Yi can also..." said his wife. Lu Guofu rolled his eyes: "What else can you do? Invent? Don't think about those empty talkers, they are not cut out for it, and don't make it difficult for them. When they finish high school, they will learn to project movies from me, and at least they will have no problem supporting themselves in the future." Don’t you understand your own son? There is no such brain at all. Instead of expecting them to invent something, you might as well try harder at night and open a new account. Not pouring cold water on him just now was the last kindness he could show as a father. Mr. and Mrs. Lu Guofu didn't know yet that their two sons were now very passionate about inventions. After returning to their rooms, they began to think about various inventions. They adopted the advice of senior Zhou Yimin and started with the daily necessities around them. Because of this research (random thoughts), I neglected my studies, which resulted in a sharp drop in my grades. Zhou Yimin returned to his courtyard and met Li Youde. He casually mentioned his grandmother's 60th birthday: "You can go and help out then." "Sure! I'll go with Dapeng." (End of this chapter)
