Chapter 138 The Passionate Twins "Who are you looking for, young man?" Zhou Yimin handed over a cigarette and said, "Uncle, is Lu Guofu and the projectionist in this yard?" "Are you looking for Guofu? He's from our yard, right in the front yard. You came at the right time, he's at home today." After the old man finished speaking, he shouted inside, "Guofu, come out, I'm looking for you." This is across the street, so it's normal that people don't know him, Zhou Yimin. In addition to the banquet for grandma's 60th birthday, Zhou Yimin also wanted to add some extra activities. Considering that grandma and her family like to watch movies, he found out the residence of one of the projectionists at the steel plant. There are three projectionists in their steel plant. Lu Guofu is the most experienced one. He has some relationship with Section Chief Wang and was recommended by Section Chief Wang. At this time, the door of the wing room on the left side of the front yard opened, and a middle-aged man walked out. It was Lu Guofu. In fact, the rooms on both sides can be called wing rooms. The room next to the gate of a courtyard house is called the back house, which was where servants lived in the past. Wing rooms, also known as dragon guards, refer to the houses on both sides of the main house, which are divided into east wing rooms and west wing rooms.

The east wing is located on the east side, facing west, and the west wing is located on the west side, facing east. The wing is lower in rank than the main house, and its size, materials, and decoration are slightly inferior to the main house. Generally, the elders live in the main house, and the younger ones live in the wing. In traditional dwellings, the east is the most respected, so the east wing is of higher rank than the west wing, and usually the eldest son and his wife live in the east wing. When Lu Guofu saw Zhou Yimin coming in, he naturally recognized him and hurriedly came forward to greet him warmly. Even if they had never seen Zhou Yimin, they had heard of him. Now the factory had added several new workshops, all because of Zhou Yimin's invention. "Hello, projectionist Lu! I am..." Zhou Yimin was sure that the person who greeted him with a smile must be Lu Guofu, so he prepared to introduce himself first. "I know, Comrade Zhou Yimin! I'm a friend of your Section Chief Wang, there's no need to be so formal. Come on, sit in my room for a while." In the steel plant, who wouldn’t want to make friends with Zhou Yimin? Zhou Yimin followed Lu Guofu and said as he walked, "Since you are familiar with our section chief, I will not be shy! Don't call me comrade, just call me Yimin. I will call you Uncle Lu?" When Lu Guofu heard this, he felt very happy and was eager to get closer to Zhou Yimin. He immediately smiled and said, "Okay! Then I will call you Yimin from now on. I can't guarantee anything else from now on, but as long as it involves showing movies, I promise to get it done for you." As they were talking, the two of them entered the house. There was another woman in the room, probably Lu Guofu's wife, and two young men, about the same age as Zhou Yimin, who looked similar, probably twins. Judging from their clothes, they were probably still studying. Immediately afterwards, Lu Guofu introduced his family to Zhou Yimin. Zhou Yimin was not wrong, the two young men were indeed twins. He was also surprised that the two young men actually knew him. After asking, he found out that they were his juniors. The school also knew about his invention of the water pressure well and solar cooker, and had promoted it a lot. It is understandable that if a school has a talented student, it must be publicized or shown off! The school also has Zhou Yimin's files, including photos, etc. Naturally, his younger classmates also got to know him. "Learn more from your senior brothers in the future, and don't be idle all day long..." Lu Guofu lectured his two sons again.

It was frustrating to think about it. The two sons were far inferior to Zhou Yimin. In fact, he did not have high expectations for his two sons. When they finished their studies, they would learn to project movies from him. As long as they learned the skills of projecting movies, he believed that his two sons would not starve. Projectionists are still very popular in this era. They went to the countryside to show movies, and in order to watch one more movie, the villagers would often give the projectionist some "local specialties", such as old hens, eggs, garlic, mushrooms, etc. Some widows would even secretly invite their projectionists to spend the night with them. Do you really think this is a secret? No one else in the village knows about it? They just don't want to get involved. A widow also has to support her family, so there should be a way for people to make a living in the village, right? Therefore, even if they know, the villagers usually turn a blind eye and pretend not to see it. However, there may be gossips who spread some unpleasant words behind the scenes. He didn't know what stimulated these two junior students in front of him, but they kept asking him about his invention. Judging from their appearance, they also seem to be very interested in inventions. "Brother, what do you think we should invent?" Lu Xuezhen asked passionately. Zhou Yimin: “…” Lu Guofu laughed and scolded: "Can you invent airplanes and cannons?" Asking such a question is simply stupid! You should think about what you can invent instead of considering what is better to invent. That is not what you should consider. Zhou Yimin did not discourage the enthusiasm of the two juniors. He organized his words and said, "You can first consider inventing some small daily necessities. Don't underestimate those daily necessities. They are closely related to us ordinary people. For example, a box of matches is actually very simple. It is a fire-making tool that can generate ignition through friction, made based on the principle that friction generates heat between objects and using the chemical activity of strong oxidants and reductants. Before it was invented, was it inconvenient for us to make fire? Matches may seem insignificant, but they play a huge role in human society. " In the second half of the 1855th century, yellow phosphorus was mainly used as an ignition agent. Since yellow phosphorus is toxic, it was gradually replaced by phosphorus sulfide matches. Although the latter is non-toxic, it may spontaneously combust at any time and is very unsafe. In , the world's first match factory established in Sweden successfully developed safety matches, which were gradually adopted by countries around the world. Zhou Yimin was telling the two people not to aim too high and to instead research the daily necessities around them. "For example, the water pressure well and solar cooker I developed are just tools for drawing and boiling water," Zhou Yimin continued. When the brothers Lu Xuezhen and Lu Xueyi heard this, they felt that it seemed to be right. It was not necessary to invent something grand. "Take the pencil in your hand for example. In the past, pencils did not have eraser caps. Later, an American painter found that installing an eraser on the other end of the pencil greatly facilitated writing and corrections, so he invented this pencil with an eraser. Isn't it simple? It seems like even a child can do it. But do you know how much patent royalties this invention brought to the painter? " The curiosity of the Lu Xuezhen brothers was instantly aroused. "How many?" A pencil with an eraser cap, this really looks simple! They can do it too. "55 US dollars, converted into our money, is about a million dollars." When these words were spoken, even Lu Guofu's eyes widened. (End of this chapter)
