Liu Fei and Huang Ligong's bickering has a long history. No way, who made her the sister of Huang Ligong's best friend. Huang Ligong knew Liu Ruiyang when he was wearing open crotch pants, and naturally he knew Liu Fei - at that time, she was still called Liu Guihua, but when she grew up, she didn't love this name, so she changed it to Liu Fei.

Liu Guihua likes to follow behind her brother's buttocks, which is a sticky plaster. As soon as she stuck to her, Liu Ruiyang quickly sneaked out and took refuge in Huang Ligong. The two little boys didn't like to take Liu Guihua with them, there was no way, and it was the age when they were bored and disgusted with the little girl, so they changed their tricks, drilled under the bed, hid in the cabinet, climbed over the wall, threw off the dog skin plaster, and slipped out onto the street.

Wushan Town is said to be a small town, but at that time, it was actually a long street, born by the street, and slowly became a characteristic mechanical town. The street is north-south, and the signs along the road are hung with various factory names, which are basically related to auto parts. The two walked along the street, climbing trees, picking up discarded small parts and gadgets on the side of the road. Huang Ligong likes to play tricks, even if the scrap copper and iron are rotten, they can be combined into a new toy in his hands. He once teamed up with a rural carpenter brother to make an all-wood bicycle, except for the chain, frame, wheels, handlebars, and even the gears are made of solid wood. The carpenter's eldest brother won the county's skilled craftsman award, and that year, Huang Ligong was only in the fifth grade of primary school. It's a pity that there was no short video app at that time, otherwise he would have a good chance to become an Internet celebrity, the youngest handicraft expert on the whole network.

Liu Guihua's interest soon shifted to Huang Ligong. Strange, why does he like to tinker with these things, why does he have so many weird things in his brain? He will also stand on the top of the hill with one hand on his waist, commanding his friends to rush left and right, and stage a confrontation battle. In comparison, his own brother Liu Ruiyang is much more boring. Liu Ruiyang likes to be quiet, sitting on the bench, reading a book for an afternoon, or holding a complex machine, studying for hours, without moving his butt. At that time, they all lived in the power engine factory in Wushan Town, and turned right at the gate of the factory, which was the family courtyard. Liu Ruiyang has a table and a stool at the door of the dormitory building, sitting quietly to write homework and read books, which has become a scenery in the community. Naturally, since the first grade of primary school, Liu Ruiyang has been a top student on Wushan Long Street.

Liu Ruiyang also likes to fiddle with machinery, but unlike Huang Ligong, he always likes to ask why, and sometimes he will ask his father, who is an engineer. For example, why does a torque wrench make a "kata" sound? Liu Ruiyang fiddled and pondered, and finally figured out the doorway, so he ran out to find Huang Ligong to work, playing it seriously, but it was generated by its own internal torque release structure, and its structure is divided into three structures: pressure spring, torque release joint, and torque ejector rod. First, set the desired torque value on the torque wrench (the spring is placed on the ejector rod to apply pressure to the torque release joint), lock the torque wrench, and start tightening the bolt. When the bolt reaches the torque value (when the torque used is greater than the pressure of the spring), there is an instantaneous disconnection effect. At the moment of disconnection, the joint is struck, which is the "kata" sound emitted by the metal shell of the wrench.

In this regard, Zhang Wenfeng made a definitive conclusion about the coffin, it was a small dinner, the two drank and talked about heroes, talked about the mechanical spirit, Zhang Wenfeng said that Liu Ruiyang is the real mechanical madman. Huang Ligong was greatly dissatisfied, thinking that he skipped classes during college that year, and the fresh and interesting things he made out were endless, talking about theory, it was naturally Liu Ruiyang who put aside a few streets for him, but which madman was armed with theory.

Zhang Wenfeng said, you two are different, you are good at turning simple into complex, and Ruiyang is good at turning complexity into simple.

Huang Ligong thought about it, too, a few ordinary parts in his hands can always play an unexpected role and combine something new. And handed over the complex and incomprehensible things to Liu Ruiyang, and he quickly dismantled the most basic principles inside. Zhang Wenfeng asked him lightly, of course you are a mechanical maniac, making something out of nothing, and your creativity is unlimited. That's a mania. And Ruiyang has made complex things simpler, so that more people can create more awesome things out of nothing like you. Who's the more mechanical maniac, you say?

Huang Ligong was speechless and had to admit it, so he had to pick up his wine glass. At that time, he had not started a business, and Zhang Wenfeng wanted to persuade him to cheer up and make a career, so he changed his ways to stimulate and persuade him.

Huang Ligong and Liu Ruiyang became friends, and the Huang family's parents were overjoyed. However, every year is expected to be disappointed every year, even if there is a scholar who is a hardcore and soaks together every day, Huang Ligong seems to be inaccessible, and King Kong is not bad. The difference in the grades of the two, just like the personalities, is at one end of the spectrum. One is always at the top of the class, and the other is constantly moving within the bottom dozens. Until the second semester of the second semester of high school, Huang Ligong suddenly opened, all the way forward, more than half a year from the group of junior students, under the vigor, the college entrance examination was actually admitted to the province is not bad for a second book, studying mechanical engineering. His father cried with joy, his father praised him, Huang Ligong smiled and said nothing, he knew in his heart that the reversal of his life in the last year and a half of high school was not the coercion and temptation of his father, who was the factory director, nor the crying of his mother, but thanks to Liu Ruiyang. At the beginning of school one day in the second year of high school, without warning, Liu Ruiyang suddenly became more rigid than the head teacher, no matter how Huang Ligong protested, he always kept an eye on him, reviewed his homework together, did homework and papers together, and explained his mistakes to him before he was willing to let him go home. Huang Ligong was angry, his mind was too empty, he didn't do a single question, and Liu Ruiyang was not angry, when he did all the mistakes, he explained them one by one from the beginning. Huang Ligong thought that Liu Ruiyang would definitely not last long, he was wrong, he appreciated Liu Ruiyang's willpower for the first time, and after more than half a year, Liu Ruiyang was like this every day, Huang Ligong must cooperate seriously, and the two would play for a day on Sunday. Once you stick to it, it will be easier and easier to get a peek at the door. In the third year of high school, Huang Ligong no longer needed Liu Ruiyang to stare at him, so he worked hard and was admitted to university.

Liu Guihua did not have this kind of good luck. Having a scholar brother is more terrible than having a good friend of a scholar, and the legendary children of other people's families sit opposite him every day, and life has since entered the polar night. Parents always don't forget to nag themselves when they praise their brother, and they don't forget to praise their brother when they nag themselves. The more this is the case, the less Liu Guihua studies hard. After a few more words, she stiffened her neck, raised her eyebrows, and didn't reply, turning her head and snatching the door. Seeing Huang Ligong, he smiled and pestered him, wanting to follow him to watch the excitement. When she grew up, she couldn't easily get rid of it like when she was a child, Huang Ligong laughed at her for being a tomboy, and murdered her, wanting to cut off her thoughts and make plans for long-term stability. However, she is a tomboy but she is really tough, she does not show weakness, and she replaces defense with offense. She poured her grievances from her parents and brother onto Huang Ligong, sharp-toothed, laughing and scolding, but Huang Ligong couldn't resist it. The bickering became a meeting gift for the two of them, and they followed Huang Ligong throughout his high school career.

Huang Ligong and Liu Ruiyang went to college, and Liu Guihua's life seemed to have a large blank, and the shadow and noise disappeared at the same time. Without a reason to rebel and a wanton object, Liu Guihua behaved a lot, but unfortunately her studies did not grow at the same time, and finally enrolled in a marketing major in a higher vocational college. After graduating, the first thing she did was to change her name, a new name, a new life, and then rushed into the market, until she became the manager of the business sector in the "Understand Liquor" retail chain company, earned some money, and returned to her hometown in the town from time to time to visit.
