After the New Year, it is the Spring Festival. On the night of Chinese New Year's Eve, Fang Wanshan did not keep the New Year, and he came out early in the morning of the first day of the new year to travel with his father, and when he met a neighbor he knew, he had to pay New Year's greetings and say auspicious words, all the business of the Fang family was closed on this day, and he had to wait until after the eighth day of the new year to start opening his business. Fang Wanshan didn't like these, so he basically stayed at home for a day, except for eating and worshipping his grandfather and going upstairs to the old house.

Early in the morning of the second day of junior high school, Fang's father and Fang's mother waited for the eldest brother-in-law to come over, and then led a large family to the second uncle's house in the New Territories. It was almost 11 o'clock when I got there, and the two aunts had already arrived, sitting in the field outside the house, and the kitchen was the eldest aunt, and the uncle and two cousins were helping. Mom's side is a big family.

The eldest uncle is 55 years old this year, has three sons and two daughters, the eldest uncle and the other 5 siblings are half-siblings, but the others are very close to him, the mother is closer to the uncle, and all the Fang Wanshan brothers are closer to the uncle. The eldest cousin and the second cousin are all married, and the third cousin is still studying, in a college, I remember that it should be graduating this year. The eldest cousin is a teacher and is married, but the uncle is more dissatisfied, because the son-in-law is very old and is also a teacher, but with a boy as old as the second sister Fang Jiao. The second cousin also got married, and married a carpenter nearby.

The eldest aunt is ranked second, how old it is, Fang Wanshan doesn't know much, only knows that his uncle's house is on the side, there are two daughters, a son, two cousins are older, the cousin is the same year as the second brother, and he will also take the exam this year, but his studies are much better than the second brother. There should be no big problem with passing. Fang Wanshan likes this second cousin the most, she looks a little bit beautiful, and the key is that she is still very quiet.

The second aunt is the third, one year older than the old mother, the uncle-in-law is a bricklayer, a son and a daughter, the daughter is about the same as the eldest sister, but she is not married yet, and the son is the same age as Fang Wanshan. When I was a child, the two brothers often took the four little ones from the second uncle's family to run around.

The second uncle is the fourth, Fang Wanshan generally calls him Uncle Bing, he has two sons and two daughters, the eldest is 1 year younger than Fang Wanshan. Fang Wanshan doesn't like this big cousin very much now anyway, he is very scheming and disobedient. Today, the second uncle went to his father-in-law's house over there, and the family turned out to be his grandfather's and left it to the second uncle, so he cooked at the second uncle's house today.

The third uncle is the youngest, he is not married, and he is not as big as the eldest cousin of the eldest uncle's family, Fang Wanshan is calling Uncle Wen.

After the Fang family came, several aunts took them to the grave of their grandparents on the mountain to pay respects, and when they came down, they began to play mahjong. After eating, they went home, and Fang Wanshan took the time to ask He Qiu, the second cousin of his aunt's family:

"What is Sister Qiu doing now?"

The second cousin, He Qiu, replied to him:

"I work in a factory. ”

Fang Wanshan asked his second cousin what factory it was, but it turned out that it was not the electronics factory that Fang Wanshan thought, but a small garment factory. Fang Wanshan asked the aunt's phone number and the second cousin's factory phone, saying that he needed the second cousin's help after the Chinese New Year. He Qiu is actually very envious of the changes in his aunt's family this year, but how old is the little cousin, what is there to help, it won't be to make clothes, and he didn't think much about it.

It's 4 o'clock when I got home, and my aunt's family has come over, my aunt is three years younger than Fang's father, my uncle is a professor at a polytechnic university, and he has two sons, and his life is still very good. Fang Wanshan had the impression that he was not too close to his aunt, and he went to his aunt's house once. In his aunt's house, "Fang Wanshan" felt more uncomfortable, and his aunt was very serious, sometimes it may not be his aunt who looked down on the Fang family, but there were still many differences in living habits and ways of speaking, so that Fang's father and Fang Wanshan, these juniors, were reluctant to get close.

Aunt Fang saw that her eldest brother and sister-in-law were back, and her grandmother also told her about the changes in the Fang family this year, and she was still very happy, but as soon as she spoke, Dad Fang was a little unhappy, mainly because of the second brother Fang Qiang's study, and some problems in the old house. Fang Wanshan actually felt nothing, he might not have experienced it personally, but Fang's father just didn't like this strong sister very much, but he didn't say anything, listen.

My uncle is a more temperamental scholar, and he does it quietly, while the second cousin seems to be very bored. Fang Wanshan was also not familiar with them, so he called someone and was about to go downstairs, but he didn't expect to be stopped by his aunt immediately:

"Wan Zai, I heard grandma say that you have made great progress this year, almost full marks, and my aunt is very happy. ”

Auntie turned around and bent down to touch Fang Wanshan's little face and said, "What do you want, tell your aunt, and aunt will buy it for you." ”

Fang Wanshan was actually very accustomed to being touched on his face, but he could only endure it, and said with a smile: "Auntie, I heard that my uncle teaches electronics, can you let my uncle teach me." ”

My uncle's name is Lu Gaohan, and I don't know how big Fang Wanshan is, hearing Fang Wanshan say this, Lu Gaohan looked at him curiously,

"Wan Zai, you want to learn from me now, but I teach physics. How about you learn the basics of middle school with your flying cousin first. ”

Fang Wanshan felt and said: "No, uncle, I saw the third sister with an electronic watch in the past few days, and I wanted to ask if you know how to do this." ”

Lu Gaohan couldn't help laughing: "You said this, this is actually very simple, you see that your third sister's electronic watch is actually made of quartz crystals." ”

After thinking about it, he said, "Generally, if a mechanical force is applied to the wafer, an electric field will be generated in the corresponding direction. This physical phenomenon is called the "piezoelectric effect". When an alternating current field is connected to the plates of a quartz wafer. Resonance occurs when the frequency of the applied alternating voltage is equal to the natural frequency of the quartz wafer. This phenomenon is called "piezoelectric resonance". This stable oscillation has created an electronic watch with extremely high accuracy."

Fang Wanshan's head was big when he heard the theory, so he immediately surrendered and said: "Uncle, I just look at this watch with a sense of science and technology, before the Chinese New Year, my eldest brother told me that I wanted to open a factory to make electronic watches, uncle, you are doing this, so I just asked you." ”

Fang Wanshan hurriedly pulled the eldest brother out to block the arrow, the family looked at Fang Wanshan with big eyes, Lu Gaohan didn't expect Fang Wanshan to answer like this, but he still said to the boss of the Fang family:

"Dafeng, my uncle knows this principle, but I have a friend who runs this electronics factory over there, and your cousin also learns this at school, so you two have a good chat. ”

Uncle Lu Gaohan said that Dushu's cousin is his eldest son, who is a sophomore at Polytechnic University this year and will graduate next year. There is also a son named Lu Fei.

The eldest brother Fang Wanfeng didn't expect his younger brother Fang Wanshan to give him this big pot at all, and he didn't know what was going on, so he had to nod hurriedly Okay, and his uncle didn't feel at ease to make money doing this, and his uncle replied directly:

"This thing is very simple, much cheaper than watches and mechanical, and it should be able to make money. ”

The family was relieved, and Lu Gaohan said again: "If you want to do it, you want to ask your cousin about this, and he should be able to help you." ”

Fang Wanshan hurriedly pulled the eldest brother to take his cousin Lu Shu downstairs, but the success of the electronic watch and other people paid attention, when they went downstairs, the second brother, sister-in-law, eldest sister and other juniors followed down.
