Chapter 65 How solid the foundation is now, how dazzling the future achievements will be!
At this stage, the foundation is still being laid.

Just like the fantasy novels I read in the previous life, the foundation is extremely solid, and then we can climb to the top in the future.

If you rashly learn those advanced knowledge, it seems glorious, and you will quickly become a scholar in the eyes of your classmates, but in fact you will lose your potential.

This kind of behavior pays off.

You have to eat one bite at a time, and you have to go step by step.

Don't get carried away just because you got the chance.

How solid the foundation is now, how dazzling the future achievements will be.

"Yu Hua, pay attention to safety on the road." Fang Yu stared at the smiling Yu Hua, pursed her lips, and said softly.

"Uh... I'll be careful." Yu Hua was stunned when he heard that, what danger could there be in the school, looked at Fang Yu, who showed concern in his eyes, but nodded and replied without saying anything unpleasant.

Nodding to Zhou Yuan next to him, Yu Hua left. Today, he became a master once, sowing the seeds of drafting standards. With the expectation that the two would grow into young shoots, he set foot on the road to the library.

Irregular teachers should be, and students who study hard should be even more.

Learning can't stop for a moment.

In the classroom, the two watched Yu Hua leave.

After Yu Hua walked away, Zhou Yuan retracted his gaze, glanced at Fang Yu who was beside him dazedly, and said softly, "Fang Yu, if you like Yu Hua, you should hurry up. The moment I changed my name, I knew he was different."

Yesterday afternoon, in the first class of arithmetic, Mr. Ren, Luo Wenguang, brought Yu Hua in, and then announced to the whole class that the new name would be changed from Birch of Birch to Hua of China.

The change of a word represents a different meaning.

Hello everyone, my name is Yu Hua, and Yu Hua's confident and solemn expression at that time still remains in Zhou Yuan's heart.

"I can't talk about liking, I just have some good feelings. Graduation is coming, it's too early." Hearing Zhou Yuan's words, Fang Yu fell into silence, his face was a little rosy, after two seconds, he took a deep breath and said.

The implication is very clear, she does have a good impression of Yu Hua, but she will never have a substantive relationship with Yu Hua before graduation.

"I'll go back first, remember, three principles." Zhou Yuan smiled and said nothing before leaving.

Fang Yu nodded: "I understand."

……

01:30 in the afternoon.

The weather is clear and the sky is clear.

Yu Hua had already arrived at the entrance of the library and was about to enter when suddenly, a voice came from behind.

"Student Yu Hua, classmate Yu Hua, please stay." This voice contained a hint of respect, it was a boy.

Fellow Daoist, please stay?

Hearing the shouting, Yu Hua stopped, and subconsciously flashed the sentence in his mind. He couldn't help laughing and turned his head. He saw a boy who was not tall, wearing round black-rimmed glasses, short hair, and a thin and frail figure. Very face.

Yu Hua looked at the introverted and unfamiliar classmate, greeted him politely, and smiled, "Hello, classmate, what's the matter?"

"Uh... Yu Hua, hello, I'm from the literature class, and I want to find you to buy an independent light bulb." Seeing the smile on Yu Hua's face, the thin boy relaxed a little, sorted out his thoughts, and said his own. Purpose.

When Yu Hua heard this, he was stunned for a moment. The polite smile on his face instantly turned into a sincere and genuine smile, and he greeted him: "Buy an independent light bulb? Of course, your classmate is your surname."

The buyer is at the door.

The buyer is at the door.

The buyer is at the door.

Say the important thing three times.

It's really good things and good fortune, the little rich woman Fang Yu bought three light source equipment, and took a class fee of 720 yuan yesterday, and today she ran into another door-to-door business.

Compared with Fang Yu, the rich lady in the class, Yu Hua is more concerned about this kind of real customer orders. Fang Yu is in the same class as himself, and in the eyes of others, it is inevitable to be suspected of childcare, but this classmate is different.

"My father taught me that if you don't say anything, you won't be expensive. My surname is Zhang, and I have a single name." The thin boy looked at Yu Hua and responded with a bow.

"Hello, classmate Zhang Wen, are you using it for yourself or the dormitory? Are you going to buy a few independent lamps? At present, independent electric lamps have not been officially sold to the public, but pre-orders can be accepted, and an independent electric lamp can last about three hours. I believe that you have also experienced the lighting in the past two days, and it only costs a dime to charge a charge, which is high quality and low price." Yu Hua introduced to Zhang Wen in a friendly and familiar tone without any sense of distance.

The surname Zhang is inevitably expensive. This is an etiquette and custom that has been handed down in the past. Yu Hua doesn't care much about it. Just like Zhang Fu, the manager of the Huangchenggen Bookstore before, people say that the surname Zhang is unnecessary, and he will not correct it.

Regarding the portable lighting sources, Yu Hua has not yet prepared for official sales in the past two days. After Fang Yu's three lighting equipments are installed and used, they will be ready for official sales.

However, the door-to-door business still has to be done.

"For the dormitory, for the dormitory, as long as one set is enough, Yu Hua, how much does this stand-alone lamp cost?" Zhang Wen, a classmate heard Yu Hua's series of questions, was a little dizzy, thought for a while, and responded.

After these two days of publicity and fermentation, although the popularity of portable lighting sources has come down, it has spread among the students. Students from the first class of science, and outside the dormitory are students from various literature classes.

Science classes and literature classes are bounded by doors.

The lighting effect provided by the 100-watt incandescent lamp has left a deep impression on many literature students, including room No. [-] where Zhang Wen is located.

Yu Hua, who was smiling, made an offer: "At least 60 per unit."

"60?! It's so expensive?" Zhang Wen, a classmate, was startled when he heard the quotation given by Yu Hua. He was a little surprised and surprised.

Looking at Zhang Wen, who was startled, Yu Hua was stunned for a moment, and finally felt relieved.

Finally, someone, like myself, felt that this thing was expensive.

Having been in contact with immortal classmates such as Liu Tao, Zhou Yuan, Ji Han, Tan Qing, and Fang Yu for a long time, Yu Hua has some doubts about money. During the Republic of China, the salary was very low, the remuneration was very low, and the prices were high, but this group of people just wanted to What to buy, nothing can send two imported chocolates.

There is really no comparison between this person.

Yu Hua thought that Peiping No. [-] Middle School was full of students with the ability to make money. Now, there are normal people.

Not easy.

It's really not easy.

"It's not expensive, it's really not expensive. You see, Zhang Wen, an independent electric light can be lit for three hours for only 80 cents per charge. For each head, it only costs 10 yuan for three years, the purchase cost is 60 yuan, and it only costs 17 yuan for eight people, how much is the total cost? [-] yuan and [-]."

Finally felt that someone was like me, Yu Hua came to the spirit, firstly talked about the cost of using independent electric lights, and then focused on the advantages of independent electric lights: "So what did you get? Three years of night lighting, bright lights, use High efficiency, not affected by daily power outages, 60 yuan is a one-time price, no additional fees are required in the future, if you place an order now, it will be installed and used next week. is the official version."

"It's not expensive after all... Wait, 60 yuan? Yu Hua, do you mean fiat currency?" Hearing Yu Hua's explanation, Zhang Wen nodded again and again. After two days of experience, the lighting effect of independent lamps Indeed, as Yu Hua said, the lights are bright, the use efficiency is high, and it is not affected by daily power outages. At the end, I was stunned and a little surprised.

"Of course it's fiat currency, what's wrong? Ocean can do it too." Yu Hua was a little confused.

"I thought you were talking about British pounds. I'm sorry. If it's 60 oceans, it's too cheap." Zhang Wen's face showed a trace of apology. He really misunderstood Yu Hua. I subconsciously thought it was sixty pounds.

Yu Hua's face is full of confusion: "???"

GBP?

The unit is in pounds sterling?

Gan!
Am I in international trade?

"I'm really sorry, classmate Yu Hua, there are already electric lights at home, but not in the school dormitory. Although it's cheap, you can only buy one. Otherwise, it's a waste of money. How much do you charge for the deposit?" Zhang Wen was embarrassed.

"..."

Looking at Zhang Wen with a sincere and apologetic face, Yu Hua almost spat out a mouthful of old blood. He took a deep breath and forced himself to regain his calm: "If you want to book, you can only pay the full amount. Is there a problem?"

Zhang Wen shook his head: "No, Yu Hua, do you charge pounds?"

"Accept, the ocean of pounds and dollars, as long as it is money." Yu Hua sighed.

"Okay, it's six pounds, and you don't need to make up for it. It's your hard work. I'm sorry, classmate Yu Hua." Zhang Wen heard this, nodded, took out a leather wallet from his arms, and took out a denomination from it. Five pounds of pounds and a pound note with a denomination of one, and handed them to Yu Hua.

In the current year, the exchange rate between sterling and fiat currency is about 1:10.1. However, because sterling is rare and precious, and much stronger than fiat currency, it rarely appears on the market, resulting in a real exchange rate generally around 1:10.5.

In other words, six pounds is equivalent to 63 yuan in fiat.

"Okay, I'll install the independent lights when they arrive." Yu Hua took the two white pound banknotes and glanced at them. They were full of English symbols and the bottom was white. According to the banknote identification map promoted by the National Government, carefully identify them. Check it out and confirm it's true.

Zhang Wen nodded and said, "Goodbye, Yu Hua."

"Goodbye." Yu Hua responded.

After completing his goal, Zhang Wen seemed very happy, and he walked briskly with a smile on his face when he left.

"It turns out that the person from a poor family is me." Glancing at Zhang Wen who was leaving, Yu Hua sighed softly and turned his eyes to the two pounds in his hand.

The sterling of this period is very interesting, mainly white sterling, characterized by only patterns, no shading, huge watermarks, and at first glance it gives a cheap feeling.

Well, Yu Hua took a closer look and made sure it was cheap.

Specifically, the cheap method is that the patterns and characters are all flat-printed. Except for the huge watermark, there is no anti-counterfeiting sign. There is a pattern on the front, and the back is completely pure white. Strong technology.

But it is undeniable that the six pounds in hand are real. Before the operation of Bernhard in Germany, the vast majority of sterling banknotes in the world were real.
