Zhang Jing opened his mouth and said, "How do you say this? ”

Yang Tongtong replied: "Let's let my sister say it, she said it clearly." ”

Zhang Jing's eyes looked at Yang Xinxin, but Yang Xinxin did not refuse.

Yang Xinxin was an old actor as soon as she opened her mouth, and said: "Mom, you listen to my quibbles!" ”

The three of them and one cat are all puzzled, what is it called listening to my quibble, what do you want to quibble?

Yang Xinxin also knew that she had said the wrong thing, so she hurriedly defended: "Mother, you listen to my explanation, this is the case. ”

Then Yang Xinxin explained how he met and met the Rubik's Cube, and then the Rubik's Cube became Xiao Luomo, and how he and his brother decided to hide it from their parents.

To sum up, the appearance of aliens is too unbelievable.

If you tell your parents, not only will your parents be very surprised, but they may also send Xiao Luomo to the research institute and cut it into slices.

When the time comes, let alone Xiao Luomo going back to the planet he saved, maybe he will be cut into pieces by the Academy of Science.

Zhang Jing and Yang Xuewen listened to Yang Xinxin's quibble, no, explain, and suddenly felt so reasonable!

But in this matter, Zhang Jing still has to educate Yang Tongtong and Yang Xinxin.

Zhang Jing spoke: "Do you know where my mother is most angry? ”

Yang Tongtong and Yang Xinxin shook their heads, and quickly nodded again.

Yang Xuewen felt very funny next to him, and he was happy.

As soon as Zhang Jing's gaze came, Yang Xuewen's face immediately became serious.

Yang Xuewen opened his mouth and said, "Listen to your mother!" ”

Zhang Jing said: "The most angry thing about my mother is that you lied to your mother, the two of you, one is seven years old and the other is six years old, do you think it's good that you don't have a word of truth in your mouth?" Whatever the reason, I want you to be honest children, unless you are forced to tell white lies. I hope you will remember that if you tell a lie, you will use countless lies to fulfill that lie. ”

Yang Tongtong and Yang Xinxin nodded and whispered, "Okay, Mom, I know it's wrong." ”

In view of Yang Tongtong and Yang Xinxin's good attitude in admitting their mistakes, Zhang Jing also believes that after his persuasion and education, they will definitely not make such mistakes in the future.

So, I must forgive them!

Now that this matter is over, the family's first task is naturally to help Xiao Luomo, an alien cat, and save its own planet.

Whether it is the adults of this family or the children, they all know what the planet of Little Ink is going through now, and they also want to contribute to this distant planet.

At the dinner table, Xiao Luomo also had his own place.

Yang Xinxin asked, "Xiao Luomo, how long will it take for you to be able to collect full energy!" ”

Now that Mom and Dad already know their identity, there is no need to hide it.

Xiao Luomo replied: "Now we haven't even collected half of it, we have to continue to work hard." Hey, I don't know what's going on with the meow planet now, meow! ”

Xiao Luomo's voice was a little low, obviously homesick.

The atmosphere at the dinner table immediately froze, and Yang Xuewen saw this and immediately began to adjust the atmosphere.

"By the way, it's time to give pocket money to Tong Tong and Xinxin again."

Yang Xuewen took out two fifty yuan and handed them to Yang Tongtong and Yang Xinxin.

Yang Tongtong and Yang Xinxin also laughed, but Yang Xinxin suddenly asked curiously, "Dad, why don't you give me and my brother gold?" ”

Yang Xuewen was stunned, what, give gold?

This is really worthy of you, Yang Xinxin.

Yang Xuewen opened his mouth and said: "Why do you want gold in your heart? ”

Yang Xinxin took the chopsticks and replied: "Because gold and silver were used in ancient times!" Why is cash used in modern times? ”

Yang Xuewen smiled and explained: "In ancient times, it was not exactly gold and silver, you must know that in ancient times, there was money similar to RMB, and people at that time turned it into a silver ticket. ”

"Silver ticket?"

Yang Tongtong also began to sit upright, knowing that his father was about to start popular science again.

Yang Xuewen continued: "Silver bills are banknotes issued by ancient Chinese ticket numbers, and those with silver taels are called silver bills, and those with coins are called money bills. The earliest banknotes appeared in the Northern Song Dynasty and were called Jiaozi. Before the Northern Song Dynasty, if there was a lot of gold and silver, it would encounter very bad things.

For the sake of safety, in the early years of the Northern Song Dynasty, there were "silver ticket shops" in Chengdu, Sichuan Province that operated cash custody business for merchants carrying huge sums of money. The depositor delivers the cash to the shopkeeper, and the shopkeeper temporarily fills in the amount of cash deposited by the depositor on the roll made of paper, and then returns it to the depositor, and when the depositor withdraws the cash, he pays 3% of the interest paid to the shopkeeper for every 30 yuan of interest.

This kind of paper coupon that temporarily fills in the deposit amount is called a "silver ticket". At this time, the "silver ticket" is only a deposit and withdrawal certificate, not a currency.

The convenience of silver tickets has been sought after by many people, so silver tickets have gradually become the ability of credit currency, and finally become something recognized by the public. ”

Yang Xuewen paused and continued: "However, with the increasing number of silver tickets, many bad people appeared, they did not speak of credit, malicious fraud, and disappeared after abusing the silver tickets, resulting in the inability to exchange silver tickets, so that depositors had to think of the court for help, so there was something later."

That is, during the Jingde period, Zhang Yong, the governor of Yizhou, rectified the silver ticket shops, eliminated the lawbreakers, and operated them exclusively by 16 wealthy merchants. At this point, the issuance of "silver tickets" was recognized by the government.

So to this day, our currency actually plays the role of a silver ticket. ”

Yang Tongtong and Yang Xinxin didn't seem to understand after hearing this, and Zhang Jing also added: "Although the value of gold and silver has fluctuated, they can be described as safe-haven materials. ”

Yang Xin asked curiously, "Then what are the avoidance materials?" ”

Zhang Jing thought for a while and explained: "That is to say, with the change of the market, the price of materials will not fluctuate too much, such as gold and silver, this is a safe-haven material." ”

Yang Tongtong and Yang Xinxin understood, and then put all the pocket money in their bags.

More often, Yang Tongtong's pocket money for a week is basically to buy snacks for his sister in addition to buying stationery.

After eating and exercising a little, Yang Xinxin and Yang Tongtong went back to the study to do their homework, and when they were doing their homework, Yang Xinxin asked Yang Tongtong: "Brother, do you want to go and see how this Jiaozi came about?" ”

Yang Tongtong was stunned for a moment and responded: "How did the dumplings come from?" Aren't dumplings made by kneading flour into balls and serving dishes? ”

Yang Xinxin rolled her eyes and said dissatisfiedly: "Your homophonic stalk is not funny at all. ”

Yang Tongtong came to his senses and said, "You're talking about Jiaozi!" Well, actually, I also want to know how Jiaozi came about. ”

After speaking, the two of them looked at Xiao Luomo who was sleeping with ill intentions.

After Xiao Luomo felt his gaze, he woke up in an instant, and he was all furious.
