Traveling to the ancient harem

In the Hibiscus Garden, Huang Ye sat on the swing with a heavy heart. Hong Dou gently pushed her on the swing from behind, "Alas."

"Miss, you sighed a lot today." Hongdou reminded her that children grow up quickly. Now Hongdou's face has become fleshy, and she is much stronger. She has also returned to her original nature, becoming lively and talkative. She would do horse stance in the yard every morning, and go to Qingsangju to practice martial arts with Master Wu in the morning. The weapon she chose was a long whip. In her words, knives and swords are not easy to carry in some occasions. The long whip is usually worn around the waist as a belt, and it can be used as a weapon when encountering something. It is practical. Huang Ye kept praising her for her good choice, and she walked with her head held high for a few days, like a proud goose.

The Huang family has a happy event these days. Because of his outstanding ability in the Hanlin Academy, Huang's father was transferred to the Ministry of Revenue under the operation of the old man. The Huang family has been officials in the court for generations. Each of them has outstanding abilities but never takes sides. They are staunch royalists and are highly valued by emperors of all dynasties. Although their official positions are not very high, they are all in relatively important positions. Like the old man, he only reached the position of assistant minister in this life. If nothing unexpected happens, Huang's father will also be an assistant minister in the Ministry of Revenue in the future.

When Huang Dad first arrived at the Ministry of Revenue, he started from the grassroots level, which was to re-check the account books of the Ministry of Revenue for the past ten years. The staff of the Ministry of Revenue also knew that he was just transitioning at the grassroots level, but this was something that everyone who entered the Ministry of Revenue had to go through. After all, the Ministry of Revenue was in charge of the operation of money and grain throughout the country, and being able to do accounting was the most basic skill.

"Dad has been coming back very late these past few days and he looks very tired. I really want to share some of the burden for him." Huang Ye sighed again. Accounting in this dynasty was very troublesome. The numbers from one to ten were all in traditional Chinese characters, which were difficult to write and the accounts were messy. It was very laborious to look at the accounts. With her father going out early and coming back late, it would probably take him a month to finish a year's accounts, let alone ten years' accounts.

After thinking about it, she still felt sorry for her father. She walked into her study, called Hongdou in to grind ink, and carefully wrote down the Arabic numerals from one to ten, and then made a table. This dynasty had multiplication formulas, and she wrote the multiplication formula again with Arabic numerals. After thinking about it, she made another table. All kinds of income and expenditure, details, and notes were clear at a glance. She waited for her father to come back in the evening to see if he was willing to learn.

The sky gradually darkened, and Father Huang came back from outside with heavy steps. He first went to the old lady's Funing Hall to pay his respects to the old lady. When he arrived, he saw that the whole family was there, waiting for him to have dinner. He had to suppress his fatigue and chatted with everyone for a while after dinner. When he was about to say goodbye and go back to his own yard to rest, Huang Ye called him.

"Ye'er, is there something you want to tell me?" Dad Huang touched Huang Ye's hair lovingly and asked gently.

"Grandfather, Daddy," Huang Ye took out a few pieces of paper and showed them. "This is what I have figured out these few days. Maybe it can reduce Daddy's work of checking accounts. Can you help me see if it works?" She put the papers on the table that had just been cleaned up after dinner. The old man and Mr. Huang Huang Zihong were curious and gathered around the table. They watched Huang Ye pick up a piece of paper and start to explain. She first explained the simple Arabic numerals, then explained the writing and use of addition, subtraction, multiplication and division, and then introduced the very common financial statements in modern times.

About a quarter of an hour later.

The old man and his son looked at each other, and then looked at Huang Ye at the same time, "Ye'er, is this something you came up with?" The old man spoke first.

"Yes." Huang Ye said innocently, "Ye'er sees that daddy works so hard every day, so I wonder if I can use a simple arithmetic method to replace the complicated calculations. I've been thinking about it for several days. Do you think it's feasible, Grandfather?"

"I think it's OK." Hong Ge'er admired his sister so much. "If our teacher who teaches counting sticks used simple numbers like this, we would definitely learn it very quickly."

The old man suddenly felt that the iron walnut in his hand was no longer fragrant. Hongger's thoughts were just childish. He and his son thought further: if this arithmetic was popularized, it would be a major change in history, and it would be recorded in the history books.

"Ye'er." Father Huang's voice was a little trembling: "Dad, can you bring this to your colleagues for research?"

"Of course you can, but Daddy has to study this idea thoroughly in advance, and then share it with your colleagues. After all, this is Daddy's idea." Huang Ye blinked his black and smart eyes cunningly and said playfully.

"The child is trying to give you credit." The old lady instructed her son.

"Son knows, but is this okay? After all, it was Ye'er's idea."

"Ye'er is still young, and telling others might cause trouble." The old man asked Huang Ye: "Ye'er, do you think that grandfather is right?"

"Yer won't mind. I only care about it because I feel sorry for Daddy's hard work. I just want Daddy to be healthy."

"This child." The old lady was very pleased. "Ye'er is really a very smart and filial child. Our Huang family's ancestors are very happy."
