At the back door of Qiao's mansion, Qiao Muxue and Qiao Muyu waited anxiously, and their eyes were put into the distance from time to time.

Not long after, the little maid Cui'er Lan'er ran back from a distance.

Cui'er shouted as she ran, "Miss, Miss, we bought it back." ”

Before Cui'er could continue to shout, Qiao Muxue nervously made a "don't shout" action, the two sisters didn't want their father to know about this.

"Don't talk, don't take it out, go back to the room first." Qiao Muyu said to the two little maids who approached.

A group of four people cautiously returned to Qiao Muxue's room from the back door of Qiao's mansion, and after closing the door and window of the room, under the gaze of Qiao Muxue and Qiao Muyu, Cui'er Lan'er each took out two books that were not too thick from their sleeves.

These four books are the four books currently on sale at Wenhua Bookstore: "Translation of Traditional and Simplified Common Characters", "Elementary Mathematics", "General Knowledge" (Traditional Chinese Edition), and "Common Sense" (Simplified Chinese Edition).

Modern people have probably heard the saying "a woman is virtuous if she is not talented".

"A woman's lack of talent is virtue" comes from Zhang Dai's "Public Sacrifice of Mrs. Qi's Wen" in the Qing Dynasty: "Mei Gong said: A husband is virtuous, and a woman is virtuous." This statement is very uncertain. ”

At the end of the Ming Dynasty, Chen Jiru (born in 1558) said: "Women are literate, and those who can understand righteousness are virtuous, but they are rare; Others like to read music books, stir up evil hearts, and even dance and write the law, and do no ugly things, but it is better to be illiterate, and to keep clumsy and secure for healing. A woman's lack of talent is virtue. It can be said that it is very good. ”

In fact, literati scholars like beautiful women, and on this basis, it would be better if women knew how to play the piano, chess, calligraphy and painting, and they had a common language.

Qiao's family is a scholarly family, Qiao Muxue and Qiao Muyu's two sisters are literate, and both have a certain literary talent.

After learning about the Mandarin Bookstore, the two sisters were very interested in the simplified Chinese characters of the People's Army and the books sold by the People's Army, so they asked Cui'er Lan'er to buy the books back.

The two sisters didn't dare to let their father know about buying books, in Qiao Rong's mouth, the People's Army was still a "thief", and they would not let the two sisters buy books sold by the People's Army, so they had to do it secretly.

The four books sold at Mandarin Bookstore were close to the cost price, and the prices were so low that the two sisters could easily buy four books with their pocket money, and now the two sisters wanted to see the contents of the four books.

With nervousness and curiosity, Qiao Muxue opened the first book "Translation of Traditional and Simplified Common Words".

The content of this book is very simple, it is a very thin book with thousands of commonly used words translated from traditional and simplified, but because simplified Chinese characters have changed a lot compared with traditional Chinese characters, it takes a lot of time to learn simplified Chinese characters, especially if you have learned traditional Chinese characters and then learn simplified Chinese characters, there will be a lot of inconvenience in learning and using.

For this book "Translation of Traditional and Simplified Common Words", Qiao Muxue and Qiao Muyu just looked at it, and neither of them had the idea of learning simplified Chinese characters for the time being, so they put down "Translation of Traditional and Simplified Common Words" and opened "Elementary Mathematics".

There is an introduction to the book in the previous article of "Elementary Mathematics", mathematics is the meaning of arithmetic, and the various mathematical symbols in the book dazzled the two sisters a little, so they set their eyes on the third book "Common Sense" (traditional Chinese version).

"What? Is the earth round? Qiao Muyu let out a sound in surprise.

Qiao Muxue was also surprised, she thought that "the sky is round and the earth is round", while Qiao Muyu thinks that the earth is flat and goes directly to the end of the world, but "Common Sense" writes that the earth is round, people live on a round ball, the moon is a ball smaller than the earth, and the sun is a ball much larger than the earth.

In this section of general knowledge, there are several pictures, including pictures of the earth, the moon, and the sun, as well as simple drawings of the earth, and the general territory of the Ming Dynasty, the People's Army, and the alien races.

The first verse alone made the two sisters almost say something in amazement, they couldn't believe that the earth was round, and that people could still stand on the earth with their heads down.

Not only the two sisters Qiao Muxue and Qiao Muyu, but also the literati and scholars in the entire Guangzhou City quarreled over the first section of "Common Sense".

The vast majority of literati scholars did not learn simplified Chinese to participate in the People's Army's imperial examinations for the time being, but there were also idle people who spent money to buy all four books and take them to a friend's party to read together, mainly to criticize the People's Army's books.

"Translation of Traditional and Simplified Common Words" and the almost incomprehensible "Elementary Mathematics" are directly skipped, and they are both studying "Common Sense" (traditional Chinese version), and the first section of "Common Sense" is about the introduction of the earth, which directly makes the literati scholars quarrel, Qiao Muxue and Qiao Muyu The two sisters can hardly believe that the earth is round, and these literati scholars can hardly believe that the earth is round.

"The earth can't be round!"

"The earth should be flat, and the sky is like a jade bowl upside down on the earth."

"No, the earth is flat, and the sky is flat, endless."

Not only did the literati scholars disagree with the introduction of the earth in the Common Sense, but even the literati scholars argued among themselves because of their different views, and none of them could be recognized by the majority.

The best way to solve this argument is to send a fleet of ships to sail around the earth, set off to the east and back from the west, which is a better way to prove it, as for the method of seeing the flagpole on the sea first and then seeing the ship, it cannot be fully proved.

The literati and scholars argued and argued, and when they could not reach a conclusion that everyone could agree on, they put the matter aside, and soon the world map in the first section of Common Sense attracted everyone's attention.

No matter how arrogant the intellectuals of the old era were, they also knew that there was heaven and earth beyond the Ming Dynasty, that there were alien people alive, and that they could see alien people in the city of Guangzhou.

In the world map, the territory of the Ming Dynasty is located in the center of the world map, which makes a group of literati and scholars feel that the Ming Dynasty is worthy of being the kingdom of the Celestial Empire, and it is actually located in the center of the earth, which is the richest place.

After lamenting the position of the Ming Dynasty, everyone sighed about the vastness of the earth, they thought that the territory of the Ming Dynasty was already large enough, but they did not expect that the land was more than ten times the size of the territory of the Ming Dynasty.

They only have the feeling of "big" in their hearts, and they hardly think about how good it would be if they occupied the land outside the Ming Dynasty, and if they occupied those lands, all the people under the Ming Dynasty would need to worry about the land anymore.

What's more, literati and scholars still think that the land outside the Ming Dynasty is barren, and all the rich land is in the Ming Dynasty, and there is no need to go to the land outside the Ming Dynasty.

It is very interesting that the literati did not believe that the earth was a sphere, but they believed the contents of the simple world map......
