"The Hyuga incense burner produces purple smoke, and the waterfall is hung in the distance. The flying stream went straight down to 3,000 feet, and it was suspected that the Milky Way had fallen for nine days. ”

Yang Tong's Chinese teacher said after reading this poem on the podium: "Children, this is the Tang Dynasty poet Li Bai's "Wanglu Mountain Waterfall", do you know what this poem means?"

Everyone shook their heads and responded, "I don't know!"

The teacher smiled and continued: "This poem means that the incense burner peak produces purple smoke under the sunlight, and the waterfall hangs in front of the mountain like white silk in the distance. The waterfall on the high cliff seems to be thousands of feet long, making people think that the Milky Way is pouring down from the sky to the world. ”

All the children showed a look of surprise, they knew how long a foot was, but how many thousand feet was?

Yang Tong raised his hand, and the teacher immediately said, "Yang Tongtong, do you have anything to say?"

Yang Tong said: "Teacher, I have been to Lushan, is the waterfall in Lushan really as high as several thousand feet?"

Last year, my father took my mother, myself and my sister to Lushan, so Yang Tong asked his own questions.

The teacher smiled and replied, "Yang Tongtong is a very good question, Yang Tongtong, you sit down first, and the teacher will tell you if the Lushan Waterfall is really thousands of feet high."

After Yang Tong sat down, the teacher continued: "In ancient times, the length of a foot was different in various dynasties. For example, in the Tang Dynasty where Li Bai lived, the length of one foot was 29 cm to 30.4 cm. That's a few thousand feet, that's very high.

And Li Bai uses exaggerated techniques in this poem, not that the waterfall in Lushan is thousands of feet high.

Kids, do you understand? ”

After listening to it, everyone suddenly realized that it was an exaggerated technique here, and the Lushan Waterfall was not so high.

After Yang Tong listened, he thought of the Li Bai he had seen, how could he like to exaggerate things?

After returning home from school, Yang Tong told his sister Yang Xin about it.

Yang Xin immediately said: "Brother, let's go and see Li Bai through the Rubik's Cube!"

Yang Tong nodded, and then the two shouted out the Rubik's Cube, which scattered a white light and took them away from the modern world.

When they opened their eyes, they found themselves on a dock, where is this?

I saw someone shouting, "It's time to get on the boat!"

Yang Xin and Yang Tong were inexplicably squeezed onto the boat, and then sat down on the boat.

They listened to the sounds of conversation coming from around them, and their faces showed strange expressions.

Yang Tong asked a scholar next to him, "Uncle, is this a boat to Lushan?"

The reader smiled: "How is this a boat to Lushan, this boat is going to Xiangnan."

Yang Tong and Yang Xin glanced at each other, with a puzzled face, where is Xiangnan?

They were about to ask when they heard a pop and something fell into the water.

A knight's sword fell into the water, but the knight did not panic at all, he took out his knife, left a mark on the boat, and sat back in his place.

Yang Tong asked curiously, "Uncle, your sword has fallen, don't you want it?"

The knight replied confidently, "I have carved a mark on the ship, and if I get to the shore, I will be able to retrieve my sword by jumping into the water from the mark I have carved and looking for it."

Yang Tong was stunned after hearing this, can it still be like this?

Yang Xin immediately spoke: "But your sword was dropped elsewhere, how can you get your sword back if you make a mark from the ship?"

Yang Tong also chimed in: "The ship has been moving, but your sword has sunk to the bottom of the water and will not move with the ship, how can you find your sword?"

The knight was still very confident, and replied, "Hey, you don't understand. I have carved a mark on the ship, and when I reach shore, I will be able to retrieve my sword by jumping from the mark I have made. ”

Yang Tong and Yang Xin were dumbfounded, how could this person be as stubborn as a donkey?

Yang Xin said: "Brother, this person is like the Wei people who have been going north!"

Yang Tong nodded and responded, "Yes, it's really similar, but it's a little different."

Yang Tong can't tell what is different, but he feels that it is still a little different.

The others also told the knight that you can't get your sword back like this. While it is not far yet, let the boat stop, there is still a chance.

But this chivalrous man didn't listen to persuasion at all, and everyone stopped persuading him.

After arriving at Jinling, everyone got off the boat and did not leave, and the knight jumped directly from the mark he had carved on the ship.

It was a long time before he came to the surface, and with a dejected look on his face, he shouted, "Where is my sword?" Why can't I find my sword? ”

Yang Xin said on the shore: "I told you that the place where your sword fell will not move with the ship, so you don't listen!" Now I regret it, I can't get my sword back! ”

The man said angrily, "Did you take my sword, give it back to me, give it back to me."

Yang Xin said to Yang Tong: "Brother, is he crazy?"

Yang Tong was speechless and led his sister away, while the man came out of the water and began to chase Yang Tong and Yang Xin.

Yang Xin and Yang Tong were not panicked, they had treasures sent by the Rubik's Cube.

The two of them began to run towards the place where there were fewer and fewer people, and this man kept chasing and shouting, "Give me back my sword, return my sword, like a madman."

The man chased him under a willow tree and shouted, "You two little broken boys, return my sword to me!"

Yang said angrily: "We didn't take your sword, you fell into the water by yourself."

The man had completely lost his mind: "I don't care, it's what you take, hurry up and return my sword, otherwise don't blame me for being unkind to you."

Yang Xin took off the long rope from his pigtail, and Yang Tong also took off the bracelet on his hand.

Before they could make a move, a middle-aged man appeared and kicked him away.

The middle-aged man flicked his sleeves and said angrily: "In broad daylight, you are an adult man bullying two children, what kind of system do you become."

The man immediately said, "They have taken my sword, and I just want them to give it back to me."

The middle-aged man looked back at Yang Xin and Yang Tong and asked, "You took his sword?"

Yang Xin immediately said: "No, my brother and I didn't take his sword."

Then, he told the middle-aged man exactly what happened.

After hearing this, the middle-aged man looked at the man who fell to the ground and reprimanded: "How can there be such a stupid person as you in this world, it is simply unreasonable."

Then he said to Yang Tong and Yang Xin: "Let's go, don't pay attention to this kind of person."

The man who fell to the ground wanted to catch up, but he didn't dare, showing an unwilling expression.
