Shen Wenjun walked out of Linjiang Pavilion with everyone from Xiaoxiang Academy and came to the backlight.

It was close to noon, and the sun was shining in the sky, hitting the shadow of Linjiang Pavilion on the square.

The floor tiles in the square are three feet long, and the shadow covers exactly sixty-three floor tiles, so the shadow is about twenty feet long.

Then, she took a bamboo pole as a reference, and stood under the Linjiang attic, and calculated that the bamboo pole was one zhang long.

According to the law of the sun, at the same time, the higher the object, the longer the shadow, and these two quantities are related quantities, and the larger one quantity becomes, the other weight also increases, forming an equal proportional proportion;

The height of the bamboo pole is compared with the height of the bamboo shadow, which is equal to the height of the Linjiang Pavilion than the height of the shadow of the Linjiang Pavilion, and the shadow is one and a half times that of the real thing, so the shadow of the Linjiang Pavilion is twenty zhang long, and the height is thirteen zhang and one foot.

"Lord Liu, I have obtained that the Linjiang attic is thirteen zhang and one foot high through conversion, and there may be a deviation of half a foot, you are right?" Shen Wenjun asked.

Liu Boyong exclaimed: "I personally supervised the repair of this Linjiang Pavilion, and it is indeed thirteen zhang high, plus the golden tripod of the attic, it is just one foot more, Mrs. Song is really powerful." ”

Shen Wenjun looked at Cao Guojin with a gloomy face, "Dean Cao, this second round of my Xiaoxiang Academy is going on the next journey first." ”

Cao Guojin only whispered: "Please also ask for questions." ”

"Since your academy has a problem measuring height, then I will give you one back." Shen Wenjunyu put a finger on the pennant pole in the square, and rushed at Ning Yehong beside him.

Ning Yehong walked to the flagpole, jumped up with a knife, cut the flagpole into pieces, and measured the length of the vertical flagpole with a ruler: "This section, there are three zhang." ”

"Dean Cao, it is known that this section is planted in the ground and is three feet high, so how high is the flagpole in total? You can find a reference, but you are not allowed to measure the broken pole, please solve the problem. Shen Wenjun asked, beckoned again, lit half a pillar of incense and began to time.

Even though Cao Guojin came to the flagpole with a few students, looked around the broken pole and looked around, turned and turned, and the incense burned little by little, they had no clue.

Seeing that the time was approaching, Zeng Hou was anxious again, "Where have you learned the scriptures and chapters on weekdays?" Solve the problem! ”

His urging undoubtedly increased the psychological burden of Cao Guojin and others, and sweat began to break out on their heads.

"Teacher, this is simply an unsolvable problem, the broken rod is so arbitrary, who can know its length?" Cao Guojin glared at Shen Wenjun: "You are eager to win, and you don't need to come up with an unsolvable problem to make it difficult for us!" ”

Shen Wenjun didn't bother to taunt them, so he just turned his head and said from Qin Ruo on the side: "He, he must not have hooked his wife's ass." ”

Qin Ruo covered her mouth and snickered, "That's it, it's ......"

"Half a pillar of incense burns out, the time has come, this second competition...... Uh, Xiaoxiang Academy wins. Liu Boyong pointed to the burned incense burner and announced loudly.

"Wait!" Cao Guojin stopped, "The premise of judging victory is that this problem can be solved, if he deliberately comes up with an unsolvable problem, we will not be convinced!" ”

"Okay, then you'll be convinced!"

Qin Ruo walked to the flagpole, picked up the broken half, put it on the port, and placed it in a right-angled triangle, she said: "It is known that the height of the vertical pole is one zhang three, and then the shadow of the vertical pole is one zhang eight, and the length of the broken pole is about two zhang two, and the broken pole is added to the vertical pole, then the original height of the flagpole is three zhang one, and there may be more than half a foot smaller, if you don't believe it, Lord Liu can measure it himself." ”

Liu Boyong took the ruler and compared it in front of everyone, and measured that the length of the flagpole was indeed three feet and one and a half feet.

The Confucians of Lingyin Academy were speechless again.

"Hmph, you don't have to be proud, riding and shooting, arithmetic, in the eyes of our academy, but the supplementary course to cultivate sentiment, what the academy really teaches is literature, the third poetry competition, the old man will personally compete with you, and you will be convinced!"

Everyone returned to Linjiang Pavilion again and sat down.

"Liu Sheng, hurry up and come up with the question, the old man is in a hurry at the moment!" Zeng Hou urged.

Liu Boyong pointed to the inscription in front of the pavilion and said with a smile: "The previous article "Linjiang Pavilion Preface" that 'the worries of the world first, the joy of the world after the world's happiness' famous sentence, make Hangzhou Linjiang Pavilion famous all over the world, today all the Confucian scholars and talents gathered again, why not take the ascending as the theme, write a famous poem hanging on the hall, so that the name of Linjiang Pavilion can go to the next level? ”

"Good!" Zeng Hou walked out of his seat, "Fortunately, the "Preface to Linjiang Pavilion" is prose, otherwise the old man really wouldn't dare to ink in front of this famous article, so the old man will compose a poem and give it to this pavilion!" ”

As soon as these words came out, all the Confucians were sitting in danger and listening.

Seeing Zeng Hou come to the fence, he looked at the sea for a moment, and opened his mouth to chant:

"Canghai Building shines brightly, and Qianjiang Pond is white and clear. The sound of the waves slowly moored the passenger ship, and the willow was green and green with red flowers. Scratching the head knot and asking the sky, carrying a pot to sell wine meets Hakka. Through the sun and thousands of miles of Changhong, Qingyun hangs down half a pot of yarn. ”

"Good!"

"It is worthy of Zeng Lao, and the export is a famous poem through the ages!"

"Quick! Quickly record the teacher's writings, and I will engrave them on the pillars for the world to enjoy! ”

Don't say it's them, even Nangong Yue and Liu Xinnan can't help but praise the good poems.

"Don't be silent, aren't you talented women, it's your turn to compose poetry." The Confucianism of Lingyin Academy seized this opportunity of shame and kept urging and mocking Nangong Yue and Liu Xinnan.

Liu Xinnan gritted his teeth and looked at Nangong Yue: "Do you have good poems?" ”

Nangong Yue was extremely unconfident, "Yes, yes, but ...... Can...... Alas...... "She had to turn her head and ask Song Che beside her for help.

Song Che frowned, and said secretly in his heart: This old thing really has some ability, even if he can find Tang Shi to fight against him, he will draw with it at most, if he wants to surpass him in terms of attainment, he must be a famous article that has never been seen before or since.

"That's it......" Song Che leaned closer to Nangong Yue and whispered twice in her ear.

Nangong Yue sighed lightly and nodded, got up and said to Liu Boyong: "Lord Liu, Mr. Zeng's "Spring Hope" has taken the lead, and the beautiful scenery of Linjiang Pavilion in the daytime has been appreciated, even if I have written good poems, it is difficult to surpass, so I want to write poems after nightfall, so that a day, a night, a sun, and a bright moon can form a more contrast." ”

"If you can't compare, you can't compare, what kind of day and night? I see, they clearly stalled for time first, so that they could come up with good poems to deal with it! We were always improvised! ”

"Zeng Lao's poems, looking at the whole Jiangnan, who can compare with it? In my opinion, you should admit defeat early! ”

"No!"

Zeng Hou raised his hand and spoke, "She's right, the sun is in the sky and the moon is the night, it is an excellent contrast, the old man makes poems during the day, she should make poems for the night, wait a minute, it's okay!" ”
