But I saw Feng Fuchang shaking his head, but said, "That's good! It's just good, in this way, our Fengyang family can be regarded as relatives. ”

Zhu Zhixian said with a smile: "In this case, how about handing over this matchmaker to this county?" ”

Everyone said in unison! Zhu Zhixian said with a smile: "What are you doing outside the wind, you two, announce this good news to everyone!" ”

Feng Fu often made a gesture of please, Yang Qingyun hurriedly followed the battle, Feng Fu often said loudly: "Everyone, tell you a good news!" ”

Suddenly, the banquet stopped, everyone listened to Feng Fuchang talking, only to hear Feng Fuchang say: "I discussed with my brother Yang just now, and decided to propose marriage to the little lady of the Yang family and my son Feng Manlou, and the two families will be good for Qin and Jin!" ”

Yang Qingyun also said: "The old man has a daughter, today you will be a witness, and I will give it to the young master of the Feng family......"

"Wait!" A voice shouted, everyone followed the reputation, but saw a little lady, who was quite abnormal, stood up, finished saluting Feng Fuchang and Yang Qingyun, and said: "If you want me to marry this nerd, I won't agree!" Unless, he answers me a few questions first! ”

Yang Qingyun's old face turned red and red, and he shouted: "Cai'er, don't be rude!" ”

Feng Manlou heard it, what kind of moth is this, but marriage is about the words of the matchmaker of the parents, and now the conditions are fully met, and I am not afraid that this little lady will not agree. It seems that chasing girls in this era only needs to get rid of the father-in-law. However, this little lady wouldn't be asking me to write a poem, if it were, it would be a little difficult. Make some poems, I still have some stock in my stomach, so it's a big deal to memorize a few articles and fool the past. If it's the right pair, it's over, and you have to lose the bottom all of a sudden. Looking at this situation, it seems that the possibility of losing the bottom is very great.

But now the Feng family is squeezed by the little lady and can't come to the stage, everyone has looked at Feng Manlou, it seems that if you don't lose some people today, you can't get off the stage.

Feng Manlou stood up, smiled at everyone, and said, "It's okay, it's okay!" ”

In fact, he secretly complained in his heart, but he said: "I don't know that Little Lady Yang has advice!" ”

As soon as everyone heard that the old lady was going to talk to the little lady, they were interested, and they wondered if this little lady could stump the old lady.

But I heard Yang Hongcai say generously: "I don't dare to advise, I just want to take the school test casually." But you have to make it clear first, if you can't answer it, you should stop thinking about it as soon as possible. If the answer comes up, I'll agree to it!

Feng Manlou looked at the situation, no matter what today, he had to agree, nodded, and said, "Little lady of the Yang family, please rest assured!" The wind does it! ”

Feng Manlou was secretly anxious, but at this moment, Yang Hongcai was secretly thinking in his heart, this flashy prodigal kid, he must not be able to get off the stage today. If the poem is right, this is a jinshi, hand-picked by the official, it must be difficult. You'll have to find another way. After thinking about it, he said: "Today, I won't test your poetry, nor do I test you right, I just want to test you a few common questions!" ”

When Feng Manlou heard this, he breathed a sigh of relief in his heart and said, "It's okay, it's okay!" ”

But I heard Yang Hongcai ask: "Once upon a time, there was a temple, and there were three monks in the temple. Three monks picked up three loads of water in three days, and later there were nine more monks, and asked the twelve monks how many loads of water they picked up in twelve days! ”

When I heard the wind all over the building, I was weird, so simple?! I couldn't believe my ears, and said with an incredible face: "It's so simple, are you sure you're not wrong?" ”

But when I saw Zhu Zhixian and the Lord Bo County Lieutenants, their faces were full of black lines, these numbers had already embarrassed me, how could it be so simple.

At this time, a young man who looked like a young man stood up and said, "Young Master Feng, this question is indeed too simple. If you think about it, three monks carry three loads of water in three days. Twelve monks for twelve days, isn't it just to pick up twelve loads of water! ”

When Zhu Zhixian heard this, he nodded again and again, and said: "Exactly, three monks pick three loads of water in three days, and ten monks are ten loads of water in ten days." Twelve monks in twelve days is twelve dans, yes, why didn't I think of it! ”

Everyone said that it was so simple, but they heard Feng Manlou laughing: "Don't be impatient, everyone!" Twelve monks for twelve days, it should be forty-eight loads of water! I didn't expect Yang Xiaoniang to come up with such a simple question! ”

This question is actually a simple multiplication and division, and the main thing is to test people's reactions, which is actually to lead people to the wrong answer with their habitual thinking.

When everyone heard this, they suddenly realized and said, "So that's what happened! ”

Zhu Zhixian's face suddenly turned red, it turned out that he had also been fooled, this little lady seemed to be really a little witty! Feng Manlou thought in his heart, it turned out that they were all math problems, so simple, many third-grade students could answer them.

Yang Hongcai didn't expect Feng Manlou to answer so quickly, and he was also shocked in his heart, it seemed that there would be some more problems. After thinking about it, he said, "Young Master Feng is really wise. Now let's take a look at the next question. ”

"Everyone, please look, there is a locust tree in the middle of the yard, I want to ask Young Master Feng, how do you know how tall this locust tree is? The premise is that you are not allowed to cut down this tree, you are not allowed to climb this tree! Yang Hongcai said!

That's the problem. Suddenly, the people in the banquet exclaimed, this is too difficult, don't let you climb this tree, you have to know how tall this tree is! How is this possible?

Feng Manlou thought about it, this is a simple triangle problem. said: "Simple! I need a ruler to measure it! ”

Everyone was shocked, how is this possible, no one is allowed to climb this tree, and no one is allowed to cut down this tree, how can it be measured! But Feng Manlou is full of confidence.

Yang Qingyun smiled embarrassedly: "Virtuous nephew, if you are embarrassed, the old man will go back and teach this uneducated Y head a lesson." Don't worry, even if there is no way to solve this problem, the old man doesn't blame you, the old man can still call the shots in this marriage! ”

Feng Manlou shook his head and said, "Uncle Yang, don't panic, the little nephew has a way!" After speaking, he called Xiaoyun to find a ruler and a rope.

Soon, the ruler and rope were found. Feng Manlou took a chopstick and came to the middle of the courtyard. Everyone followed one after another, to see how this new Kejin Shi master, why didn't he go up to the tree, didn't cut down the tree, and measured how tall this trunk was!

I saw Feng Manlou put the chopsticks up straight and put them on the ground. A shadow was formed on the ground.

"Xiaoyun, measure how long the shadow is!" Feng Manlou commanded.

Xiaoyun measured it for a while, and Feng Manlou wrote down the size. Let Xiaoyun measure the shadow of the tree again, and then make a mark! Feng Manlou marked the rope and began to measure it, and soon wrote down the size. Then I measured the size of the chopsticks. So he went back to the house.

Everyone was anxious for a while, and Yang Qingyun asked, "Okay." Virtuous nephew? ”

Feng Manlou nodded and said, "It's almost!" ”

After speaking, he walked up to Yang Hongcai and said, "Little lady Yang, I already know how tall this tree is. This tree is a total of three zhang seven inches and five, of course, there may be a little error, but it must be between three zhang six inches and three zhang seven inches. ”

As soon as everyone heard this, they measured how tall the tree was. Immediately exclaimed, but many people still had skeptical eyes.

Feng Manlou said with a smile: "I know you don't believe it, you can cut down the tree now, measure it immediately, and see if it is so high as I said!" ”

Yang Qingyun was also shocked in his heart, this wind is full of buildings, it won't be casual nonsense! Yang Hongcai asked, "How do you figure it out?" ”

Feng Manlou smiled: "It's very simple! This is a triangle formed by the tree, the shadow, and the distance between the shadow and the tip. And the distance between this chopsticks and the shadow of the chopsticks, and the distance between the top of the chopsticks and the top of the shadow, is enough to form another triangle. Two triangles are similar triangles! Then they exist in the same proportion. I measure the length of the chopsticks, the length of the shadow of the chopsticks, and the length of the shadow of the tree to calculate the height of the tree! ”

Yang Hongcai was also amazed when he heard it, he was just embarrassed for him, even if he had a certain amount of research on the number of techniques, he didn't expect to be able to measure it like this! But the similar triangle he was talking about, I don't seem to have heard of it.

Yang Hongcai asked, "What do you mean by this similar triangle?" ”
