"Mother, why did you eat so well tonight?" Tang Shishi came in from outside, and saw that the food on the table was very rich, so she looked at Li Yushi, who had just put down a plate of dishes, and asked.

"Huh." Li Yushi heard Tang Shishi's question, smiled and said, "Your father is going to eat at home today, so I prepared two more dishes, and today is all the dishes that your mother and I cooked personally." ”

"Ah," Tang Shishi was very surprised when she heard that her mother was cooking today, and all the dishes she cooked: "Today is my mother's own cooking, so I will eat a little more today." ”

In the past, Li Yushi still knew how to cook, usually one dish, or two dishes, unlike today, there are a total of eight dishes on the table, all of which are made by Li Yushi alone, which is relatively rare.

Li Yan, who was on the side, heard what Li Yushi said, asked a key question, and said, "Uncle is coming back today?" ”

"Hmm." Li Yushi heard Li Yan's question, nodded and said, "Yes, since the day Tang Xiu and them came a few days ago, he had dinner together at home, and the rest of the time is although sometimes he eats at home, it is relatively late, unlike when he came back early today." ”

"Hey." When Li Yan heard this, he couldn't help but sigh and said, "Uncle is really hard. ”

"Huh." Hearing Li Yan's words, Li Yushi smiled and said: "It's hard to work hard, it's not easy for a family to eat, but a person like him who is working for the court and being an official will be very hard at that time, but this is also a matter of no way, if you are an official in the court in the future, you will experience this." ”

When Li Yan heard this, he didn't say anything, but not long after Li Yan finished speaking, a dignified but amiable person entered the room, this person was none other than Tang Liwen.

As soon as Tang Liwen entered the room, he saw the sumptuous meal on the table, and said with a smile: "Haha, is today's dinner quite rich." ”

"Huh?" At this time, Tang Liwen noticed that Li Yushi, Tang Shishi, and Li Yan and others didn't seem to move their chopsticks, as if they were waiting for someone, and when he saw this, he immediately understood, and said, "Why don't you eat yet?" Are you waiting for me? ”

"What do you think?" When Li Yushi heard Tang Liwen's words, she said angrily: "Didn't you say that you were going to come back to eat tonight, no, the children are waiting for you." ”

"Huh? Oh haha, forget about that then. In that case, I'll sit down and eat, and I can't keep the children waiting. Saying that, Tang Liwen sat down beside Li Yushi.

After sitting down, Tang Liwen first took a chopstick to eat, and Li Yan, Tang Shishi and Tang Xiu began to move the chopsticks.

In ancient times, when juniors and elders ate at the same table, the elders moved the chopsticks first, or the elders said yes, and the juniors could move the chopsticks, otherwise this was a kind of disrespect, after all, the elders were older than you, and letting the elders move first was also a kind of etiquette for respecting the elderly; And in ancient times, there were also seats.

Getting back to business, everyone ate together for a while, Tang Xiu looked at Tang Liwen and asked, "Uncle, do you know the number of the Nine Palaces?" ”

"Huh?" When Tang Liwen heard Tang Xiu's words, he stopped the chopsticks in his hand and said, "The number of nine palaces?" I know this, what's wrong? ”

"Daddy. Let me tell you. Tang Shishi heard Tang Liwen ask, stopped and said, "Today, Mr. Xu Bai will teach us mathematics. Then Tang Shishi roughly told Tang Liwen what Xu Bai said today, as well as the number of the nine palaces.

"The number of the nine palaces is the task that Mr. Xu Bai gave us today, but Mr. Xu Bai has never told me about the number of the nine palaces. So I have been solving the number of the nine palaces before the meal. Tang Shishi finished speaking in one breath, and said that she couldn't help but be a little annoyed here.

"Oh, I see." Hearing what Tang Shishi said, Tang Liwen nodded and said: "The number of these nine palaces is one of the highest in mathematics, but one of the most difficult. So I don't know if you ask, and I don't have any research in mathematics. ”

"Still." Speaking of this, Tang Liwen looked at Li Yan and said: "I didn't expect Li Yan to answer such a strange question, what to add one plus one and wait for one, if this is known to the scholarly family in this county town, his face will turn green with anger." But this logic is irrefutable. ”

Tang Liwen was very curious about how Li Yan thought of this, so he asked, "By the way, how did Li Yan also come up with this logic?" ”

"That's it." Li Yan heard Tang Liwen ask, put down the dishes and chopsticks and said: "This has to be the credit of the question asked by Mr. Xu Bai, didn't he say grains, it reminds me of the original scene of drying grains, one of the scenes is very similar to this question." ”

"Oh? What scenario? Hearing Li Yan's words, everyone looked at Li Yan with curiosity, wondering what the scene was.

When Li Yan saw them like this, he smiled and said, "Isn't it necessary to collect the pile after the sun?" It can be dried in a large area, and it is very laborious to harvest one pile, so it is divided into two piles, or several piles, and then it is combined into one pile. ”

When everyone heard the scene Li Yan said, they were all surprised, they didn't expect it to be like this. Tang Liwen nodded and said: "Hehe, this is already a good logic, in many cases, some answers are often in the details of life, but most people will ignore it, and if you can find this, it means that you are careful." ”

"But this Xu Bai really doesn't have the appearance of being a gentleman, and he hasn't talked about the number of the nine palaces, so let you do the question yourself, there is only one number, but." Tang Liwen paused here and said, "That's fine, if you do it, he will teach you seriously." When you finish eating, Shishi, you come to my room, and I will give you a book, which has a record of the number of the nine palaces, maybe you can find the relevant solution here. ”

After saying that, Tang Liwen continued to eat, and Tang Shishi heard what Tang Liwen said and wanted to ask something, but Tang Liwen glared at him and said, "Eat, talk about something to eat." ”

Hearing this, Tang Shishi didn't ask anything, just like that, everyone quietly finished dinner, and after Tang Xiu's brothers and sisters finished eating, they went to the position of the stone table and sat and waited for Tang Shishi to come over with a book.

After Li Yan finished eating, he wanted to go back to the room to do something else, but he was pulled by Tang Shishi and said, "Xiao Yanzi, do you have something to do now?" If you're okay, come with me to get the book. ”

When Li Yan heard this, he wanted to say something, but he still didn't say so, but said teasingly: "What, are you afraid of the dark, or are you afraid of ghosts wandering at night?" Saying this, Li Yan made a grimace.

When Tang Shishi heard Li Yan's teasing words, and saw Li Yan's grimace, she immediately became angry: "You are afraid of the dark, you are afraid of ghosts." ”

"Oh," Hearing Tang Shishi say that he was not afraid, Li Yan said with a smile: "Since you are not afraid, then go quickly, we will wait for you in the courtyard." With that, he made a gesture and left.

Tang Shishi saw that Li Yan didn't accompany her, so she stomped her feet angrily and hummed: "Hmph, forget it if you don't accompany me." After speaking, Tang Shishi walked towards the location of Tang Liwen's room in a huff.

But as soon as he walked out two steps, Li Yan came to his side, Tang Shishi saw Li Yan next to him, and said unhappily: "Didn't you say that you won't go?" Didn't you wait for me with them in the yard? So what are you doing with me? ”

When Li Yan heard Tang Shishi's angry words, she knew that she was angry, so she said with a smile: "Hehe, I suddenly felt that it was boring to sit there, so I accompanied Sister Shishi to get the book, and I exercised after eating." ”

"Oh? Is it? Hearing Li Yan's words, Tang Shishi eased up a little and was not so angry, but she was still not very happy.

When Li Yan heard this question, he just smiled and didn't say anything. In this way, the two came silently all the way to the courtyard where Tang Liwen and Li Yushilai lived.
