The students felt that the time in Professor Qi's class passed quickly, just because they were very interested in the topics that Qi Jiaoyao said.

Seriously, is there a modern college student who doesn't have the slightest interest in historical stories? Although they still don't understand the use of studying history and why the state has not abolished this seemingly useless subject for so many years, it is also a good thing to occasionally take history classes and listen to historical events as stories to relieve boredom during their boring academic career.

"After class, there is a twenty-minute break, Brother Feng, do you want to go to the toilet?" Now the whole class doesn't treat Wang Ke as a man, just because of the things like inviting the same sex to go to the toilet together, in the hearts of the boys, generally only girls will do, boys are very small, maybe Wang Ke is the first in the history of Yenching University.

"It's gone!" Qin Yifeng sat alone on a chair and refused Wang Ke's invitation without raising his head, and then Wang Ke went to the toilet with a group of girl "sisters".

"I really don't know, but will my sister go into the men's or women's toilet later?" Kemei is the nickname that the classmates called Wang Ke, and Wang Ke doesn't seem to be too disgusted by this title.

Some students were a little envious when they saw Wang Ke leaving with the girls.

"Be quiet!" Qin Yifeng suddenly opened his mouth and said to the boys who spoke, his eyes were a little solemn.

"What's wrong, Brother Feng?" The boys saw that Qin Yifeng was looking at the book on architectural history very seriously, and the more they looked at it, the more solemn their faces became.

"It's okay, you guys just don't talk quietly and don't disturb me!" Qin Yifeng sent everyone away, and then continued to look down at the book, the more he looked at it, the more strange his face became.

I saw that the chapter that Qin Yifeng read is about the architectural style of the Qin Dynasty in ancient China, the book says that when the family of the Qin Dynasty built a mansion, they would engrave the symbol representing their family in front of the gate, and just now, a picture that Qin Yifeng saw was a real photo of an ancient house during the Qin Dynasty, and there was a dragon-shaped symbol carving on the door of the ancient house, which made Qin Yifeng feel very familiar.

Qin Yifeng squinted his eyes and slowly recalled in his mind, where did he see this dragon-shaped carving?

"Iron box?"

Yes, the iron box sent to him by Qin Yifeng's three masters carved a dragon head pattern, and the shape of the dragon head is very similar to the dragon head of this dragon, do his parents have anything to do with this dragon carving?

"This classmate, why don't you go and do some activities?"

A morning class is also Professor Qi's class, not only do students need to rest during the break, but Professor Qi also needs to relax, but when he walked around outside and returned to the classroom, and found Qin Yifeng looking down at the book, he couldn't help but feel curious, this student is too hardworking, like him, such a high-intensity and high-pressure learning effect will not be good! Professor Qi was a little worried.

Qin Yifeng looked up and saw Professor Qi looking at him with a smile on his face: "Why don't you go out for an activity, long-term high-intensity study is not beneficial to the body!" ”

"Thank you for your concern!" Qin Yifeng now seems to have a lot of respect for Professor Qi, just because he knows that Professor Qi is a capable person, and what he respects most in his life is this kind of person with real materials.

"What are you looking at?" Seeing that Qin Yifeng just looked up at himself for a moment, Professor Qi couldn't help but be interested, "Oh, the architectural style of the Qin Dynasty, are you interested in this chapter?" ”

"Hmm!" Qin Yifeng nodded immediately, and he suddenly thought, isn't there a historian in front of him? Won't he be able to answer the questions in his heart?

"Why are you so interested in the architecture of the Qin Dynasty, and are you also interested in the history of the Qin Dynasty?" Professor Qi asked, and when it came to historical knowledge, Professor Qi seemed a little interested.

"This ......" Qin Yifeng thought for a moment, and then said: "I don't know much about history, I only know that there was a Qin Shi Huang in the Qin Dynasty, and it was Qin Shi Huang who unified China. Qin Yifeng had a feeling that his iron box was not simple, so he subconsciously didn't ask Professor Qi about the dragon head pattern of the iron box: "By the way, Teacher Qi, I don't understand much here." ”

"Oh?" Professor Qi looked at the book and asked, "What don't you understand?" ”

"Here, I don't understand why the big family of the Qin Dynasty wants to engrave the symbol representing their own family on the door!" Qin Yifeng began to pull the topic to the carving on the door, pointing to the book and asking......

"That's right!" Professor Qi also felt that Qin Yifeng seemed to be hiding something, but for a student who loves to learn, he didn't think too much: "The class concept in the Qin Dynasty was very heavy, and the bigger the family, the more admired people would be, so those families in the Qin Dynasty would engrave the symbols representing their own families on the door to show the dignity of their families." ”

"Oh, I see!" Qin Yifeng smiled, revealing an expression of understanding, "Usually only big families engrave symbols on the door?" ”

"No, as long as it is a family, they will engrave the symbols representing their family on the door," Professor Qi said: "In order to show the dignity of their family, those families not only engrave the symbols representing the family on the door, but also paint the family symbols on the clothes of the clansmen, but the colors used are different, by the way, these have nothing to do with the history of architecture, do you still want to listen?" ”

"Yes, my favorite thing is to listen to historical allusions!" Qin Yifeng responded as if he was very interested, which made Professor Qi very happy, Qin Yifeng vaguely remembered that the dragon head pattern of his iron box seemed to be white.

"Yes, first of all, let's talk about yellow, this yellow is the exclusive color of the royal family, so except for the royal family, all families cannot use it, and the rest of the big families will use different colors to paint symbols representing their families on their clothes according to their status."

"What color will they use?" The more Qin Yifeng listened, the more nervous he became, this was probably related to the history of his ancestors, could he not be concerned? Qin Yifeng was very glad that he didn't leave before class, otherwise the clue to find his parents would be broken.

"You've heard of Wang Jian and Li Si!" Professor Qi asked, and when he asked this, he suddenly remembered that Qin Yifeng had just said to himself that he was not very familiar with history: "Wang Jian and Li Si are the most powerful courtiers of Qin Shi Huang, so the color of their family symbols is the same as the armor of the Qin Dynasty army, which is black, and under the two of them, according to their status, they use gold, silver, red, blue, green, and gray six colors." ”

"Is there only a few colors??" Qin Yifeng listened to it for a long time, but he couldn't hear the white symbol, which made him feel very strange: "In addition to these colors, are there any other colors?" ”

"No more!" Professor Qi thought for a moment, and then spoke.

"Looks like the clue is broken again!" When Qin Yifeng heard Professor Qi's answer, he couldn't help but feel a little disappointed when he knew that the clue had been broken again.

"Wait!" At this moment, Professor Qi seemed to suddenly think of something, "It seems that there is another color, but the family that uses that color is very special. ”

"What family?" Qin Yifeng saw that the clue was not broken, so he immediately became excited and asked Professor Qi.

"I've seen this in ancient books, but I haven't mentioned what it is, and I don't know very well, so I can't answer you!" Professor Qi's face was a little red, obviously dumbfounded by a student's question, and the inability to answer the answer was something that he felt very embarrassed, "Well, if you are really interested, come with me to my house after school, and I will lend you that book!" ”

"Thank you, Professor Qi." Qin Yifeng saw that Professor Qi couldn't answer his question, and he didn't bother anymore, he just wanted to get the ancient book with Professor Qi after school quickly and see if he could find a clue, but obviously, this chance was very slim.

"Alright, class!" Professor Qi looked at his watch and said, then walked to the teaching altar to prepare for class, still thinking about the question that Qin Yifeng asked that he couldn't answer, and when he thought of Qin Yifeng, he found that he liked this hardworking young man a little......
