Professor Chu was the east, and after dinner, Qin Luo did not forget the previous agreement with Professor Ji, and wanted to leave, but after thinking about it, he still went to the appointment.

After all, if you promise someone else's things, you have to do what you say.

"Qin Luo, I didn't expect you to really come. Professor Ji was very happy to see Qin Luo's arrival.

"Professor Ji, if you invite, how dare the kid not come. Qin Luo said politely.

"Don't call me Professor Ji, just call me Lao Ji. Professor Ji pretended to be angry and said.

"Let's call you Ji Lao. "How dare Qin Luo really call him 'Lao Ji', so he changed his name.

"Ji Lao, it's okay. Alas, you boy, what are you doing so politely?"

Although it was already evening at this time, Qin Luo still came to the history department by appointment.

Although Ji Lin seemed to have some old playboy personality, he was gladly invited, and Qin Luo had no reason not to go.

"By the way, Qin Luo, you held a class on what a gentleman is in the Chinese Department in the afternoon. Professor Ji asked.

"It's not a class, it's just a chat with everyone. Qin Luo said modestly.

"In that case, you will also give a class on what it means to be a gentleman in our history department in a moment. Professor Ji stated his purpose.

"Khan, Ji Lao, you want me to say it again. Qin Luo said speechlessly.

"Qin Luo, you little guy is so talented, are you embarrassed to repeat it?" Professor Ji teased.

"From this point of view, Ji Lao, you want me to give a more new explanation. ”

"Clever. ”

Professor Ji touched the beard of the little goat, and looked at Qin Luo with a smile.

"Ji Lao, you are giving me a problem. Qin Luo was speechless.

"What's the problem, don't you say that you are a great writer, what else can be difficult for you to be a great writer. Moreover, you have written so many words, and you have a lot of skills to fool, so you can fool the students of our history department again. Professor Ji said with a smile.

"Uh, Ji Lao, this is also called flickering. Qin Luo was really speechless about this old naughty Professor Ji.

"Isn't it. Let me tell you, in fact, I have been fooling others in class. Professor Ji touched his goatee and said.

"Okay. Qin Luo was defeated by this old playboy.

It was evening self-study time, and under Professor Ji's arrangement, Qin Luo came to a large lecture hall.

Hearing that Qin Luo was coming, a group of history students had already filled the large lecture hall.

"Ladies and gentlemen, good evening, I am Qin Luo, and I came to communicate with you at the invitation of Professor Ji. However, before the exchange, I have to say something to you, your Professor Ji is really amazing......" Standing on the podium, Qin Luo complained to Professor Ji a little.

And Professor Ji, who was sitting in the audience, didn't mind, and replied with Qin Luo's smiling face like an old naughty boy.

The rest of the students laughed.

"Qin Luo, we don't need to say this, we already knew about it. ”

"Hahaha, it seems that Qin Luo was also cheated by Professor Ji. ”

"Professor Ji is a living treasure of our Department of History. ”

"......" Qin Luo was speechless for a while, and then stopped grinding and started speaking directly.

"Some students may know that I gave a lecture on what is a gentleman in the Chinese Department in the afternoon. So now I'm going to talk to you about what a gentleman is. However, although I have shared this topic in the Department of Chinese, today I would like to talk about something different. ”

As soon as he flipped through the opening remarks, Qin Luo drew six horizontal lines on the blackboard and asked, "Does anyone know this pattern?"

"This is a trigram. As soon as he finished speaking, a boy with glasses stood up and said.

"Yes, that's the hexagram. ”

The six unbroken horizontal lines form a Qiangua, while the six broken lines in the middle form a kun hexagram.

Of course, Qin Luo is talking about Qiangua today.

"You must be very strange, what kind of gentleman am I talking about, and how did I start talking about gossip?" Pointing to this trigram on the blackboard, Qin Luo said.

"Let's sell it first, let's not talk about it for the time being, let's talk about this trigram first. However, before we talk about the trigrams, we must understand the eight trigrams. How to know it, he has certain rules. ”

Pointing to the blackboard, Qin Luo began to teach everyone to know gossip.

"As you can see, this hexagram is composed of six horizontal lines that are not broken, and these six horizontal lines are called yang yao (yao), and if there is a break in the middle, it is called yin. Therefore, we can see that the hexagram is composed of six yang lines. ”

"The three horizontal lines above are called the upper hexagram, and the three horizontal lines below are called the lower hexagram. ”

"In addition, we should also recognize the position, the odd number is yang, and the even number is yin. This means that the first of the six horizontal lines is the yang position, the second horizontal line is the yin position, and the third horizontal line is the yang position...... And so on. ”

"Yin and Yang gossip also abides by the principle that the same sex repels each other and the opposite sex attracts. Therefore, the yang and the yin attract each other, and the yang and the yang repel each other. ”

In addition, gossip also talks about the corresponding relationship. The first line corresponds to the fourth line, the second line corresponds to the fifth line, and the third line corresponds to the sixth line. ”

While drawing, Qin Luo introduced.

Although the gossip seems to be mysterious and mysterious, his structure is actually very simple, that is, it is composed of several yang lines and several yin lines, and the six yang lines are the Qiangua.

All the students are elites in the history department, and Qin Luo only explained these terms slightly, and everyone already knew it.

"To understand the hexagram, the first thing you need to understand is the words. What is a word? That is, the meaning of each of the six horizontal lines. The first horizontal line is written in the Book of Changes: On the ninth day of the first month, do not use the hidden dragon. Chu refers to the meaning of the first line, nine represents yang, and the meaning of the first nine is the first yang of the Qiangua. So who knows what it means not to use the hidden dragon?" Qin Luo threw out another question.

"Teacher Qin, don't use the hidden dragon means that the time has not come, and the gentleman must not act rashly. A slightly chubby boy immediately stood up and said.

"Very well answered. Qin Luo nodded at him appreciatively: "This is exactly what it means to use the hidden dragon. However, do some students know why the words of the ninth year of junior high school are written as hidden dragons and not used? Or how do we know that the time has not yet come, so we can't act rashly?"

If you talk about the previous few questions, many students know more or less.

Even if you haven't studied the Book of Changes, it's too famous for not using the word Qianlong, and many people know it.

However, when Qin Luo mentioned this question, the students couldn't answer it at all.

Not only could they not answer, but even some lecturers in the Department of History, including Professor Ji, could not answer.

Of course, it's not that they are not knowledgeable, but that they don't study it.

They live in the Hall of Elegance, although they also study the Book of Changes, but as Qin Luo said to Chu Chengjie before. These professors, these experts, or rather, these modern representatives of Confucianism, they only study righteousness. Whatever is written in the book, they explain it, or translate it, and they don't think about why this sentence is written on the I Ching.

In their opinion, this is what has been written in the I Ching a long time ago, and they only need to know what this sentence represents, and it doesn't matter why there is such a sentence.

It's just that I don't know, gossip is a match before this, and he doesn't have words.

And when there is a text, it is only after observing these conformities that the sage adds it.

Therefore, to explain this sentence, he cannot explain it from the sentence itself, and he has to observe the first line in the trigram.

That is, the ninth day of the first month.

"Students, it doesn't matter if you don't know, in fact, we can ignore this sentence for now, let's make a game of looking at pictures and guessing things. The ninth day of the first month is the first line in the Qiangua, simply put, it is the first horizontal line among the six horizontal lines. As you can see, from the whole hexagram, this line is at the bottom. It's a process of starting something from nothing, and it means that something has just started, or just emerged, and it hasn't grown yet. ”

"However, we can also see that there are five yang lines on it that have been pressing against it. It's like the six brothers, the other five brothers are all on top, and the ninth junior brother is at the bottom. As soon as the junior ninth brother has any movement below, the brothers above are definitely the first to know. Therefore, as a gentleman, at this time, he should know that it is best for me not to do anything now, and the smartest thing to do is to continue to accumulate strength. ”

"Therefore, on the ninth day of the first month, it is called the Hidden Dragon, Don't Use ......"
