On the blackboard, Professor Yi drew a pattern that looked like a candle in red chalk. In the middle is a standard rectangle, with a thin line extending from the top and bottom, and the length looks arbitrary.

Then the professor took his slender bamboo whip and tapped on the blackboard.

"This pattern is the basic component of the diagram, the diagram. ”

"The top point," the professor said, pointing to the top of the shadow on the candlestick chart, "refers to the best thing that happens in the day, and the bottom point refers to the worst thing that happens in the day." ”

With the whip's point, two cloud-like interpretive patterns appear next to the upper and lower shadows, marking their respective meanings. Then the whip moved to the lower edge of the rectangle:

"The following line is the time you get up, and it is also an 'eye-opening line' for your overall state after you open your eyes. ”

Correspondingly, the above line is the 'closed eye line' when you lie in bed and fall asleep with your eyes closed. ”

"The four dimensions of opening the eyeline, closing the eyeline, the best thing, and the worst thing constitute a complete and independent line chart. ”

"Now the line chart on the blackboard is red, which means that when you open your eyes in the morning, you may have encountered something bad, but from that bad point, your fortune rises until the best thing of the day happens, and then it slowly calms down and you can sleep peacefully. ”

"There are very few people who wake up in the morning and have been smooth sailing throughout the day, and good things continue to go straight to sleep until they go to bed at night...... But just because there is little does not mean that there are no ...... In this case, the two poles representing the 'best thing' and the 'worst thing' are covered by the 'eye-open' and 'eye-closed', which soothsayers call the 'bald head and bare feet yang line'. ”

"The yang line, which is the red line, means good luck throughout the day. ”

"If there is a positive line, there will naturally be a negative line. ”

"The yin candle is different from the yang candlestick, and we use green to indicate it. ”

As he spoke, Professor Yi's bamboo whip struck heavily on the blackboard, and the 'eye-closing line' of the original red line diagram slid all the way down as if he had taken an elevator, until it slid for a while after crossing the 'eye-opening line', and then slowly stopped.

At the same time, the previously red thread slowly changed from red to orange, to yellow, and finally to green.

The professor's voice rang out at the right time: "If you get up and soon after you open your eyes, you encounter a little bit of good things, and then all day long, bad things keep happening, and your fortune does not get a little better until the evening, then this is the line chart you got that day." ”

"Similar to the 'bald head and bare feet yang line', there is also a 'bald head and bare feet yin line' in the line diagram...... This long black candle means that you have not encountered any good things throughout the day, from the time you open your eyes to the time you close them at night, and you may have insomnia when you sleep at night. ”

Hearing the professor's explanation, there was a sigh of concern in the hall, as if everyone had such a bad experience. Zheng Qing didn't have time to sigh with the others, he held one hand to his chest, pinched his chin with the other, and was looking thoughtfully at the huge green thread on the blackboard, always feeling that the pattern on it seemed familiar.

Professor Yi struck the whip in his hand viciously again, and the classroom that had just made waves was calm.

"Something like that!" he raised his voice slightly, and the line diagram on the blackboard disappeared in an instant, and then a series of bold and weighted white chalk words appeared on the blackboard:

"Similar! Depending on the daily fortune, the line chart will have different meanings!"

"For example, when you are sleeping almost all day, and your eyes are very close to your eyes closed, and the 'best thing' is not much better than sleeping, there will be a red cross-shaped line chart, which we call the 'little yang star'. ”

"And so on, there are 'small yin stars', 'hanging yang lines', 'lower shadow yang lines', 'big yang lines', 'piercing head and broken feet yang lines', 'bare feet yang lines' and so on............ What are you waiting for? Why don't you copy these concepts down?!!"

With Professor Yi's slightly annoyed voice, the students who were originally staring at the blackboard lowered their heads almost at the same time, and in an instant, a rustling sound sounded in the classroom almost at the same time, as if the hungry spring silkworms were gnawing on mulberry leaves.

Professor Yi obviously enjoyed this kind of background sound, so his tone became much softer:

"In reality, our lives are made up of minutes and seconds of time and experience, and when this process is digitized, it becomes a line chart. ”

"We always have expectations of one kind or another in life, and these expectations will always be influenced by the environment around us. ”

"Sometimes expectations are high but low in realization, and sometimes expectations are too low and the reality is divergent...... All of these things are reflected in the line chart. ”

"Stitching together the line diagram of each day constitutes a zigzag curve, which I call the 'life line', and our lives can actually be simplified into such a line. ”

"Our mood is either positive and optimistic every day, or negative and pessimistic, and our experience is either cheerful and happy, or sad and lost, no matter how it changes, our lives are up and down around this seemingly fixed thin line, but in fact we are left and right. ”

"How to read this thin line, how to draw intervals and trends through this thin line, is what we will learn in the next few lessons. ”

"Now, after copying the concepts on the blackboard, please open your 'weekly notebook', and then come to the podium and receive a 'World Wide Grid Paper'...... The rest of your lesson, as well as your homework for this lesson, is to make a line chart of your experiences every week from the beginning of school to the present. ”

"The spells you need to digitize the diagram are not difficult for you to use in the appendix chart of the textbook, so I won't go into details...... If you really don't understand something, you can consult me separately after class. ”

"Here, I would like to reveal to you one thing in advance, that is, in the final divination exam, there must be a big question related to 'trend divination'. If you lay a good foundation in the initial learning process - for example, when you make a line chart, you will be accurate to the day instead of the week - then it will be very helpful for your subsequent learning, especially to accurately predict future trends. ”

This is the end of Professor Yi's lecture.

After a moment of silence in the classroom, there was a creaking noise of desks and chairs moving, and the students lined up quietly and sadly to the podium to receive the large sheet of paper, covered with a fine grid.
