This is a hand-drawn lesson.

The instructor of the class, Mr. Li, who is in his 40s, spoke very seriously, clearly organized and the steps were clear. In addition to using electronic PPT presentation courseware to assist the explanation, he also hand-animates some neat and detailed basic geometric figures on the blackboard from time to time.

The classroom was quiet, and the students seemed to be listening attentively. But a closer look reveals that something is not quite right.

Mr. Li is just singing a one-man show. Many of the students below are simply apes and horses, and they are in Cao Ying, and their hearts are in Han. Some are looking at other books by themselves, some are looking left and right blankly, some are squinting and half dozing, and some are even peeking at their mobile phones under their desks.

Hand drawing is not a compulsory course this semester, it is just an examination course, no wonder many students do not pay attention to it.

Another reason for such neglect of this course may be that many students think that this course is no longer of much use and is outdated.

Today's computer technology is so developed, the construction industry is basically all computer drawing, who still engages in manual drawing?!

THE FRESHMEN ARE STUDYING AT THE SAME TIME THIS SEMESTER, THERE ARE AUTOCAD, PHOTOSHOP COMPUTER GRAPHIC DRAWING COURSES AND 3DMARK STEREOSCOPIC DRAWING COURSES, WHICH ARE COMPULSORY COURSES. Many students think that this is an important tool for basic drawing.

Looking at the casual listening mood of a large number of students in the classroom, Mr. Li suddenly stopped lecturing.

The stunned sound of the lecture alarmed many students below. They all looked up at the instructor on the podium in bewilderment.

Teacher Li didn't say anything, just turned around and silently wiped the blackboard, erasing all the content on it. Then, he quickly wrote a famous sentence:

"Withered vines and old trees, faint crows, small bridges and flowing water, ancient roads and west wind thin horses. The sun is setting, and the heartbroken man is at the end of the world. ”

Yao Yayao, who was in a corner below, looked at this sentence with interest. It's an old song he's always loved. It's not just a poem, it's even a painting. There is nothing more vivid and expressive than this sentence that can automatically generate a picture in the reader's mind with a few words.

With a piece of white chalk in his hand, Mr. Li began to draw by hand at the bottom of this sentence.

The first thing that appeared was two cliffs standing opposite each other, and then the river below the cliffs, a big tree, the sunset, vines, a flock of crows, a small house on the post road, a horse, a lonely figure on horseback, and so on.

All the small scene items are very three-dimensional, almost trying to break through the blackboard and rush towards them. Every detail is incomparably fine, and it's too beautiful to be true. This is definitely a masterful Chinese painting masterpiece!

There are already many students below who are applauding.

It seemed that the whole picture had been completed, and then Mr. Li turned around with a smile on his face.

The applause continued. But there are also sharp-eyed students who have discovered something, and some students can't help but remind them loudly:

"There is no bridge! Poor bridge! There should be a small bridge between the two cliffs! ”

"Teacher, let's have a small bridge!"

"Oh! Is it?! Teacher Li turned around again. He didn't immediately draw the bridge, but picked up the blackboard and erased the short sentence completely.

The classmates were a little confused and didn't understand why he erased this sentence. Then, the unthinkable happened.

In an unusually neat, angular and special handwriting, Mr. Li re-wrote this sentence in the middle of the two cliffs on the blackboard.

There is no punctuation, just twenty-eight characters that resemble a printed type. Every word is decent and square. The spacing between words is exactly the same. Each character is a delicate and upright long body, and the strokes are horizontal and vertical and evenly thick. They are beautiful and neat, clear and beautiful, strong and powerful, and the whole arrangement is extremely harmonious.

This sentence makes a beautiful horizontal bridge between the two cliffs. It looks like a stone bridge with all its edges on the horizon.

There is no sense of disobedience at all on the whole picture.

Anyone who looks at it will see that the whole picture is a beautiful painting. However, on closer inspection, the bridge is made up of a single line of text.

The students in the classroom all know the traditional story of "Queqiao Meeting". But the one who can turn the square text into flesh and bones, and build a small bridge in the blink of an eye, has really never seen it.

After Mr. Li showed such a masterpiece, the classroom had already resounded with thunderous applause. Many students took out their mobile phones and took pictures of the painting.

Teacher Li raised his hand to signal the excited students to calm down.

"This font is a common imitation of Song style on architectural drawings. When I was in college, any student had to practice this font by hand for at least a year before they could succeed. Those who can't write this font are embarrassed to say that they are civil engineering students. ”

"Back then, we relied mainly on hand drawing. Sometimes, you can't draw one in a day. Before the drawings can be published, they need to be traced on a translucent piece of special paper. Often, if a drop of ink is accidentally dropped in the middle of the way, the hard work of more than ten hours a day will be in vain! ”

"Nowadays, computer technology is developed, and architectural drawings are all computer drawings! The old artisanal techniques are obsolete and obsolete! However, that doesn't mean that hand-drawn drawings won't matter anymore! ”

Teacher Li on the tutor's podium, speaking in a very slow voice. His eyes were blank, and there seemed to be a hint of immersion in old memories of his student days.

"Architectural engineers can't always stay in a big city greenhouse with a computer. In the future, you will set foot in any remote mountain and river in the motherland to engage in construction. If there is no computer as a medium, especially in some places where there is no electricity, how can you use drawings to communicate with your peers face-to-face? ”

"If you don't know even the basics of manual drawing, how can you draw the details of the construction drawings on the spot? Do you have to wait for the plane to come from the rear by air to express the computer drawings? ? ”

Teacher Li's voice began to become stern. Many of the students below bowed their heads and were speechless, and all of them were silent.

"I will not give any more lectures below, but I will show you all the hand-drawn style of ancient buildings of famous masters of architecture in my country. Compared to the late master, my drawing skills are not even an ant. ”

"If you can't grasp some of the historical essence of architecture from his hand-drawn drawings! I can only say one last thing: none of you here deserve to be students of architecture!! ”

Teacher Li seemed to be a little excited. He ended up opening a slide presentation on his computer console and walked out of the classroom.

The huge electronic screen on the instructor's podium began to appear one after another handmade fine architectural drawings. They're slowly circulating and rolling.

Each pair is incredibly delicate and exquisite, so full of artistic charm.

"Oh my God! It is a hand-drawn sketch of Liang Sicheng! ”

"He founded the Department of Architecture of Qinghua University! Oh, my God! That's beautiful, isn't it? ”

"O Master! An absolute national treasure master! ”

"Those lines are simply ingenious! The computer drew only dead objects, and the drawings seemed to be alive. ”

Many of the students below were amazed by these handmade drawings. There were many people with envious looks on their faces. There are also people with a look of shame on their faces. More of them are staring intently, with a thoughtful look on their faces.

Yao Yayao, who was in a corner, frowned into a deep "Sichuan" character. He was also staring intently at the slide show above.

Yao Yayao had a blank notebook in his hand. Above, there is a copy of the painting he just made on the blackboard of the podium. The overall picture is actually six or seven percent like a god, which is a bit similar. However, the small bridge of words in the middle, he had to leave it completely blank. With such a delicate and square text, he couldn't copy it at all.

Yao Yayao used to be very fond of graffiti when he was in junior high and high school, but he didn't have much time to develop his personal interests freely. However, under the personal fumbling, there is still a little foundation.

In the afternoon of the same day, Yao Yayao signed up for a student painting club at the school, focusing on black and white still life sketching.

That night, on Yao Yayao's personal desk in dormitory 216, there were a few more hard-pen calligraphy notebooks. Among them, there is a special copy book that imitates the Song font.
