Fu Lanqing thought about it, maybe he had misunderstood something.

So, he couldn't help but ask, "Teacher, what is perspective?" "Is it the perspective he understands?

"Perspective is also to see, and refers to the method or technique of depicting the spatial relationship of objects on a flat or curved surface."

Looking at Fu Lanqing, who was confused, Lu Jiu compassionately popularized the content of perspective for him.

The first study of perspective was the method of looking at the scenery through a transparent plane. Accurately depicting the scene on this plane becomes the perspective of the scene. Later, the science of using lines to show the spatial position, contours, and projections of objects on a flat surface according to certain principles is called perspective.

Lu Jiu asked Fu Yi to take out the glass, explained it to Fu Lanqing, and drew some perspective drawings by the way to help Fu Lanqing better understand what perspective is.

Fu Lanqing is very smart, almost a little thorough, and what Lu Jiu said is not very deep, so Fu Lanqing quickly mastered the principle of perspective.

All things are near big and far small, near high and far low, near real and far virtual, lines and lines are not parallel to form perspective, this is the basic principle of perspective, practice perspective from the cube, cuboid to start drawing, and then practice polygon, cylindrical, cone, etc.

Lu Jiu assigned Fu Lanqing homework, and planned to leave after collecting the class fee, but it happened that it was time for lunch, and Fu Lanqing left Lu Jiu a meal by the way.

During the meal, Fu Lanqing suddenly asked, "Do you still know how to read with Ah Yuan?" ”

Lu Jiu thought for a while and replied honestly: "After you reminded me like this, I realized that I hadn't been there for a long time, and I went to find Master Xu after eating." ”

Fu Lanqing can't wait to slap himself a few times, calling you cheap!

He instinctively didn't want Lu Jiu to have too deep contact with Ah Yuan.

It's a gut feeling, I just don't like it.

"Ah Yuan has been very busy lately, I'm afraid I don't have time to teach you." Fu Lanqing recommended himself in a serious manner: "It's better to do this, you teach me to sketch, and I teach you to recognize and write, how about it?" ”

Lu Jiu looked at him with a defensive expression: "Don't try to cheat me on the class fee!" ”

Fu Lanqing: "......"

A mouthful of old blood stalk is in the throat, not up or down.

Fu Lanqing let out a sigh: "The class fee is still paid, I will teach you to read and write for free, and I don't charge money!" ”

Lu Jiu looked at him suspiciously: "You have such a good heart?" ”

Fu Lanqing almost vomited blood: "You gave me porcelain that I have never seen before, and also provided me with snowy skin mooncakes for free, I don't want to owe you too much, so I plan to teach you to read and write, and repay your favor!" ”

Lu Jiu looked at him with some hesitation: "Do you know how to teach?" You won't mislead people's children, right? ”

Fu Lanqing: "...... "You are an illiterate person who teaches me to draw, I don't think you are misleading, why do you think that I, who is full of wealth, can let the head of the academy give me a great talent and mislead the child of the old man who studies ink?"

He didn't want to say much, and directly left a sentence: "It's free, do you want it?" ”

"Yes." Just when Fu Lanqing breathed a sigh of relief, he heard a certain woman muttering in a low voice: "There is a bargain that is not a bastard, not to mention that it is a bargain that is automatically delivered to the door, and I have earned it!" ”

Fu Lanqing put down the jade chopstick, turned around and left.

Lu Jiu gulped down the meal and asked vaguely, "You don't eat it?" ”

"No more!" The gas makes you full!

It's just right not to eat, these dishes are mine~

Lu Jiu smiled and squinted, the cook of the Fu family was so delicious, it was even better than what the chef of Baiweilou cooked.
