The footsteps are clicking, and the wheels are rattling.

This is a narrow old street, but after meticulous care and decoration, it has swept away the decadence of the past and turned into a cultural and creative street with a sense of age and literary atmosphere. Literary and artistic youths from all over the world gather here, order a cup of tea and spread out a book, read and chat, and will not disperse until late at night.

Looking at the small but creative light signs on both sides, the round-faced girl had an expression of joy and surprise on her face.

After the dinner, she and Zhang Xuyao left the hotel to wander around, and then they were led through the streets and alleys to discover a new world.

"King, you are really tired, this place is so hidden, you can find it!"

"Of course!" Zhang Xuyao in the wheelchair also had a full face, "I have lived in Ludao for so many years, and when I have a weekend break, I will wander around, where there is delicious food, fun and good-looking, I can't escape my eyes!"

"Well, it's good to be a teacher, I don't work overtime on weekends and winter and summer vacations," Mao Mao casually envied, but her eyes fell on the cat-shaped signboard not far away and couldn't take it off, which was a cat coffee shop.

High-rise residents are inconvenient to raise pets, and animal-themed coffee shops that cater to the needs of animals have begun to emerge in large numbers around the world.

Although in the name of the cat, this girl is just a "cloud cat slave" who is active on the Internet, after all, the company she used to work for worked overtime frequently but was not allowed to bring pets to work, so it was naturally difficult to invite a master to go home and be confined. Seeing a cat café infested by a cat uncle right now, it's hard to resist.

The wheelchair suddenly stopped moving, Zhang Xuyao looked left and right and quickly understood the reason, and said with a smile: "I know that you will definitely not be able to move your legs when you see the cat café, let's go and sit down!"

"Uh-huh!" Cat nodded decisively, and quickened her pace to push the wheelchair into the small shop.

The coffee shop is a converted private house, only about a dozen square meters, but it is quite delicately arranged. At the entrance, there is a washbasin and a bar, on which coffee equipment is placed, and on the display shelves next to it are small items such as cat dolls and colored porcelain water cups, and the style does not look like the big road goods that can be seen everywhere.

In the middle of the shop are large climbing frames and six or seven cat beds, but the human seats are a circle of low stools and cushions on the wall, which fully reflect each other's status.

Of course, the difference in status is only a superficial article, no matter how big the climbing frame is, no matter how good the cat nest is, it can't change the fact that this is a place for cats to pick up customers and people to consume. In order to better serve customers, Cat Cafe usually chooses adult cats over 3 years old, different breeds, and docile and friendly temperaments, many of which have been castrated to avoid crossbreeding.

In the eyes of some cat lovers, these behaviors that violate the nature of cats are heinous and drink cat blood, so they almost shout "Eliminate human tyranny, the world belongs to cats". However, they are only a minority, and the "employee labor protection" of regular cat cafes is guaranteed, and ordinary cat slaves are unable to resist the attraction of cat coffee, such as these two girls now.

This store also has "labor protection" measures, before entering the door, the owner reminded them to wash their hands and disinfect, and pointed to the small blackboard, so that the two of them can see the five store rules above: first-class cats come by themselves, two do not touch, three do not disturb sleep, four annoyance, please whisper, do not turn on the flash.

Although the rules are quite big, the two girls still accepted it happily, sorted it out, ordered coffee and snacks, and handed the light gray plate with dried small fish to Zhang Xuyao to hold, pushed the wheelchair inside, stepped on the brake and sat on the opposite side.

It was rare to see a girl in a wheelchair, and soon a gray-blue Ying short walked over with a tail and a catwalk, raising his head to look at Zhang Xuyao. The uncle took the initiative to come to the door, and the latter happily bent down and stretched out his hand, but was flexibly avoided by the other party and walked away with a look of disgust.

"Haha!" The girl on the other side laughed happily, shaking the phone in her hand proudly, she had been scared of the scene just now. Because of the sound of closing the shutter and flashing, Mr. Zhang and the cat didn't notice it, and dedicated a performance with no acting skills.

"What are you laughing at?" glared at his friend, "The cat owner is like this, only she is allowed to post upside down, not you." ”

It seemed to be annotating her words, and soon another white-haired and gray-faced puppet came over, jumped decisively on the small table, and then jumped on top of the wheelchair, and lay on Zhang Xuyao's lap in a small circle, the big gray tail shook and screamed lightly twice, as if to say, "Human, you can start massaging." ”

This time it shouldn't be wrong, Zhang Xuyao hurriedly used the cat petting skills she learned from the bee brand robot cat, and served the temporary master.

Fingers slid in the clean and smooth white hair of the Ragdoll, and she didn't forget to raise her head and throw out a provocative expression, so angry that the cat wanted to stand up and throw her a sentence of "Friends don't give it away!"

Fortunately, the shopkeeper arrived just in time to save the friendship boat that was about to capsize.

Squatting down and putting the coffee snack on the small table, the shopkeeper looked up at the white cat in Zhang Xu Yao's arms.

The latter hurriedly explained, "She jumped up by herself, shouldn't it be against the rules of the store?"

"Of course not," the shopkeeper smiled gently, "Duoduo likes to play with customers, so it didn't bother you, did he?"

"No, no, I like it!"

"That's good," the shopkeeper reminded, looking at the small dried fish in her hand, "if you take it like this, she won't eat it, you have to put it aside, and if they are hungry, they will eat it themselves." ”

With a few polite words, the shopkeeper got up and left. The cat couldn't wait to put the small dish on the floor, and then looked at the puppet in Tang Jiayi's arms with burning eyes.

Unfortunately, there was no use for the eggs, and the cat seemed to have been fed for a long time, and it didn't even take a look down. In the end, the black cat on the opposite shelf got off the ground flexibly, trotted over and quickly took a piece of dried fish and walked away with the cat, without stopping the whole process, without giving humans the slightest chance to touch him, and the cat was stunned and speechless.

"Hehe!" Seeing everything in his eyes, Zhang Xuyao couldn't help but chuckle.

However, she soon became very happy, and seemed to be dissatisfied with her massage skills, and the puppet named Duoduo in her arms bent her legs and jumped off, and ran back to her cat nest without hesitation.

"Hahaha!" Finally waiting for the opportunity, of course the cat will laugh back. Although the voice is not loud, the expression and posture are extremely exaggerated, and Teacher Zhang is angry for a while, "Shen Xiaoni, I want to break off my friendship with you!"

The round-faced girl whose real name is Shen Xueni smiled and put on a shy expression: "I don't have an opinion, but is it right here?"

was teased with a homophonic stalk, Zhang Xuyao was so angry that she panted, raised her head and blew her air bangs, she picked up her mobile phone, "Forget it, I don't have the same knowledge as you." ”

According to international practice, she took pictures of the store layout and the Italian latte with cat's head latte art in front of her, and then she took a sip of the cup, and the temperature was just right. Although it is only machine brewed, the taste is quite delicious, and the bitterness of the coffee is masked by the rich milky aroma, which becomes smooth and sweet, and the mouth is full of lusciousness.

Putting down the cup, she knocked on the white cardboard box placed next to her, and asked the other party with a smile: "You're not curious at all, what is in here?"

In front of each of them was a powder blue box, about the size of a keyboard box, which was a souvenir from the Bee Group to the guests at the banquet.

"What else can there be?" Shen Xueni pouted, "It's nothing more than wireless chargers, Bluetooth speakers, mobile phone cases, power banks, video sticks and other peripheral products, which are worth between 200 and 300." Hey, I was once given a set of tempered film sets, and I was forced to get 200 yuan, which made me unwanted. ”

"Okay, this is really the usual style of bees," Zhang Xuyao sighed slightly, "I have also received a lot, and there is never a shortage of USB flash drives and flashlights at home." ”

Picking up the blue box and checking it, the cat estimated and said, "It's quite big but it doesn't weigh much, it should be something like a keyboard holster." Of course, it could also be the flat tempered film set ......"

"You have a really big grudge against the tempered film," Zhang Xuyao complained casually, she didn't know what was inside, picked up her box, "Open it and see if you know!"

Loosen the bow and open the gift paper, revealing a white box with cute stick figures scattered on it, which looks quite childlike.

Nodding slightly, she said casually: "You can rest assured, it doesn't look like a tempered film, and it doesn't look like a keyboard sleeve." ”

Remove the lid of the box, the answer is officially revealed, a black tablet appeared in her hand, the side is thin wedge-shaped, the front rectangle is similar to a 7-inch tablet, most of the front is occupied by the screen, but the color is a little wrong, not the dark gray and nearly black when the LCD screen is turned off, but the light gray is somewhat similar to the e-ink screen.

"Huh?" Shen Xueni exclaimed, "It's actually an e-book reader, it's not like a bee's style!"

The reader is not very cheap, even the beggar version of the Kindle with Amazon subsidies costs 558, and the price of other domestic products is a little higher. Bee's e-paper book reader "Color Reading" is equipped with a color butterfly screen, and the price is more than 2600 yuan.

"Think beautiful!" Seeing the actual appearance, Zhang Xuyao already recognized it, "This is the bee's 'cloud note' electromagnetic handwriting tablet." ”

"Writing board?" Shen Xueni was immediately a little disappointed, "I have a colleague who bought this thing, although it is cheap and energy-saving, but it is not very convenient to use, the green characters on a black background are only suitable for writing, and it will look very strange when used to draw." And it can only be completely erased, not smeared and modified, and a full page has to be photographed and saved with a mobile phone, and he used it to press instant noodles after playing for a few days. ”

Stretching out his index finger and tapping the board on his knee, Zhang Xuyao said with a smile: "Dear, what you said is another small LCD blackboard, this is an electromagnetic small whiteboard developed by bees, the actual technical principles are not completely consistent, and the functions are very different." ”

The small LCD blackboard in her mouth is a new product that has only appeared in recent years, based on pressure-sensitive bistable liquid crystal display technology.

Bistable liquid crystals can maintain a translucent or opaque state for a long time, and can transform into another state when disturbed by external energy, which is regarded as a good material for manufacturing ultra-low-power display devices. Pressure-sensitive liquid crystal is sensitive to pressure, with a hard pen tip or even a fingernail on it, you can disturb the local liquid crystal molecular arrangement, so that it changes from transparent to opaque to show white green handwriting, as long as a black bottom plate is placed under the liquid crystal and a thin film circuit used to reset the liquid crystal, you can make an LCD blackboard that supports pressure handwriting.

Because no energy is required to display handwriting, the LCD blackboard consumes very little energy, and a single coin cell battery can support tens of thousands of erase operations. Coupled with the simple structure, the cost of this small blackboard is very low, about 7 inches of domestic brands as low as sixty or seventy yuan, and the same foreign style does not exceed 300 yuan, cheap and affordable is very popular for a while.

However, as Shen Xueni said, this kind of product can only be made into a blackboard because of the white color of the handwriting, and it cannot be partially erased but can only be cleaned globally, and if you want to record and save your handwriting, you need to install additional electromagnetic touch screens, storage units, processing chips, and wired/wireless data interfaces, which leads to soaring costs, and all kinds of shortcomings limit its further application.

The Bee Whiteboard is also based on bistable liquid crystals, but it is an electrically driven type. The black and white switching of the picture is all realized through the thin film circuit, and the perception of the brush stroke is through the electromagnetic touch screen and stylus, and the display principle is more similar to the traditional liquid crystal display, and the white background and black background support handwriting erasure, saving and exporting. However, correspondingly, the energy consumption and cost are also much higher than those of the small blackboard.

"I see," Shen Xueni became interested, lowered her head to open her box, and took out an identical tablet.

Looking down, she first noticed the difference in appearance, "Well, the workmanship is indeed a lot more exquisite, the screen is not concave, the bezel is quite narrow, and this pen is also good." ”

"Of course, Bee is also a professional tablet manufacturer, and its design capabilities and mold accuracy are not comparable to ordinary small factories. ”

"I'll try it first," the girl on the other side nodded slightly, pressed the button to turn on, picked up the stylus and drew a black arc on the screen, and added a few more strokes to form a round-faced glasses cat.

"It feels okay, it looks more pleasing to the eye than the green words on a black background, but the contrast is still a little low, and it's not very handy. ”

This is something that can't be helped, the small blackboard is a liquid crystal molecule directly under pressure and discoloration to show handwriting, but the small whiteboard has to be driven by electromagnetic positioning, pressure recognition, and circuits to produce handwriting of different thicknesses, and the response speed is slower. Fortunately, the average person can't move the pen like a fly, and considering the "eraser" and undo function brought by the new model, the problem of unresponsiveness is not unbearable.

The only problem is the cost, taking a breath, Shen Xueni hesitated: "How do you feel that this thing is a little high." The price and battery life are not as good as the LCD blackboard, the color is not as good as the SurfacePro and iPadPro, and the recognition accuracy is not as good as A. If I'm not mistaken, it seems that the cheapest professional hand-drawn tablet is only over 500. ”

"Dear, let me change the order for you," Zhang Xuyao smiled and stretched out three fingers, "Bluetooth is connected to a mobile phone, it is more convenient to use than an LCD blackboard; the price is not more than a thousand, it is cheaper than Sophie's mother-in-law; there is no need to connect to a computer, it is more intuitive and convenient than a hand-drawn tablet, doesn't it feel better?"

"It seems so, but why did the bees suddenly become interested in this piece?"

"You'll know tomorrow. ”
