"Optical scanning systems aren't just for publishers. It was the plants that first proposed the establishment of this system. The Display Research Institute of the Institute of Computer Science has developed a miniature glasses-type display and an optical camera, scanning and identification system. Originally, it was mainly used for the junior students of the Institute of Vegetation to learn and identify plants in the field, and it had a plant database search function. ”

What the researcher showed Zhang Chun was a retractable glasses monitor that was combined with a helmet.

"The accuracy of this display is already very high, this is a student field model, and the medical school has banned the installation of too many electronic devices, including radio equipment, on the helmet. So there is only one memory with plant information and a microprocessor. It tracks and shoots the plants with this miniature high-definition camera and retrieves them through a pattern recognition system. At present, there is only this function, which is a simple school supplies for primary and secondary school students. ”

Because the model is small for Zhang Chun and big for Niuniu, everyone can't use it. But being able to see some faint light sliding on the glasses is a simple graphic and textual simplicity. The display light is so faint that it is impossible to detect it without paying attention.

"Although it looks like the light is very low, because it is close to the eyes, the wearer can see it very clearly. At the same time, it also has a great impact on the eyes. There is a button to adjust the brightness and contrast, but this design is rejected by medical schools, who believe that people should not focus too much on the visual range that they feel comfortable with, which will not only not help people, but will limit people's vision to a narrow range, causing local visual fatigue. Eventually, it leads to vision loss. The cause of nearsightedness or farsightedness may be due to this. The medical school believes that light should be based on a standard that does not affect visual fatigue. At the same time it is believed that such devices can only be used in schoolchildren, because of the properties of plants, in addition to the shape. There is also the identification of aromas, tastes, and touches, and to understand the properties of plants, you must touch and taste them in person. The same plant, because of the different environment, some have medicinal effects, some have no medicinal effects, and some are mixed with other medicinal effects. This is not something that can be written clearly in any book, and it is necessary to develop students' discernment skills from middle school. A letter is better than no book. ”

"Yes. Medical school is right. Zhang Chun affirmed the medical school's statement. But it's a good idea for the dissemination of knowledge in the natural sciences, which always accompanies what we observe. This is still very useful in the early stages of learning. It also seems good for reading the classics. You just can't rely too much on it. In the wild, human judgment is crucial. If you don't look and judge carefully because of the letter. It would be a fatal mistake".

Zhang Chun hesitated for a moment and said: "There may be another argument in the world, that is, only the things that have been observed and familiar by the predecessors are left, and everything that is unfamiliar and unknown is destroyed to ensure their so-called authority." It's not about letting nature evolve and evolve, it's about finding ways to make the world simple and controllable. What is considered unknowable does not exist. But in fact. That's impossible. Whether you know it or not, it exists. This is rape and self-righteousness in Western academia. Monotheism, the Crusades, and so on are based on this idea. I want you to really understand that the world is objective, it is constantly changing, and there is no definite thing. What is said in the book can never be compared to the real world. Inheritance is important, but it is even more important to carry it forward. ”

Niu Niu doesn't like this thing. I didn't like one that I made specifically for her, she felt as if she had imposed something outside her vision, and the text introduction that was retrieved was suspected of misleading herself.

Niuniu's expression skills are already very good, if you don't like it, you don't like it. It's like having a small body and a body that's getting rounder. Generally, seven or eight-year-old children have reached the time to know that they love beauty, Niuniu looks young, but her mental age is not small.

Exercising at sea is no easier than exercising on land, and for safety reasons, Zhang Chun and his wife always limit the range and depth of Niuniu's swimming. Several times it was a family that secretly went into the water. This kind of swimming is not too much exercise. So Niu Niu protested against this kind of life, saying that the sea is not fun.

The flotilla watched from afar as the war-torn black smoke slid past the land of Luzon, almost following the storm to Kaohsiung. The typhoon continued to invade Zhejiang, and Zhang Chun came ashore in Lianyungang. Like many crew members, get ready to enjoy your vacation.

The typhoon still affected Lianyungang at night. It rained heavily in Lianyungang. The sea was stormy and the jungle on the coast was devastated by the storm.

But just as Zhang had predicted, microbes in the sea air, including algae and plankton that had been swept into the air by storms, came ashore and were transported far inland to the mainland. Most of these creatures will die quickly, but some will certainly survive.

The most obvious is that shallow sea flora and fauna are left behind in the jungle and wetlands with the wind and waves.

After the typhoon passed, Zhang Chun and his wife followed some residents to the coastal jungle wetlands to pick up various products unique to the sea. Zhang Chun found that the beach, which used to be blank due to the ebb and flow of the tide, is now not blank, but overgrown with some plants and algae. Some of the seaweed grows directly to the shore. They are not removed because many fish and shrimp, conch and starfish are left on the beach because of this. Humans are not the only ones who prey on these plants and animals on the beach, some sea turtles, land wolves, foxes, and even omnivorous wild boars and badgers are also churning on the beach. So much so that the tide sometimes does not hide the traces of these animals churning in the sand. Some of the tree species in the mangrove forest extend directly into the sea. These species will not suffocate even if they are completely submerged by the sea at high tide.

The most interesting thing is that some of the algae that hang on the trees because of the tide actually survive directly among the dense aerial roots and branches.

Because it is always moist and many tree species excrete salt from their bodies, causing the water in the tree cavity to be very salty, some of these animals and plants that originally lived in the ocean actually live well in the mangrove forest.

Due to human protection, the number of sea turtles has increased rapidly, and some turtles are slowly gnawing on the seagrass growing on the sand in the wetlands.

They burrow in the sand to lay eggs and bury them. Some turtles are not as docile as they seem, but they are very ferocious.

In fact, many turtle eggs do not hatch, so picking up some turtle eggs is a favorite thing for people to do. In addition to turtle eggs, the mangrove forest is home to a large number of birds. The land administration has an annual assessment of the biomass, and there is no ban on the hunting of turtles and some birds, at least this year. Instead, some rules for "catching the sea" were laid down. For example, how much to keep in a nest of turtle eggs or seabird eggs, etc.

If you are found to be unruly, the punishment is a trivial matter, and it is a shame to be listed as persona non grata, which is a moral issue and will be looked down upon.

Zhang Chun mainly observed the interaction between marine animals and plants and land animals and plants, while Lizhi and Niuniu followed the crowd to pick up some of their favorite foods. Mixed in with the crowd, washed his hands and feet in the freshwater pond, and ran to the roadside restaurant to eat.

Because of everyone's physical differences and eating habits, people are more picky about their diets. So the roadside restaurant was forced to change to a buffet restaurant, that is, you are provided with ingredients and cooking utensils, and you can make your own. Of course, guests are also allowed to bring their own ingredients.

These restaurants are characterized by a wide variety of ingredients, as well as a wide variety of alcoholic beverages and fruit juices. There was even fresh fruit and a juicer for the guests. The small single rooms are furnished like a small family kitchen. It's very distinctive.

Gone are the old restaurants that simply filled people's stomachs. After all, people don't go to restaurants to eat anymore for the purpose of being full. These restaurants are service institutions that absorb personal capital and are jointly provided by the Ministry of Land Management and the Ministry of Commerce. It is very large, and the environmental facilities are not comparable to small restaurants. Most of the people who eat here are with family and friends.

There are few families of three like Zhang Chun who eat. This made the waiter also ask if there were any other guests. Later, the waiter positioned Zhang Chun's family as professors who came here to give lectures. After careful inquiry, I found out that because most of the people live with families, and each family has more or less people who work at home to farm and do housework, so there is nothing to do, and they do not go out to eat. It's better to eat in harmony as a family than with just three people eating out in the cold, unless you and your family are at odds. And Zhang Chun's family doesn't look like they are at odds with their family.

Zhang Chun smiled and answered the question of a waiter who was a bit like the role of an aunt in the neighborhood committee, and finally found that this kind of inquiry and service was part of the waiter's guidelines. Many of the waiters were smiling and communicating with the guests. Of course, some guests will answer the reason for their meal directly and politely, avoiding being asked questions in depth. The waiter let it go with a smile. (To be continued......)
