Li An and Li Yu were having an in-depth exchange, and were building a beautiful blueprint for breeding wild animals in the valley, when they suddenly heard Tang Er's words, and immediately smiled happily.

Tang Er asked such a question, which shows that he has thought about it, he is a child, but he also knows that pheasants can fly, and a relatively closed valley can really trap pheasants that can fly? If pheasants fly out of the valley, then the breeding plan will be in vain.

Regarding this problem, Li An naturally thought about it a long time ago, how could he not know that pheasants have the ability to fly, and not only pheasants have such abilities, even if they are domesticated by humans for tens of millions of years, they can also fly, in many rural areas, many domestic chickens, when they sleep at night, they fly to the treetops to rest.

At the same time, wild animals are more difficult to take care of their families, and it is impossible to lay their eggs in the nest at home like domestic chickens, even if they are eaten, they do not leave home, once their wings are hard, they may fly to other valleys.

Since Li An has decided to breed pheasants, how can he not consider this, although pheasants have the ability to fly, however, the flying ability is not outstanding, and the height and duration of flying are greatly weaker than most other birds, which can be regarded as a wild bird with poor flying ability.

And Li An wants to take advantage of this, breed pheasants in the valley closest to the cliffs, and then, the other three sides are isolated with higher nets, and even the top should be properly covered with nets, so as to ensure that the pheasants do not fly out of the enclosed area.

But in order to allow the pheasant to have a sufficient range of movement, so as to enhance the quality of the pheasant meat, this enclosed area must be large enough, not a palm-sized place, so that the pheasant has enough space to move, and at the same time, can also find enough wild food inside, after all, the valley is lush with vegetation, even in autumn and winter, under the thick layer of rotten leaves on the ground, there are many things to eat, for example, there will be some small insects under the leaves on the ground, and there are many semi-rotten fruits, and a large number of nuts of all sizes.

In this valley in front of you, there is not only a large amount of vegetation, but also many trees are relatively stout, and there are many wild fruit trees, many wild fruit trees are full of wild fruits, and falling to the ground is an excellent delicacy of wild animals.

To put it simply, there will be a large number of bugs in the spring and summer to supply pheasants, and in the autumn the seeds and fruits are excellent and delicious, and in the winter, nuts that fall to the ground and wild fruits that have not rotted are also delicious food, in short, there is food supply all year round, otherwise, how can wild pheasants survive.

However, the number of artificial breeding is relatively large, and it is naturally difficult to meet the demand for food provided in the wild alone, so the food that should be fed is also indispensable, and the combination of feeding food and wild food is the correct breeding method.

Even wild boar farming also needs to be fed, and it cannot rely entirely on scattered food in the wild, otherwise, even if the area of this valley is large enough, it will not be able to support the living needs of thousands of wild boars.

"Father, father, what should I do if the pheasant flies out?"

Seeing that Li An didn't answer, Tang Er continued to ask anxiously.

Li An said with a smile: "If the pheasants can't fly out, my father will make a big net and circle the pheasants so that they will never fly out." ”

"How big of a net is it to cover the whole valley?"

Tang Er continued to ask.

"Yes, why not? As long as my father wants to do it, it doesn't matter how big the net is. ”

Ang Lee said with a smile.

Seeing that Li An's father and son were discussing the issue of pheasants so harmoniously, Li Shi was a little greedy, so he took Li Yu's hand and asked: "Father, I will definitely study hard, in the future, we often come here to play, I want to see pheasants, and wild boars." ”

"Okay, as long as Shi'er studies hard, there will be opportunities here in the future, and my father will definitely bring you over to play."

Li Yu couldn't bear to refuse his son, and said with a smile.

"Oh, that's great!"

Li Shi jumped up happily.

A breeze blew, the leaves above the head made a rustling sound, and a few dead leaves should fall off the branches because they couldn't withstand the force of the wind, and fell to the ground flutteringly.

Li An gently stretched out his hand, took down the dead leaves on Li Yu's shoulder, then looked at the gradually setting sunset, and said, "King Guangping, it's not too early, shouldn't we go back." ”

This time out of the teaching activities, although Li Yu proposed, however, Li An is the real person in charge, if there is any accident, Li An's responsibility must be greater, and it is already very late, it is better to go back early, in case it is dark, the road may be relatively unsafe, even if there is a car, the range of car lights is limited after all, and because of the limited resources, the street lights outside Chang'an City can only extend a relatively limited distance, and to Lishan so far away, It is even more impossible to have street lights, and in the case of a limited scope of implementation, once an emergency is encountered, the probability of an accident is relatively large, in case the vehicle overturns into a ravine and a few lives are lost, then Li An will be very troublesome.

"It's so picturesque, I'm really reluctant to go back! However, it was getting late, and it was time to go back. ”

Li Yu looked at the sunset scenery in front of him, and was indeed a little reluctant, but since the time to go back was up, he had to go back as soon as possible, and safety was the most important thing.

"Woo woo, Father, let's play a little longer!"

As soon as he heard that he was going back, Li Shi, who hadn't played enough, was coquettish, because he knew very well in his heart that after going back, he might not be able to come over again, and the opportunity to come out to play was very rare.

The rest of the emperors and grandsons also had expressions of reluctance to leave, which made Li An and Li Yu a little unbearable, but for their absolute safety, they had to go back when it was time to go back, and they couldn't have the slightest hesitation.

"Children, there are still a lot of fun places in Lishan, we can only see such a small piece when we stand here, let's get on the bus! In the car, we can see more scenery, all the way to the scenery! ”

Li Ang played a small trick in order to make the emperors and grandsons get on the bus willingly, so as to return while watching the scenery along the way.

Sure enough, this trick is still very effective, I heard that I can see more scenery, and most of the resistance of the emperors and grandsons dissipated at once, and they were all willing to get on the bus.

Seeing this, Li Yu stretched out his thumb and praised Li An for his smart brain, and he deceived the emperors and grandchildren so easily, but this is actually not a lie, they can indeed see a lot of scenery along the way, and the road into the mountain is not one, they can take another way down the mountain, and the scenery they see is definitely different from the previous one.

The sun, which was about to set, became much bigger than before, and the red fluttered like a shy little girl, and besides, she tried to hide.

The various trees on both sides of the road, under the light of the setting sun, look quite beautiful, there is a feeling of gold, if the eyes are not good, it is likely to see the distant mountain as a golden mountain.

Because you want to enjoy the scenery, Li Ang deliberately let the vehicle move slowly, so that when enjoying the scenery, it will not cause dazzle, and at the same time, the slower the speed, the safer the driving, and it is not easy to have safety problems, which can be said to kill two birds with one stone.

"What does the sun look like when it sets?"

Ang Lee watched the sunset and didn't forget to chat with the children.

"Like a big fireball."

"Like a big red gem."

"It's like a glowing kemari."

"Like a big plate."

"Like a big, ripe apple."

"Like a big pie."

All the emperors and grandsons answered positively, and a few shouted at the top of their voices.

"Yes, yes, that's right, the sun is round, and what you said is round, but have you noticed any changes in the sun?"

Ang Lee continued to ask.

"Sir, the sun is getting bigger."

"Sir, the sun is getting redder."

"Sir, the sun is getting darker."

"Sir, the sun is getting shorter."

The emperors and grandsons scrambled to answer.

Li An nodded with great satisfaction: "You answered very well, but has the sun really changed?" ”

"Sir, the sun hasn't changed, it's what we see, in the morning and evening, the sun refracts a lot through the air and looks bigger, and at noon the sun refracts less through the air, so what we see is smaller."

Li Shi replied.

This knowledge was naturally taught to them by Ang Lee, and after they learned it, they digested and absorbed it, and when Ang Lee asked them, they would be able to answer it.

"Yes, Shi'er answered very well, very good. Have you ever heard of Kuafu chasing the sun? Can anyone tell me the story of Kuafu's chasing the sun? ”

Ang Lee praised Li Shi a few words and asked new questions.

"I'll tell you, sir, I know."

Li Huai said loudly.

"Huai'er, come on!"

Along the way, Li An has always taken care of Li Shi, after all, his father is next to him, but he always asks Li Shi, and he is too cold to other people, which is a little unfair, and it is also very necessary to take proper care of others.

Li Huai got the opportunity to answer, and answered the questions very hard, and told all the questions about Kuafu, and the answers were basically from a source, which shows that his knowledge is still very good.

As for Kuafu's chasing the sun, in fact, there are many versions, and the versions of each era are different, which may be due to some deviations in the process of people's word of mouth.

For example, many of the sayings in our lives are mistakes that occur in word of mouth, and then the mistakes will be wrong, such as marrying a chicken and a chicken and marrying a dog and a dog, which is a typical mistake, originally it was to marry a beggar and marry a beggar, saying that marrying a beggar is to follow the beggar for a lifetime, and marrying an old man is to follow the old man for a lifetime, and it has to start from the beginning, but even if there is a mistake in word of mouth, it doesn't matter, and the meaning of making people from the beginning to the end has not changed in the slightest.

The most widely circulated version of the story of Kuafu chasing the sun is that in the era of the emperor's dynasty, one of the leaders of the Kuafu clan wanted to pluck the sun and put it in people's hearts, so he began to chase the sun, when he was thirsty, he drank the Yellow River and the Wei River, and was ready to go to the big lake in the north to drink water, but he was dying of thirst on the way, his cane turned into Deng Lin, became a peach garden, and his body turned into Kuafu Mountain.

It's a myth and legend that there is no such thing as a giant like Kwafu on Earth, but this story reflects the reality.

Some scientists of later generations gave a more reasonable explanation, they believed that Kuafu was not a giant, but a tribe, and a nomadic tribe, a group of people who chased water and grass, this tribe encountered a rare drought, in order to survive, they began a migration road, began a great migration in search of water.

And because the drought was so severe, when they went to the Yellow River, soon the Yellow River also dried up, and they continued to move forward, and after living in the Wei River for a while, the Wei River also dried up, and in order to survive, they continued to migrate, wanting to live in the great lakes in the north, but finally died of thirst in a swamp.

As for why migration is associated with chasing the sun, it is because the migration of the tribe must have a direction, and the migration direction of the Kuafu tribe is the direction in which the sun sets, that is to say, the so-called Kuafu chasing the sun is actually the migration of Kuafu according to the direction of the sun's fall, and the purpose of migration is to find a water source, therefore, in this sense, what Kuafu is really chasing is not the sun but water.

This explanation is still quite reasonable, and has been recognized by many scholars, who feel that this is the case, and as for the myth itself, it should be an exaggerated modification of things artificially, thus creating a completely absurd mythological story.

The other version, which is linked to Prometheus in the West, believes that Kwafu chased the sun in order to steal fire, so that human society could enter the stage of fire civilization, and could eat cooked food, thereby increasing the life span of humans.

There are also versions that Kwafu chased the sun, possibly a shaman in ancient times who learned a witchcraft ritual day by day, and that Kwafu died in a witchcraft activity begging for rain.

And there are two situations in the description of Kuafu in the Book of Mountains and Seas, one is dying of thirst, and the other is killed by Ying Long, and Ying Long is a general under the command of the Yellow Emperor, who once killed Chi You and Kuafu.

In short, there are so many versions and interpretations that there are even more and more people who will express their opinions, so that there are more and more versions of this story.
