The next day 63962453287387629 took me on to the sculpture gallery, dance and instrumental music gallery. There are many kinds of sculptures here, and the materials are also very extensive, including stone carving, wood carving, bamboo carving, charcoal carving, root carving, jade carving, ivory carving, shell carving, coal carving, walnut carving, jujube core carving, eggshell carving, rice grain carving, clay carving, gypsum carving, carbon silicon carving, metal casting, porcelain firing and brick carving, etc. Many of the dance poses in the dance hall are sculptural, as well as coherent dance photographs, as well as dance costumes and utensils. There are hundreds of types of wind music in the instrumental music hall, as well as percussion, string instruments, keyboard instruments, wind instruments, etc., some of which I have never seen or even heard of.

63962453287387629 said to me: "These exhibits are collected across the ages, and some of the lost ones can only be imitated in modern times, for example, some dances can only be shaped by recorded historical materials such as rock paintings." I will take you to visit today to explain the historical materials that I know about the emergence of private ideas, and the historical materials of people enriching their material and spiritual wealth, and I will leave more to you to understand slowly.

You can see that this group of sculptures is a record of the scene of prehistoric people farming, the man pulling the plow, the woman supporting the plow, the child planting the soil, and the family working hard in the era of low productivity. You see that except for the women, the rest of the people are naked, which is a true portrayal of people's living conditions at that time, that is, when people have no material life, shame is placed in a secondary position.

If you look at this group of stone carvings, this is a prehistoric work, you don't look at the rough workmanship, but it is an extremely valuable exhibit. You can see that these people are not even clothed, and their gestures are very beautiful, and they seem to be based on the action of farming. You see the man with a javelin in his hand, one leg raised, leaning back, much like a hunting man. Another man has leaves in his mouth, his hands hitting the animal's lute bone, his legs bent and dancing. It shows that people had a division of labor at that time, with men hunting and women farming. It can also be seen that when people's living standards are not very high, dance entertainment began to be had.

If you look at these dozens of smooth pieces of jade, they are of different sizes, with a round hole in the middle, which is used to thread ropes. We experimented with hanging each piece of jade and striking it, which can produce different high and low sounds, which means that we can play music. And this broken jade piccolo, which we can also play after replicating it. These tell us that there are these musical instruments that can be played, and of course there are songs, that is, you can dance with accompaniment and sing with accompaniment.

And I found that on the walls of some caves, there are also some hieroglyphs organized together, and the coherent analysis seems to describe mythological stories and poems. For example, they write about birds flying in the sky, fish swimming in the water, white clouds drifting, the sun shining warmly on the ground, flowers blooming in the fields, and small rivers roaring. These are analytically read and written, and may have other meanings.

I also read another passage about a baby who was taken by an eagle who did not hurt him, but raised it. The child also grew wings like an eagle and flew in the sky, connecting the sentient men and women with threads, so that they could love each other. This is also a beautiful story written by people, so as to hope for the good wishes in their hearts. ”

We watched together for a while, and she said that she was going to give lessons to the students soon, leaving me alone, and she hurried away. As I browsed, I found a very peculiar instrument, which was a row of animal ribs, each of which was hollowed out in the middle and arranged together according to its length, and I realized that this might be the original pan flute. Without her by my side, I can only guess.

I browsed by myself for a while, and found it boring, so I went back to my 63962453287387629's office and waited for her to come back, passing the time by flipping through her collection of books. When I was flipping through the book "Climate and Environment", I found that there was a record of a catastrophe that almost wiped out the life of mankind in history. That was about 3.05 million years from now, and the carbon star was attracted by Yuanyang, deviated from its orbit, and the distance between it and Yuanyang was much closer. Under the influence of gravity, the structure of the carbon star has changed, and a global earthquake has occurred. On the land on which living things depend, there are places where they are uplifted, and there are places where they collapse. The movement of the earth's crust also affects the change of climate, and there is a global rainy day, with heavy rain under thick clouds. At this time, the uplifted areas formed plateaus, and the collapsed areas were submerged by the ocean, and the plains were also flooded, and most of the living things were wiped out. Of course, humans are not immune, people in the subsidence areas are buried at the bottom of the sea, and people living in the plains are struggling in the floods, most of them dying of starvation and drowning. Only people living in uplifted areas were spared, but the living environment became very harsh, but fortunately, people have a strong ability to adapt to environmental changes, and they also have the instinct to adapt to changes in the environment, which is still much better than other animals.

When 63962453287387629 came back, I told her about it. She listened calmly, and began to explain to me her relevant content in [Interpretation of Human History]:
