I live in prehistoric

Poplar trees grow about one meter in height every year, and they can become useful in ten years, eventually growing to about 20 meters.

Gong Xi took Xiangzi to count the growth rings on the tree stump, one circle, two circles...

"Xiangzi, you are 19 years old! You are two years younger than me!" Gong Xi shouted excitedly and surprised at him.

"nineteen……"

"It doesn't look like it~"

"Under the year? Oh, what a love!"

"So tender...I really like it!"

"Stop talking nonsense there, come here and help!" Fei Shi'er's father saw that the two of them were reciting some kind of mantra there, and they were holding the tree stump with serious expression, and yelled.The house was almost finished, and he was eager to see what the finished product would look like!

Xiangzi was interrupted by the man's yell and lost the chance to speak.He was a little ashamed, how could a big man cry and cry?

Gong Xi pulled him up and ran towards the tree-carrying team.

"Pink youth, and blood~"

"Do you know, fortunately we are graduating early now, if it was a few decades earlier, we would have to graduate at 23 for undergraduate... The host would be older."

"Upstairs, just think about it!"

"I also want to find a young wolf dog, it doesn't matter if you work hard~"

"Upstairs, please don't try rashly..."

Before, the two of them could build the roof, but now with everyone's help, it's even easier.The wooden beams are stuck in the grooves, and a few thinner branches are used to fix the roof, and the long and thin earth bricks are arranged to cover it.Tomorrow, it will be firm if it is wetted with wet soil.

The house is really not that big, it is only a little more spacious than the previous thatched cottage, but it is enough for two people to live.In the future, the thatched cottage can be cooler for sleeping in summer, and can be used as a warehouse in normal times.

"Okay? Sprinkle flowers~"

"It's not easy! Spread flowers!"

"Scattering flowers~ The house is built, it's time to get married and enter the bridal chamber?"

"Upstairs, it's fine!"

Everyone is very happy.Gong Xi scanned the rough and dark faces of the men, and was moved by the warmest side of human nature.

The burnt earth kang ushered in the grand opening.Large pieces of pork are stuffed in, vegetables and mushrooms are put in, and freshly grown bean sprouts are added.Stew, add salt, and take out of the pot... Each family serves rice "together in the grand event".The smell of meat and laughter filled the darkening night.

This was the most shocking day for Gong Xi to come here.Like Xiangzi, he blended into it.

"The significance of human beings living in groups is also here. Although there are frictions and bumps, they cannot be isolated."

"It looks very happy~ I think of a word called 'Jiuchi Roulin'? Although there is no wine..."

"Upstairs, that's not how the word is used..."

"Xiao Gongxi's live broadcast always moves me! The last coin is for you!"

Before going to bed, they sweated all day, and the two of them took a shower.They were all secretly looking at each other, but they didn't notice each other...

Xiangzi washed her underwear by the way, and handed it to Gong Xi who was still naked. "I... the injury is healed, and the disease is also healed. You are used to wearing it, so I'd better give it to you."

Gong Xi thought for a while, only took the underwear, and said: "I don't wear this awkwardly, you are awkwardly dressed, just right..." and put it on directly.

Seeing his appearance, Xiangzi's eyes flickered, Gong Xi couldn't see his expression clearly in the dark.

"You don't wear clothes yet? You'll catch cold!" Gong Xi scolded, thinking to himself that he really is a big boy!Stand up and put the underwear on him over the top of his head.

Xiangzi looked at the waist and abdomen that was close at hand, it was firm and flat, with a shallow and small belly button, and a little honey-colored skin, and unconsciously put her face on it.

Gong Xi trembled, he was embraced by Xiang Zi.

"Gong Xi, it's great to have you here." Xiang Zi said softly, spraying hot air on Gong Xi's stomach.

He sighed softly and put his arms around the man's broad shoulders.I will try my best to make your life better, Xiangzi.

"Oh, I painted the wall~"

"I've always thought that the whitewashed wall is very artistic, but it turns out that the real version is like this..."

"Yeah, it's just dirt~ but it definitely doesn't contain formaldehyde!"

"Smear it all over your body, and then you can play some love games..."

"Trust me, they will finish brushing seriously..."

That's right, with so much work to do, how can I have time to play those messy little games... Although I am a little excited.He took a look at Miaoxiangzi's upright attitude towards work, but let it go.

After all, they can't flirt together, so it's better not to mess around.

It's embarrassing to say that Gong Xi lives in a city full of tall buildings, but he is afraid of heights!Xiangzi just smiled and comforted him, "I can do it myself!" Swish up the mud brick roof.

Gong Xi was still worried that the top was not strong enough, so she felt relieved by the way.

"The old man's maiden heart has been aroused again!"

"Xiangzi is full of hormonal charm~"

"Xiangzi like a monkey!"

"Climbing trees and houses, he is a professional!"

The inner and outer layers are separate, and the gaps in the roof are repaired, only the doors and windows are missing.

Xiangzi's house had no windows before, so when it got dark, you couldn't see your fingers in the house.I heard that people opened skylights in the earliest days. Gong Xi felt that it was too inconvenient, so it would be better to leave a piece of wood on the wall and use wooden boards as windows.

The style of the door has undergone many evolutionary forms. Gong Xi thinks that the best door that can be made at present is the "mirror version door": thick wooden boards are spliced, and the back is connected with horizontal wooden boards.It is similar to the tabletop production method he thought of.

Gong Xi held up the stone hammer and hammered it down against the wooden nail.The peg broke...and again, it broke again.

It's not Gong Xi's style to give up easily, but he thought it was so difficult for Xiangzi to cut a branch into a finger-sized nail with a stone, so he didn't "heart" to try it anyway.

"Look! Who said Gong Xi is weak? She has great strength!"

"Use ingenuity, wood nails wood, you must not use brute force!"

"But to be honest, nailing the door like this is quite simple, but the tools are too backward~"

Xiangzi touched the wooden nail from Gong Xi's stiff hand, raised the hammer and dropped it, without thinking, the two layers of wood were combined together...

Gong Xi couldn't help clapping her little hands.

"What does this mean?" Xiangzi looked at him curiously.

"You are great!" Gong Xi explained with a grin.

"I only said that after the fact..."

"Upstairs, you won! My ears are even redder!"

"Oh, if you like it, you have to say it boldly!"

"You guys complain too hard, be careful that you don't even have to eat sugar in the future~"

"Yes, there is no meat, but the sugar should be cherished!"

My little good mood is dispelled by you, do you know that?But Xiangzi's innocent and shy face made him forget those little unpleasantnesses.

Xiangzi, take a sip?Suddenly thinking of such a sentence, he boldly poked the man's face, and happily went to cook.

The man covered his face with one hand and smiled silly.

The barrage is boiling...

After being happy last night, the bean sprouts were almost wiped out, and Gong Xi soaked another pot of soybeans.

Soak the dried fungus and add it to the leftover hodgepodge from last night.The aroma of meat dishes that are cooked again is more intense.

Xiangzi hugged the nailed low table, smiled and indicated that she would use this table for dinner.

Gong Xi expressed concern about whether it was strong, so Xiang Zi sat on it and turned it around.The last smile is probably: Look, it's very strong!

"Yo yo, naughty and cute little Xiangzi!"

"Well, good, very 19 years old!"

"Tossing around at the dinner table like a brat~"

"There is a table to eat, I am very happy."

"This is the first piece of furniture we got married..."

Oh, why are you all thinking so much... It's as if it's really the case... The vegetable bowl is brought to the table, and the two of them are used to holding the bowl.

"Gong Xi, this black fungus is delicious!" Xiangzi's exclamation instantly made him play, and he burst into laughter when he saw the barrage.

"Eat more if it's delicious!" What could he say?Xiangzi is good, don't make trouble!

"Gong Xi, how did you know about black fungus?" Xiangzi started talking...

"I have eaten... Xiangzi, it is a kind of fate to find something to eat." He wanted to end the topic about the fungus.

"Fate... what is it?" Very good, it diverted his attention unexpectedly!

"That's how you guys are together..."

"Fate is hard to come by..."

"The fate of the broadcaster...is too difficult!"

"Some TV dramas always have lines like 'There is no fate'..."

In view of the low height of the table, they finally made a few benches, which were more coordinated.When Fei Shi'er arrived, the newly made "furniture" surprised her.

"Sit and watch!" Gong Xi pushed her shoulder and pressed her on the bench. "Is it okay?"

"Hmm! This thing looks good and is light." Fei Shi'er commented.

Gong Xi chuckled, and said, "This way the jar can save food." A very cold joke...

Sure enough, the little girl didn't catch the joke, but nodded seriously.

After washing, Xiangzi sat over and asked, "When will your father build a house?"

The little girl probably didn't expect Xiangzi to ask so directly, and said a little shyly: "He asked me to ask a casual question, saying that you are all right..."

"Okay, go back and tell your father, we'll just wait for him to order us!" Gong Xi stroked the girl's hair, and suddenly thought of braiding her hair.

Fei Shi'er didn't know what "Uncle" was doing on her head, but she knew that he would not harm her. "Brother Xiangzi, are you all covered?"

Xiangzi watched Gong Xi's movements attentively, and when he was asked, she smiled and replied: "Well, everything is ready! I will live in when it is dry." Then he added: "Come and see at dawn!"

The three-defense style was tied for her, which is not difficult, neat and generous.The little girl pulled her hair and liked it very much.

Xiangzi suddenly said: "Me too!"

Gong Xi didn't know whether to laugh or cry, but he wanted to teach Fei Shi'er, so he grabbed a strand of his long hair to show her.

"Like a tribal chief..."

"Hey, I can be so happy playing with my hair, I'm envious!"

"It's rare to see this kind of tie~"

"Big braids like this used to be all the rage."

"Isn't there a dynasty that regards braids as life?"

The author has something to say: 1 The window was invented with the origin of the building. When the semi-cave dwelling evolved into a primitive ground building, in order to eliminate the large amount of smoke generated by the bonfire inside the house, openings appeared on the fixed roof for ventilation, smoke exhaust and lighting. The structural style of the window was called "chimney" in ancient times, that is, "skylight", which is the prototype of the window; because it is difficult to avoid the invasion of rain and snow.So "牖" appeared.牖 means "side window", which is a hole in the wall.The emergence of 牖 is a major breakthrough in the history of the development of ventilation technology in ancient my country, reflecting the great progress of ancient science and technology in my country.We can see the clues in the Western Zhou Dynasty.From the Sui and Tang Dynasties to the Song Dynasty, the development of windows became more and more mature, but mullion windows were still the most common; in the Ming and Qing Dynasties, sill windows and branch windows became the mainstream of the times.

2 Gates: According to records, Chaoshi - No.1 who first stepped into the gate of Chinese architectural culture.Realizing a great change in the history of human habitation, the Banpo site in Xi'an shows exactly this type of "nest" relic.Nest building is the real beginning of door consciousness.The earliest known human dwellings in our country are natural caves. "A place where caves lived in the wild in ancient times", countless strange and deep caves provided the most primitive home for human beings, and the grass cover at the entrance of the cave was probably the earliest door.After entering the slave society, the earliest large-scale wooden frame rammed earth buildings and courtyards appeared in our country, and thus specifically defined doors and windows appeared.The main form of the gate is the banmen, which can be seen in the Shang Dynasty bronze vessel Fang Yu.

3 Women in our country have a long history of braiding their hair. With the emergence of human aesthetic consciousness, people in the Neolithic Age began to comb their scattered hair. Some of them cut off their long hair; some tied their hair with headbands; braid.On the neolithic painted pottery pots of scholars from Shangsunjiazhai, Datong County, Qinghai Province, there are scenes of people dancing and singing hand in hand, and a braid of hair hangs down from the top of each person's head.From the Neolithic Age to the Han Dynasty, the hair style with a braid on the top of the head was very popular (Shanbian style).
