"How is this possible?"
The words that the host blurted out were exactly what many viewers were thinking at that moment.
How can such a large wooden structure be held together without nails or glue? Even if they build a cabinet at home, they still need more than a dozen nails!
Li Taidou laughed and said, "Have you ever thought about how the ancient people built houses without modern glue and standardized steel nails produced in factories? Especially those seven-story pagodas?"
"Yes!" The host looked puzzled. "Can you explain the reason to us?"
"It's simple. They used a special architectural structure aesthetic—"
“Mortise and tenon structure!”
Li Taidou took out his tool bag and found a few pieces of wood that had not been removed after the construction. He quickly processed the wood with the tools at hand, and then processed the two straight wooden sticks into the shape he wanted. Then Li Taidou put the two sticks together.
“Crack!”
"Come, come and see if it is stable!"
The host took it and shook it, but it didn't move at all. He said in surprise, "Really! It's so amazing that it can be connected together in this way!"
The audience also widened their eyes.
To be honest, when this structure was used, almost all the audience could understand its principle. But it was like a fish in water crawling onto land for the first time. They had never thought of this possibility before.
It was as if a brand new door had opened.
Can woodworking be played like this?
This was not all. Li Taidou took out another nail and nailed the two pieces of wood together. He seemed to deliberately not nail them so tightly, and then handed the wood to the host.
"Try shaking this again."
After shaking it, the host couldn't help but say, "It feels looser and looser."
"Of course, simply connect the wood together with nails. As it is used, the gap will naturally become larger and larger. Over time, it will become like this..." Li Taidou shook the two pieces of wood apart, "and become a loose structure."
"On the contrary, if you look at this kind of interlocking structure, if you shake it, the wood will only get deeper and deeper into the wood."
“Amazing!”
The host turned his head and stared at the building behind him and said, "You mean, the wooden structure of this building is all made of mortise and tenon joints?"
“Yes, that’s why I admire this building so much!”
The audience was also shocked... The house built by Xu Shang was so awesome?
At this time, the host asked again: "Academician Li, this kind of craftsmanship is really amazing, but why is it so difficult to see such woodworking skills in our daily life?"
Just as the host wondered, if the rise of the Internet had not allowed many folk craftsmen to showcase their skills, many people would probably never know in their lives that there are so many treasures in our history and culture!
Faced with this question, Li Taidou sighed and gave the answer.
"This construction method has many advantages, but it also has a fatal disadvantage, which is that it is difficult."
The host was stunned. So the only drawback of this thing is that it is difficult?
But the problem is, when I watched Li Taidou operate it just now, I thought it was quite simple. It seemed that as long as you understand the tricks, you will naturally master it.
Then, the host saw Li Taidou smiling at him, as if he could see through him.
"Let me demonstrate and you'll understand. For example, if I want to make a stool now, I'll make a mortise and tenon structure on the left and the same structure on the right... Do you see any difference?"
After taking a closer look, the host shook his head and said, "There is no difference."
"Now let me put them together and you can see..."
The host was stunned for a moment and couldn't help but say, "It's crooked."
"Yes, it's crooked." Li Taidou put down the tools in his hand and said with emotion, "If you use nails to connect, if the nails break, you can just replace them. But if you use delicate structures to connect, you have to start over again if something goes wrong. But this kind of structure requires very high precision and it is very easy to make mistakes."
“It’s so difficult!”
The host couldn't help but shake his head and sigh. He originally thought that this was just a layer of window paper, and it would be easy to master as long as it was broken.
But after Li Taidou's actual operation, he suddenly realized that it would not be so easy for an outsider to make a stool with it. It requires the craftsman to have a deep understanding and control of this skill.
Wait, if that's the case—
The host turned his head suddenly and looked at the house behind him.
This, this, this…
If this skill is so difficult——
What about this house?
…
The audience obviously realized this.
“What level of skill is required to build this house to such a perfect degree?”
The audience was immediately excited. Many people instantly turned on their computers and rushed to the bulletin boards and forums to post this shocking news.
"Go watch Cultural Sojourners!"
"Cultural Sojourn? What is that?"
The confused audience turned on the TV and searched for information about the program on their computers.
You wouldn't know unless you searched, and once you did, you'd be shocked.
It turned out to be a cultural and educational program produced by CCTV?
Let’s take a look at the background of the speaker, Huazhong University of Science and Technology…
