Chapter 886 Lantern Festival 5

"Indeed, there will be another test next year, and students who come to Beijing in advance will be indispensable." Gu Chengrui nodded.

"Speaking of the test, Cheng Rui, are you still not going to participate?" the emperor asked.

"No, I'll just guard the medical hall. It's good to guard the medical office, and I can give Chen He advice from time to time." Gu Chengrui said here, thinking of the disadvantages of the imperial examination eight-legged essay, and then looked at the emperor and said: "Your Majesty, have you thought about reforming the road to the imperial examination?"

The emperor was stunned for a moment and asked curiously: "Reform, what if?"

Gu Chengrui said as ignorantly as possible: "I feel that the imperial examination is too simple.

Just like the previous agriculture, medicine, and mathematics required by the Ministry of Housing.

There is also the construction of embankments and bridges, mainly by the Ministry of Industry.

Especially bridge building is not just a matter of simple stacking. There are many things to learn in it.

For example, the local soil quality, the load-bearing capacity of the required materials, etc., all of which require special and in-depth research. Only with Jinshi in this field, will the bridge be built in the future to be stronger and more durable.

Just like lifting a sedan chair, why does it feel much lighter when it is lifted from the outside, and much heavier when it is lifted from the inside?

There is also papermaking and soap making. Although it is just a technology, plant ash and even alkali are used. These are all knowledge. "

After hearing this, the emperor seemed to understand but half understood.

Zhou Ying asked: "Does the emperor recognize the name?"

"Said, I will recognize it naturally." The emperor looked at her inexplicably, not understanding what she wanted to ask.

"It's a balance." After Zhou Ying finished speaking, she went outside and asked for a ruler, a paperweight, and more than a dozen pieces of cardboard of the same weight and size.

Then put the paperweight in place, put the ruler on it with balance, and then began to demonstrate various balances.

Different positions, different weights, let her try it all.

Finally said: "This is the principle of weighing."

Then he demonstrated the principle of the lever to him and said, "That's why the bearer lifts his head when he lifts his baby."

At this moment, the Empress Dowager asked suddenly: "Before, you used building blocks to build a house for Nan Nan, and it seemed that you mentioned the problem of foundation balance."

"Yes, we all know that the foundation is the foundation of the house, but there is also a lot of knowledge in it.

For example, in this restaurant, not only the foundation must be stable, but also many things need to be considered when building the second floor.

Especially the supporting pillars must be sturdy and durable nanmu, mahogany, etc., and they are not chosen because of their good looks, but because of their strong weighing capacity.

Otherwise, if the pillar breaks, the entire second floor will collapse. "

"Are these things useful?" Old General Zhou asked in confusion.

"Of course it is useful, paper, incense, needless to say, they are all good things that improve people's lives.

There is also a bucket of water, why is it okay when it is water, but it breaks when it becomes ice.

There is also the wind that we can see everywhere, and how the clouds floating in the sky are formed.

If we know what's going on, can we change the weather by human power?

Also, why do things fall, instead of flying into the sky, but falling to the ground.

Why, an adult and a child, falling from the same height, will land on the ground at the same time.

Wait, in short, if we want to develop into a powerful country, we can't just rely on the current imperial examination system, which is too simple.

In addition to being an official, people actually have many paths to go. " Gu Chengrui said.
