The people of the Ministry of Works were not well received in the imperial court.

Yang Su's people look down on the Ministry of Industry at all, because they are not like the Ministry of Households, which controls the money bags of the world, nor like the Ministry of War, which controls the military power of the world.

The most common part of the Ministry of Engineering is an old craftsman, as well as some drawings for shipbuilding and agricultural tools, and craftsmen for building some houses and bridges.

These people, in the eyes of the people at that time, had a very low status, so this squire of the Ministry of Works had never seen the emperor and the crown prince, which was a bit ridiculous.

But that's just the way it is.

And today it was Li Shilang who came, he was just responsible for bringing some craftsmen over, and then he was accompanied to eat meat and drink wine, and he didn't care about Emperor Yang of Sui and his party at all.

Yang Guang's conditions made the craftsmen and old farmers in the household department confused.

Those craftsmen have lived in Luoyang City for a long time and witnessed a lot of things, but there has never been such a request as today.

In the winter, how can there be such a strange requirement?

What is this greenhouse used for?

"Qi Qi, this master, I once made a earth dragon for someone, but it is very warm, but that kind of house is all tight, there is no way to transmit light, and it is all built of mud and stone......"

"I once made windows for some nobles, which were made of fine oiled paper, but the price, the price is staggering, more expensive than building a house......"

At this time, the paper was not something that ordinary people could consume, not to mention the special white oil paper, which was too expensive than gold!

At this time, most of the writing characters are made of bamboo slips, and there are a few pieces of paper, but the price is not cheap.

"Oiled paper? No, when it's windy, rainy, and snowy, the oil paper doesn't work at all, and the thing needs to be transparent and warm, and the price is relatively cheaper......"

Not to mention the cost of using oiled paper to make a greenhouse, it is windy and rainy.

So it simply doesn't work.

"Oil paper can't do it, that, that, this is really not the house you want, anyway, I've lived for decades, I really haven't seen ......"

The craftsman touched his head and said with a sad face.

I can't take this job, I really can't take it, I have never heard of what this noble man asked, and with his insight and experience, what he can't do, others will definitely not be able to do!

"Yes, how can you make something that you can't make or have never heard of, and what is this thing for?"

"Warm and translucent, are you talking about a warm house?"

"That's not right, how can there be such a ......"

The few people who brought it and those farmers were talking about it at this time, because they didn't know Yang Guang's identity, they were a lot less in awe, but a little more questioning.

They all felt that Yang Guang's proposal was incredible.

"I want to make a greenhouse for growing vegetables, so that there will be no shortage of vegetables in the long winter, and the cost of this greenhouse should be low, so that some wealthy families can also follow suit and make some greenhouse ......"

In later generations, the vegetable greenhouses used plastic, so that eating vegetables and fruits in winter became a very common thing, and the cost was naturally not high.

There was no plastic at the time of the Great Sui, but Yang Guang felt that a replacement should be found.

As long as he is willing to use his brain to think, it should be easy, as a superior, all he has to do is to put forward a certain goal, or concept, and the specific operation will be handed over to Xiao Shan and those craftsmen, as well as the old farmers to discuss!

After listening to Yang Guang's request, those who couldn't turn their minds were stunned.

Have vegetables to eat in winter?

What a luxurious thing it should be, I'm afraid that today's majesty, if you want to eat a bite of vegetables in winter, I'm afraid you can only think about it.

Because it's so hard.

The winter in Luoyang is dry and cold, the whole land is scorched yellow, and there is very little green to see, even if the trade is more developed now, the goods from the south can be transported to the north.

But something like vegetables, which is delicate and not easy to keep fresh, is also very difficult to get over, so don't mention the fresh taste.

"Your honor, with all due respect, your kind of thinking, I'm afraid that your majesty today can rarely eat fresh vegetables in winter, this is too luxurious......"

"It's for a bite of food, is it worth it?"

“……”

At this time, Xiao Shan was in a hurry, Yang Guang did not indicate his identity, and there was no taboo for these people to speak.

His Majesty began to ask to see them, and he coughed on the side, but the craftsmen and old peasants did not react and restrained their words.

Yang Guang glanced at Xiao Shan, as if he was smiling, but he threw this problem to Xiao Shan.

He turned around and led Yang Zhao alone to walk on the wasteland, and asked him, what did you think of the words of those people just now?

Yang Zhao frowned.

"Father, for a bite of green vegetables, is it too exciting? Yushi knows about it, and he will impeach, but in fact, if you don't eat vegetables in winter, it's nothing......"

Yang Zhao was actually able to come out, and he was very happy today.

From the day he fainted and woke up, his father forbade him to stay in the house all the time, let him go outdoors, and he slowly found that his body seemed to be much better, and he would not be out of breath after walking a distance.

Today, he was able to follow his father out of Daxing Palace and come to this farm, for him, he especially liked it, but he heard that his father went to such great lengths to eat a bite of vegetables.

This seems to be different from what the prince and the prince taught him.

Taifu said that the way to be a king should be like the emperor, be diligent and thrifty, and set an example for the people of the world, not for the pursuit of enjoyment and luxury, and let people all over the world run around for it.

"No, that's not how the emperor behaves, today my father is going to teach you the way to be a king......"

Yang Guang looked at the barren land, stood still and pointed to the ground under his feet.

"Although this piece of Zhuangzi is large, there are more than 100 families around, most of them live by farming, and the grain they produce and the silver they earn in a year are actually less than ten taels, and you look at the houses of those people, and their children......"

This Zhuangzi is very poor, but after all, it is outside Luoyang City, and most of the houses where the peasants live are mud and hay, and then they are piled up with wood, and the thatch on the roof will be blown away when the wind is strong.

The windows of many homes are high and small, and they are randomly blocked by a few wooden boards, which is particularly poor and sour at a glance, and the golden splendor of Daxing Palace is simply one in the sky and one is underground.

Moreover, the clothes worn by many farmers are layers of patches, and even from a distance, Yang Zhao has seen some children running around the fields naked and barefoot.

Those people only dared to peek at them curiously from a distance, and they didn't dare to approach at all!

Although Yang Zhao was young, he also knew that those people were very poor, very poor!
