Liu San was stunned, because most of the popsicle business in Lingao was monopolized by Honghuahui, and Honghuahui made water enamel insulation buckets. No one used wooden boxes to quilt. It was not that he didn't pay attention after coming to Guangzhou.
The equipment at the local hawker was different, but the memory of Lingao was taken for granted and transferred to Guangzhou.
It was a bit embarrassing to be asked like this by him. He had always taken the initiative in today's conversation. Seeing this famous figure in history, he only nodded and asked questions and echoed while he was talking incessantly.
I had already felt arrogant in my heart, but I didn't expect that the other party would catch me making a mistake and ask him an understatement, which immediately made me a little embarrassed.
He couldn't help but secretly cursed himself for being stupid. The hawkers selling popsicles used wooden boxes to quilt. Not to mention that it was like this in Guangzhou, but it was a throwback to the old time and space. Isn't it the same? Which self-employed businessman sells popsicles in enamel jars?
?Forgot completely!
Originally this example was far-fetched, but after Zhang Dai made this point, Liu San suddenly realized that there was no doubt in the conversation just now, and that he had not fundamentally convinced Zhang Dai. The reason why Zhang Dai was willing to have such a humble attitude was that he was indeed right.
These "skills and tricks" are interested in them and are willing to listen to their own nonsense; secondly, because they have the power of "landlord", they have to listen to their own nonsense.
These scoundrels are indeed unrepentant reactionary literati! Liu San looked at Zhang Dai's calm face and cursed secretly.
He laughed dryly: "Sir, you are right. This example is indeed not appropriate."
Zhang Dai was going to Lingao for sightseeing. The "Master of Runshitang" who was talking so long in front of him was the "landlord". He had to take care of him when he went to Lingao. Naturally, he couldn't stop him from coming to the stage, so he said: "Actually, Dr. Liu said
Yes, students also understand. The reason why the half-year-old children in Guangli City can rent an enamel vat to sell popsicles can support themselves is because Guangnan and Hainan are mild and less cold all year round.
Even poor families are willing to buy it to cool down the summer heat; secondly, it is also the power of this skill that can create ice cubes in this "fire-scorching" land in the south. Without this skill, this kind deed may not be possible.
Come."
This is an acknowledgment of the benefits of "the power of technology" to "people's livelihood", but also leaves some room for the "right time and right place". You can't change the day just by relying on miraculous skills.
Liu San thought to himself that this sour guy really had his tricks up his sleeve. The research plan he had discussed with Wu Mu, Mayor Liu and others was somewhat self-righteous.
After Zhang Dai said a few words, he became silent again, apparently waiting for him to continue to show off.
Liu had finished his three words and had to bite the bullet and finish the routine.
"Sir, you are right, the right time and place are also important." Liu San said, in addition to being 'beneficial to people's livelihood', the principle of the technology itself also has many great uses for the military and people's livelihood!" Liu San asked them to discuss the topic again.
The direction of passing was a guide.
Zhang Dai continued to smile. He already understood: in this meeting, from shopkeeper Yang to Yuanlao Liu, despite their different identities, they were all responsible for the work of "lobbyists".
As for the purpose, it is nothing more than to promote the Australian's "magical skills and ingenuity" as a "righteous way" that is as good as or even better than the Confucius' way.
It should be said that Zhang Dai is not disgusted with the "wonderful skills" of the Australians. He has been in Guangzhou for many days, read many Australian books and newspapers, listened to the discussions of people from Yuyuan Society, and has a strong opinion of the various actions of the Australians.
He has a positive attitude. But in his view, this is just a "technique". If used well, it will be of great benefit to the country and the people. If used badly, it will destroy people's hearts. It is far from the "Tao", let alone superior to the "Dao".
"Above.
However, he had no intention of arguing with the Australians. Judging from their painstaking layout, the Australians seemed to have the intention of recruiting him. This made him feel a little proud despite being vigilant, but also a little bit angry beyond the pride: even this
Australians overseas value themselves so much, but the imperial court regards themselves as nothing!
"Sir, please tell me. The students are all ears."
"Mr. Zhang is also a historian, and he knows that the Rongdi people in the north have always been short of iron." Liu San had some free time, so he started by talking about ancient times. "In the past, the Meng Yuan Dynasty fled back to Mobei, and the source of iron tools was cut off, so that bones were
For arrows; when the Donglu rebels started to rebel, they only started with a dozen pieces of armor handed down from their ancestors. The Liao, Jin, and Mongolian Yuan Dynasties were well-equipped with weapons.
The land was cultivated and smelted by the Han family, so the three dynasties of Liao, Jin and Yuan were stronger than all other barbarians in history." Liu San began to spread his view of tool history.
In fact, this argument is problematic. Not to mention Tubo, Xixia is also a northern Rongdi. Its iron smelting industry is very developed, its armor and weapons are extremely excellent, and it does not occupy the sixteen states of Yanyun; during the Sui and Tang Dynasties,
The Turks smelted iron for war on the grasslands and did not rely on Han craftsmen.
Zhang Dai nodded, he knew that the Mongolians were short of iron. A big business of Shanxi merchants at that time was to traffic Mongolian goods out of the country, which was a hugely profitable business, and iron pots were one of the Mongolians’ favorite commodities. As for whether the Mongolians were
If we really need so many iron pots, then it has nothing to do with merchants. Many northern gentry are involved in this kind of business. It is an open secret in the capital.
Liu San also nodded in response: "Since there is a shortage of iron, there is demand. If there is demand, there will be a market, and if there is demand, there will be profits. A great sage from Australia and Song Dynasty said, 'If there is a 10% profit, it will be guaranteed to be sold everywhere.
Use; with 20% profit, it becomes active; with 50% profit, it takes desperate risks; for 100% profit, it dares to trample all human laws; with 300% profit, it dares to commit any crime,
There is even the danger of being hanged.'" After saying this "famous saying" known to everyone by the elders, Liu San paused deliberately, waiting for Zhang Dai to digest this sentence.
Although Zhang Dai is not used to the expression "how many percent", Zhang Dai has read a lot of Australian and Song Dynasty books and newspapers in the past few months, and he also knows that 10% is 10%, and 100% of the profit is "twice the profit".
After a little transformation, I quickly understood this sentence. "This is a wonderful statement! The nature of merchants to pursue profit is clearly revealed!" Zhang Dai praised the sentence.
"To be honest, the biggest demand for ironware is daily iron products. In a household, an iron pot weighs a few kilograms, a hoe and a plowshare weigh a few kilograms, and nails and other bits and pieces weigh a kilogram in total.
There is always one or two kilograms of iron on each person's head. How much iron can be used by an army that uses only swords and guns? Most of the soldiers are spearmen. A spear looks big, but how many kilograms of iron is the spearhead?
A pot-feather arrow is only an arrowhead, not much iron." Liu San continued to analyze.
Although Zhang Dai has never seen regular soldiers or fighting soldiers, Nanjing is still one of the two capitals. Although the standing army is lax, the airs are still there. In the old days, when he traveled to Nanjing with people from the society, he also watched it. Now thinking about it,
It is said that the big-headed soldiers don't need a few taels of iron. They are just some officers such as Baihu and Baihu. The clothes and armor they wear are all paper armor. The real iron weapon on their body is just a fake sword. It doesn't cost more than a few taels.
The weight of kilograms.
But when it comes to firearms, the amount of iron used is huge. A three-eye blunderbuss costs at least ten kilograms of iron, and the number of firearms used by the army is huge.
Zhang Dai still remembers the oracle published in the Di newspaper he saw during the reign of Tianqi. The number of firearms of the Liaodong army listed above, except for the number one and two weapons, which are in single digits, what about the nine-sided divine cannon, the tiger squatting divine cannon, the number one and two
There are hundreds of flannel machines, iron ball cannons, etc. As for iron ball cannons, iron three-eyed blunderbuss, and bird blunderbuss, they can be counted in thousands. You can imagine how much iron material is consumed.
Got it.
As for the men and horses of the bandits in front of them, they are particularly good at firearms, especially cannons. They can "corrode dozens of miles with one shot", and it is said that it takes hundreds of thousands of kilograms of materials to cast a "big general cannon"; the Australian Song Dynasty also
He is good at making large iron ships. An iron ship - regardless of whether it can float or not, the size alone is probably tens of millions of kilograms of iron. There are also dozens of "giant cannons" on the ship. The Kun thief army has
The amount of iron was probably a huge number. Zhang Dai casually agreed and waited for Liu San to continue.
"In order to guard against the Mongols, the imperial court prohibited the export of ironware. Because even if you sell an iron pot, they can find a way to melt it down and make it into a weapon. But this ban is of little use: since the Mongolian demand is strong, merchants often
Try every means to smuggle. Of course, it is not limited to smuggling iron, salt, and grain are the main force of smuggling. As far away as Mongolia and as close as Donglu, there are merchants smuggling goods for them. Well, the truth is still the same: if there is a need, just do it
If there is a market, there will be profits."
Hearing this, Zhang Dai couldn't help but think of some people in the society who liked to discuss current affairs. At a gathering, they mentioned that the reason why the Donglu were able to invade the capital last time was because the profiteers in Jinzhong showed the way to the Donglu.
Suddenly everything turned gloomy, and he couldn't help but sigh. Of course, Zhang Dai didn't know that the reason those few people had such "insight" was because they read an issue of the current situation analysis magazine published by Australia and Song Dynasty that was secretly on sale at that time.
It is true that cannons, fast guns and iron ships all rely on "magical skills and ingenuity", but this is obviously not what Doctor Liu has gone through in such a big circle.
"Among the hardware, only gold and tin are not easily corroded." Liu San paused for a moment, then nodded after seeing Zhang Dai think for a moment, knowing that he had "common sense" in this regard and did not need him to explain more, so he continued
"But the ancient ancestors have long known that the quarried red copper is soft and not suitable for casting. Instead, it is mixed with tin sand and mixed to make bronze, which is not only suitable for casting, but also makes more utensils."
Red copper is harder. Therefore, in the third generation, most weapons and ritual vessels were made of bronze.
"However, although bronze is harder than red copper, it is brittle. The small and inferior coins on the market are mostly mixed with lead and tin, and they will break into eight pieces if they are slightly bumped. The reason is that the physical properties of the coins change after they are mixed with tin.
