"The rafts in the south of the Yangtze River, the bamboo rafts on the Li River, the birch bark boats on the Heilongjiang River, the yak rafts on the Qinghai-Tibet Plateau, the sheepskin rafts along the Yellow River in Jiuqu, etc., I believe that the students have never heard of these things. They were the earliest ships in the Chinese area. ”

Although the long-awaited explanation of the students began, Su Bingyan's enumeration made them suddenly feel that there were a lot of ways in it.

Sure enough, I heard Su Bingyan continue: "These ships appeared in the primitive period when the technology was still relatively backward, and the material accumulation at that time was not abundant, so the conditions were quite hard, and the ancient ancestors were still able to make these tools with their own hands, which fully means that they have begun the journey to challenge nature." However, the journey was destined to be very arduous, and from the traditional structure, the water vehicles made at that time were basically simple boats and rafts. And with the development of technology in our time, I am afraid that many people have looked down on these small means of transportation. ”

Hearing Su Bingyan say this, there couldn't help but feel a strangeness underneath, although everything slowly appeared from nothing. But compared to the basic contributions made by their ancestors, the more advanced technology is now, the more it can be contrasted, the more it means that the work of their ancestors is so arduous and important, which makes them reverence their sacred ancestors as much as the Confucian scholars.

However, Su Bingyan has just said that to learn from ancestors, we must learn their spirit, but we can't repeat their trajectory, that would just copy the ancestors, not open up new fields like the ancestors. Therefore, there are also people who support YY's opposition and think that while worshipping ancestors, we should imitate our ancestors, rather than saying empty words here.

His remarks immediately resonated with his classmates, but at this time the Soviet Union seemed to have done something superfluous, pouring cold water on their ancestor worship.

"It should be noted that the so-called Yellow Emperor was not the inventor of the boat. As for the explanation of the buoyancy of water, there are similar discoveries in different places, because nature is like this, he has laid down the laws of physics for us, and those who can discover and use it will become powerful, and if there is no ability to do this, there is no ability to understand the laws of nature, and nature will not be able to apply the laws of nature to ordinary life and even war. ”

This method provides a more detailed explanation of the path of imitating ancestral spirits. Instead of simply calling on everyone to learn the spirit of their ancestors, they can neither sit back and eat nor copy their ancestors. The most practical path of the spirit of our ancestors was to explore the laws of nature and apply them to everyday life and battles.

Although everyone still can't understand the mystery of this, some people even immediately raised questions, saying that the reason why the two systems are strong is because they know the laws of nature better, and they are puzzled in this regard, because although the tactical equipment of Liangzhou Qiqi is sophisticated, there seems to be no direct connection with the laws of nature.

Su Bingyan didn't answer his question directly, he just said lightly: "This classmate, today we are talking about ships, if you discuss productivity, I have some other theories that can communicate with you, but for the secondary application of some natural laws, it is indeed very important, our imagination may be one of the important factors to promote the enrichment of our tools, it is undeniable that this has played a huge role in our development, but it must be pointed out that the focus is on this and ignores the exploration of nature, It will lead us astray. ”

"The progress in this regard has given us a great warning, the rapid development of our ships is not comparable to other civilizations around us, in addition to the pre-Qin era far ahead, we have never lagged behind in the later development, although the short-lived ghost of the Qin Dynasty did not leave the building ship left over from the Spring and Autumn Period, to make a large-scale invention, but at the same time the Western Great Qin Empire did not have much achievement in this area, they just made full use of the galleys in the cypress sea. There is no doubt that at that time, they were fully aware of the importance of ships in the war, and we still paid attention to this until the time of Emperor Wu. ”

"At this point, we are far behind the Great Qin Empire in the West, but this is not our problem, our coastline is generally an arc protruding in the direction of the ocean, which makes us although surrounded by the sea on three sides, but we can't find a foothold on the other side of the sea, so it can't become an important way for us to develop abroad, at least in the beginning, we have to take risks to explore, but we have very few achievements in exploration at present, because the islands scattered around are not as easy to find as imagined, Therefore, in addition to finding internal discoveries such as Zhejiang from Shandong, it will take time to expand outward. ”

Shandong Zhejiang, of course, was learned from the books that came out of the Liangzhou system, so Su Bingyan didn't need to avoid anything here, anyway, many of the people present also took a similar approach when they first received geographical education, but their concept of Shandong here is very large, almost including Henan, Hebei and Jianghuai, as for the later concept of Shandong Province, of course, it is impossible not to be among them.

From the Jiaodong Peninsula in Shandong, the sea route to Zhejiang is likely to be the earliest overseas discovery in the Laizhou and Dengzhou regions. But they found their own backyards, but the routes were probably in the hands of the sailors.

Otherwise, Gou Jian later went north to attack Qi and other places, and would not have thought of moving his capital to the vicinity of Langya in Qingdao in later generations, which was not Langya in the Wei and Jin dynasties. It is a famous local mountain peak where Qin Shi Huang also performed sacrifices after he ascended the throne. As for the well-known Langya Mountain in the Houshi, it is a replica of this famous seaside mountain, or a copycat version, but the copycat version later became even more famous because of an article by Ouyang Xiu, so that people have forgotten the Langya Mountain that Qin Shi Huang once defeated.

Later generations of people's understanding of history is often very shallow, the understanding of history and geography is even shallow, even then, when their data mention the former capital of the Yue Kingdom, Langya, they will also write a sentence in passing in the territory of Linyi, Shandong, but in fact, the capital that the Yue Kingdom moved to at that time is obviously located in Qingdao and the territory from the map, and the location is extremely close to the Langya Mountain.

Compared with Linyi, Shandong, this location is obviously closer to the sea, so the process of supervision also proves the familiarity with this route, from the point of view, for the people at that time, overseas exploration was quite difficult, because the objects worth exploring are not as rich as imagined, perhaps the achievements of the north to the outside world are even far more than the south, because they are next to the Liaodong Peninsula, the Korean Peninsula, the eagle and the chicken are also not far away, in this case, It is very likely that the exchanges between the north and these three places have already begun, and even in the early development of these three countries, the people who migrated from the Shandong Peninsula played an extraordinary role, of course, such a statement is now lacking evidence support, but there is no doubt that the development of history is very fast, even in the more ancient Spring and Autumn Period and the Warring States Period, the north did not establish relations with these places, in fact, this probability is already very small in the navigation conditions at that time, However, with the encouragement of the northern regime, the local people quickly participated in overseas exploration.

Otherwise, there would be no depiction of the external regime at that time in history, you must know that this is a foreign place name that appeared in the historical record relatively early, and those that can leave traces in history are generally more able to attract the attention of the imperial court, and yesterday's reaction is often lagging behind, which has not changed even in the 21st century. Therefore, it can be judged that the exchange of people-to-people relations has long been the link between the north and these external places. The record of the official history books has only developed to the point where it has to attract official attention, but this also fully proves that China's early overseas exploration was mainly concentrated in the north, and the reason for this situation is not that the southerners will not use ships - what a serious joke - but because the sea and land exploration in the south is more demanding in terms of natural conditions, and even more at a loss in terms of geographical conditions, so it is impossible to make important discoveries that can appear in the historical record. Under such circumstances, it is also fully proved that China's geopolitical factors have seriously limited China's spirit of exploration in certain fields.

Geopolitical factors seemed a very strange thing at the time, but in the 21st century, almost all problems can be explained, of course, there are some far-fetched problems, but it is undeniable that China's classic agricultural society has been seriously affected by geography.

For example, the rising Mediterranean civilization, to a certain extent, has achieved a geographical advantage, different from the general shape of the Chinese coast protruding to the ocean, the situation of the Mediterranean Sea is just the opposite, it is the protrusion of the sea to the land, it is almost an ocean surrounded by land on all sides, if you ignore Gibraltar, it is not really an important width, maybe it should be called a lake, more appropriate, but it is undeniable that I asked him if it is connected with the Atlantic Ocean, None of this can hinder the fact that Greek civilization swam in this huge bathtub.

Greek civilization is biased towards the east side of the Mediterranean Sea and the Atlantic Ocean estuary, and there is no direct connection, and there is no need for the Atlantic Ocean to support the development of civilization, on the contrary, it is actually far from the second largest ocean in the world that is far from the Pacific Ocean, and it was not used by Europeans until the 11th century, and this user is still the pirates of Northern Europe, not those explorers of Southern Europe, or those powerful countries of Western Europe later, in this case, the development of Greece can only be said to be actively exploring distant lands in the nearby seas, And slowly accumulate the result.

An important reason for the rise of Greek civilization is that it was a small country on land, but it had a wealth of exploration options on the sea, whether it was the Italian peninsula in the west or anywhere else in the east, it formed a fairly good space for development, even Egypt in the south, Asia Minor in the southwest, and played a similar role later.

So their maritime industry developed quite rapidly, and this was only based on the simple democratic system cultivated in the era of their small country and widowed people, and the simple democratic system allowed everyone to have a place to use their talents, so those shipbuilding and various scholars also played a very important role in the marine industry, and at that simple time, people's understanding of knowledge was also quite simple, and even the content of the inquiry itself was quite simple, even the father of geography, It doesn't necessarily mean that you have a strong knowledge base.

This simple and pragmatic style of writing can be said to have laid a solid foundation for the Renaissance and even the beginning of modern science, and after we do not have such a rich practical activity, we have to slowly fall into unjustified meditation outside of boring agricultural activities.

To some extent, this is also determined by geopolitics, and this is precisely far-fetched.

At the very least, it cannot be attributed entirely to differences caused by geography.

In fact, the later Huaxia lawyers could have continued to develop towards the blue civilization, but they decisively gave up on that road, is this also caused by geographical factors?

The stupid Manchu government was the first scourge of this failure, and the Ming governments of Alfbay and Pippi were not entirely innocent, although the opening of the sea in Longqing changed the basic form of foreign relations to a large extent and made the exploration and navigation of the people quickly resumed, but the vast majority of people were obsessed with offshore trade and discarded the ocean trade that had been at the peak of the Song Dynasty, and at that time the spring breeze of the Age of Discovery had already arrived, and the New World had been discovered for fifty or sixty years. The Spaniards had appeared along the coast of China, and they had occupied important transit points along the coast of China to other routes, and in such a situation, the Chinese merchants had to trade with this group of people, and the prices they gave also satisfied the Chinese merchants, how could a group of merchants from silver-poor countries not be interested in the Mexican silver dollar?

This is the misfortune of the times, if it is not the Longqing Emperor but the Zhengde Emperor who implements this policy of opening the sea, maybe there will be a huge change in history, but such an assumption is no longer meaningful.
