The knowledge you get from paper is always shallow, and you must practice it yourself to know it.

If you don’t do some things yourself, you really don’t know what strange difficulties will suddenly appear at the execution level.

For example, if Li Su was allowed to sit in the yamen in Chengdu and imagine that "the reason why Han people's civilized development of the Jinsha River Basin was slow to develop from the late Han Dynasty to the Tang and Song Dynasties", he would probably only think that there were constraints on technical and commercial interests.

Even if he wants to break his head, he will not think that "the Han people think that the Jinsha River is just a trivial poisonous water of the Nanman River and has no value for in-depth exploration" can also be one of the important reasons.

Because before coming, the reason why Li Su was confident in his plan and dared to resist the public and promised to Liu Bei was because he knew some relevant history:

Later, in the Ming and Qing dynasties, with the development of the southwestern Yishi's transformation of land and land, the shipping in the middle and upper reaches of the Yangtze River, after a little remediation, it could reach Laojun Beach, Qiaojia County, Zhaotong, Yunnan without any technical difficulty. The technical equipment and mobilization capabilities of the feudal natural economy can be solved.

Li Su could do something that people in the Ming Dynasty could do, and Li Su could definitely do it even if he had a little technical skill.

As for the navigation from Zhaotong Laojun Beach, Li Su had never thought about it, because he had read the history of the War of Resistance Against Japan and knew that even in the 1930s, modern engineering technology could not overcome such projects.

On the eve of the Anti-Japanese War, the troops from the Pro-Side passed by Laojun Beach in the Long March and could not cross the Jinsha River here. As for the troops of local warlords in the southwest, during the Anti-Japanese War, they originally wanted to develop shipping above Laojun Beach to meet U.S. aid materials transported from Yunnan to Sichuan and achieve full water transportation from Yunnan to Sichuan, but they also failed.

In an era when even such awesome projects of the Yunnan-Burma Highway were built, Laojuntan shipping could not pass. It would rather be transported on the east line of Guizhou to "twenty-four turns" to Chongqing.

Li Su doesn't have a map editor, so he won't waste his energy.

However, after personally going deep into the front line and conducting research in the masses, Li Su became more confident in his plan: since he knew that the crux of the problem lies in the hearts of the people and not in the technology, it would be easy to solve it.

After half a month, Li Su summarized a few experiences in his mind: "It turns out that it was not the people from the Tang and Song dynasties who were not good at technology, but they had no motivation to come. The ancients' desire to explore geography was so low, and they had no desire to conquer the outside world at all, so they knew that the inner husband was.

No wonder Xu Xiake traveled all over the country during the Ming Dynasty and realized that "Minjiang is not the main source of the Yangtze River", but Xu Xiake could not verify how far the main source of the Yangtze River was.

It was also basically starting from Xu Xiake that later talents valued the direct development of the Southwest Yi. In the eyes of Han civilization, the civilizations in the Yangtze River Basin are part of China. How can they be regarded as an unconquered place that is not worthy of conquest?”

It does not attach importance to geographical development, lacks the spirit of exploration, and harms people. Since Li Su has come, of course, he should take advantage of his name as knowing destiny and write external exploration and adventure into the cultural spirit.

At this moment, Li Su was thinking about not only developing Yunnan's local specialties and agate jade. This is a national spirit issue of major issues. Why not promote it?

...

Unfortunately, because Li Su was weak and unfair, even though he was determined to personally stabilize the morale of the army and insisted on exploring, his inspection journey was only more than a hundred miles south of Tanglang County, and he had to turn back.

That place is roughly equivalent to Qiaojia in Zhaotong in later generations, and between Huize counties, because after passing Qiaojia Laojun Beach, it is impossible to take a boat upstream.

Moreover, after passing the southern border of Tanglang, the two banks of the Yangtze River belong to Yueli County and Jianning County respectively. A hundred miles upstream, the southern bank enters Yongchang County from Jianning County.

Liu Bei's current sphere of influence only controls Zhuti County, which was divided into Jianwei County, so it is very dangerous after leaving the Zhuti Realm, and they are all enemy-occupied areas that are not convinced by Wang Hua.

But Li Su still sent a small expedition team to continue to go upstream on land to make geographical discoveries, and promised that everyone who came back alive would be upgraded. Before leaving, he would give his family an additional 30 mu of Yongyetian, a garrison site along the Lushui coast, as a settlement fee.

There must be brave men under the heavy reward. There is really a team of dozens of people who, led by a village chief, brought enough dry food and herbs to continue to move forward, drawing along the way. Li Su asked them to walk at least 500 miles along the river to the unmanned land.

There is no need to do it, because as long as you walk another 500 miles, the length of the Lu River that has been discovered is longer than that of the Minjiang River, which can prove that this is the source.

At the same time, Li Su knew that walking two or three hundred miles forward was about the junction of Yueli County and Yongchang County, which was roughly the Panzhihua area in later generations. Walking three hundred miles forward, you would leave the border of Yongchang County and enter a region that had no Han civilized throne, which was roughly equivalent to Lijiang, Yunnan in later generations.

Moreover, before arriving in Lijiang, the Yangtze River will turn north, which is enough to prove that the Lu River does not come from the poisonous water from the Southern Barbarians, but from the orthodox snow-capped mountains of Kunlun in the West.

Adding these materials into them is enough to completely stabilize the hearts of developers.

Li Su made an appointment with the expedition team for fifteen days, and he would stay in Zhuti County to continue his inspection and supervision work, and would not even return to Chengdu during the New Year. If the expedition team has not returned after fifteen days, then report to Guoyuan.

The expedition team was lucky. On the way, except for being bitten by poisonous insects and snakes, they died of illness and ate a few by the Manchus in Daliangshan. The others came back alive and brought Li Suyou's hydrological and geographical information.

Li Su added generous pensions to the victims, and in the future, he wrote it into the preface, listed as "a contributor to this book". The living promotion rewards.

...

When the expedition team returned, most of the waterway rectification work on Guoyuan was completed.

Seeing that Governor Li was beating his prophecy and command came true one by one, Guoyuan was also full of admiration and couldn't help but praise him:

"It's all up to the governor to disagree with the public and not be moved by the rumors of the shaken people. Our army was able to leave Lushui, which was regarded as forbidden by the barbarians, and go directly to Tanglang County. In the future, we will directly attack Muma, Gu Chang, and subdue Jianning Man. Wouldn't it be like a god's help, and the divine weapons descended from the sky!"

Guoyuan's words are definitely not bragging, because Li Su's rectification of shipping is not only of commercial development but also of sudden military attacks.

Since ancient times, people went to Jianning County, and walked from the Jade Road to Yangguanshui to Zhuti County. Then, from Zhuti County to the south, it was land. They had to pass through Cunju and Wei County to reach the Kunming Basin around Dianchi Lake.

It is precisely because this road is very important in history that in history, Liu Bei's surrendered Governor's Office was all chosen in Wei County, Jianning County. When Zhuge Liang attacked Meng Huo, Meng Huo wanted to guard the dangerous mountain pass, and also used Wei County as the gateway to southern Yunnan to guard the troops.

After Li Su opened up the Lushui shipping, in the future, he would go around the back and descend into the sky without having to pass through Wei County and enter the Kunming Basin directly. The surprise attack effect was definitely better than Deng Ai's smuggling through Yinping and blocking Jiang Wei in the Jiange Road.

Of course, Guoyuan still doesn't know where to go around Tushui, because no one has walked this road since ancient times. But this does not prevent him from admiring Governor Li's courage to go around.

But now everything needs to be kept secret. Anyway, there are no barbarians to stop the river here, and I don’t know what they are doing, nor will I associate it with the military keys hundreds of miles away. The barbarians do not have this IQ.

As long as the Han army officials who built the river kept their motives secretly and kept it confidential until the autumn harvest, it would not be a problem. Anyway, Guoyuan himself knew that it must be kept confidential.

Li Su also seems very modest in his praise for Guoyuan:

"Don't praise too much. We are just trying to promote profit with the people. It is better to teach people how to fish than to teach people. To make the Southwest Yi Chinese a Chinese, the key is to make a living, learn to produce the needs of the Han people, and communicate whether they have enough food and clothing.

Once they have to do business with the Han people to live well, ghosts will rebel and become independent, and they can be supplemented by being appointed as officials and education in the future. This year we are just the first step, and I should leave. You can do the things here by yourself. If you have uncertain messengers to Chengdu."

"The subordinates obeyed the order." Guoyuan made a promise very conscientiously, and then sent a boat downstream to send Li Su back.

On the way back, Li Su did not forget to inspect the work and gave guidance from time to time.

It’s true that Guoyuan has accumulated work experience last year, and he just moved it to Lushui by force, and he was really uncomfortable. At the beginning, he made several jokes. In the past few days of his return trip, Guoyuan often reviewed Li Su.

For example, when they returned to a newly established county garrison site at the intersection of Tushui and Lushui, the people complained and asked Guoyuan to exempt the rabbit tax, saying that the method he taught was useless.

"What's going on? Go and find out the situation." Li Su was very Qingtian and took some time to inquire about these disputes.

So a representative of the village residents came to complain: "Governor, the lieutenant asked us to release rabbits for free. When winter is the coldest, we set up traps to catch them and make dried rabbits. We will send them to every ten rabbits. After winter, fifty rabbit jerky meat will be collected as tax subsidies for military rations.

But we put the trap and the free-range rabbits cannot be caught, or they have caught very few, which is not enough to pay taxes. We have not left a bite of meat!"

Li Su hurriedly went over to investigate in depth and found out the crux of the problem. He couldn't help but laugh: "Guoyuan! Are you a rubber squid? The trick I used in Daba Mountain, can you directly apply it to Daliang Mountain? This is not the same thing at all!

Daba Mountain is close to the Qinling Mountains, and it is still north. It will be covered with heavy snow in winter! Rabbits placed in the wild can’t find food, so they will be caught by the little carrot bait from the villagers. Daliang Mountain is at least one thousand miles south of Daba Mountain. How much hotter is the weather?

The mountains are closed without snowing in winter, and of course the rabbits you released cannot be caught! You don’t even understand whether it snows here in winter, so you dare to raise rabbits directly? Forget it, the account of the rabbit’s losses is recorded in the government and recorded separately, and the people cannot bear it. If you have lush shrubs on the hillside, you should raise goats. It is better to have rabbits running than sheep."

Guoyuan was quite ashamed: "I came in a hurry, so I couldn't make any research."

Li Su: "Just pay attention next time. Don't make the same mistakes a second time. Write down the lessons and learn from other colleagues and subordinates. This time, time is also tight, so I won't blame you."

Li Su knows that he should focus on the big and let go of the small. For setting up unreasonable KPIs, he should reduce the exemption of subordinates at the end of the year, so that everyone's morale will rise.

Although he gave up the rabbit's income and changed it to a goat, Li Su found many problems during the run-in period during the return trip in the following days.

For example, when Li Su walked to Xindao County and was about to return to Wudao and leave the mountainous area, another group of people came to complain, saying that the breeding sheep distributed by the military farming officials were harmed by wild animals, and they were all built fences and sheep pens built according to the construction regulations required by the military farming officials, but they were still broken through by the beasts, killing a few sheep, and the rest also scattered and ran away a lot, asking the government to give up the tax reduction in retrospective losses.

This small matter should not be handled by Li Su, but it is still necessary to inspect it once or twice occasionally and evaluate systemic risks.

Li Su set aside half a day to inspect the farm site. As a result, after arriving at the place, he saw that the sheep pen was very solid and was built with Qiongzhu.

Qiongzhu is a bamboo specialty of South China. Because the plants in tropical rainforests grow taller, the best Qiongzhu bamboo joints can be more than one meter away from the bamboo joints, which is very solid. The cane made can make no bamboo joints visible on the entire stick. Therefore, the "Qiong bamboo stick" has been one of the foreign trade flagship products of the Southwest Yi since ancient times.

Even the thick fence made of Qiongzhu was actually broken through by fierce beasts. It seems that the villagers in the military farm should not blame the poor management of the villages.

But Guoyuan just made a fool of himself in front of the governor two days ago. He was a little unwilling to give up and wanted to isolate several villagers to question: "Who knows if there were loopholes here when you were repairing, or if you cut open the fence with a sharp blade, put wolves and kill sheep, and wanted to take profits from chaos and deceive the fat sheep from the government!"

The representative of the village was speechless, and in the end, a villager who was familiar with local geography came out to appeal and complain: "We cannot think of such a crooked mind, but the damage of this sheep pen was definitely not cut by a wolf or a sharp blade. If it was injured by a sharp blade, many fragments of bamboo fences would be scattered, and the fractures would not be so staggered.

Now there are not even fragments left. I am afraid it is not because of the iron-eating beasts, the specialty here! Iron-eating beasts can even eat Qiong bamboos. In the cold winter, there is no bamboo season. If there is a iron-eating beast, they will go down the mountain to eat fences and then break the fence to eat sheep. I want to tell me that you are not teaching the way to persuade people to raise sheep.

Either organize the people to hunt and eat iron beasts, or use tender bamboos to circle another circle, put one or two lambs that feed monsters, and winter bamboo shoots inside. In this way, when the beasts go down the mountain, they will probably eat small circles of tender bamboos and lambs, and winter bamboo shoots. When they are full, they will let go of others. You will not raise sheep in this southern middle place at all, what does it have to do with us!"

It can be seen that the person who spoke was also a local native, so he did not respect the officials very much. He was afraid of Guoyuan, an outsider, who dared to speak directly, and maybe he was prepared to "if he offends the government, he would run away again to become a savage in the mountains."

However, after listening to it by the side, Li Su realized very fairly that Guoyuan might have made another mistake of not understanding the local situation.

Li Su touched her beard and thought for a while, and asked, "What you said is black and white? That is, the body is white, the limbs and ears are black?"

Qu Tunmin heard that when he decided to make the decision for him, his eyes lit up: "The governor is so knowledgeable that he even knows the iron-eating beast that is rare among us locals. This is true. If the governor wants to, we can catch it with the sheep's blood in the future."

Li Su nodded: "That's right, they shouldn't have lie. Guoyuan immediately asked the sheep-raising residents nearby to rectify according to what they said. Sun Tzu said: Those who are capable but the king won, and we must use professional people to do professional things. How to implement farming in the local area? First, we must listen to the opinions of the locals. I'm leaving, and you can think about it carefully in the future."

Guoyuan was quite ashamed: "I was negligent, thank you for your advice."

Li Su also knew that these were all small problems in the development process, so he did not blame him. Two days later, he brought the Nanman specialty jade agate donated by Pang Xi, and the two beasts given by Guoyuan as evidence, and returned to Chengdu from the road to Wudao.

After the autumn harvest, when you conquer the southern barbarians, let’s check the results.
