Su You couldn't help but roll his eyes secretly, to put it lightly, how many officials in the Song Dynasty could do it like you, who didn't own any property and only brought a bird with you? How could you say harsh words to a powerful family? Anyway, Su You had gone from Chukelong to

Now for three and a half years, you are the only one I have seen!

We ate river delicacies along the way and the boat rocked until we arrived at Dujiangyan.

Dujiangyan is now under the jurisdiction of the Yongkang Army, which is a force of about 1,500 people.

Speaking of the army of the Song Dynasty, it is another painful problem.

There was a lot of commotion on the Internet in later generations. The Song Dynasty raised so many troops, but they were beaten by the Xixia and Liao Kingdoms. Did they all raise a bunch of pigs?

After Su You studied this issue himself, he understood that they were not pigs, but cows, and most of them were cows.

In the fifth year of Qingli's reign, Ding Du recorded five chapters on the army, and Qi of the Song Dynasty wrote a preface to it: There are four types of troops: one is the forbidden army, and the three divisions on horseback and foot in front of the palace are under the command of the army.

Either they are treading water, they are attacking ships, they are riding suddenly, or they are throwing rocks to attack and stab them. When they are at home, they will defend the town, and when they leave, they will be on guard;

The second is the Xiang soldiers, who are under the jurisdiction of various states and recruited by those who are strong and brave. The world has been settled and does not rely much on soldiers. Only the barbarians on the border are always hoarding with the forbidden soldiers, specializing in serving labor, and there are also updates at times;

The third is to serve soldiers. The group has a commander and a subordinate. Those who wander around and are lazy can enter. If it is a herdsman, if it is a canal, if it is a treasury, if it is a craftsmanship, it is dedicated to one thing, and there is no change in the old place. Every army has a quota

, there is a camp, a permanent home, and horizontal gifts;

The fourth is the militia. When the farmers are strong and the villagers are registered, they will be numbered according to the size of the villages and counties. If there are tribes and no camp walls, those who are missing will be supplemented. They will be read every year. Unless the army is prosperous, it cannot be practiced.

To put it bluntly, the Song Dynasty's army is said to have more than one million, but in fact there are three types of troops, which are almost all in name only.

The latter types are not concerned with physical fitness. They are often a disaster relief measure. They gather young and strong victims to prevent them from rebelling. They can also solve the labor reform problem of some prisoners. To put it bluntly, they are maintained by the state.

Idle people.

It is conceivable that these people are very motivated to work, so they cannot produce any social benefits, let alone their combat effectiveness. They can be said to be a heavy burden on the country.

This is the essence of the concept of "redundant soldiers" in the Song Dynasty. Most of the soldiers here are not troops as understood by later generations.

According to this calculation, all courier guys in future generations should be considered soldiers!

The only armies that could really fight in the Song Dynasty were the Upper Fourth Army of the Forbidden Army and some Xiang armies in Hebei and Shaanxi that had long been in confrontation with the Xixia and Liao Kingdoms.

For the rest, it would be more appropriate to call them construction corps or even refugee camps.

After excluding these, the real combat strength of the Renzong Dynasty was about 800,000 at its peak, and then it was reduced through hard work to about 700,000 today.

This is the number on the military register. Not to mention how many false numbers there are, even if they are all taken into account, the combat effectiveness of the Forbidden Army will still be reduced again.

Because of Zhao and Song's inherent deficiencies, all major geographical channels were under the control of others and they were still in a condescending position, resulting in no danger to defend.

Therefore, 300,000 of the Forbidden Army were concentrated around the capital to protect the center, while the rest were scattered on the front lines at various key points.

In doing so, firstly, they learned the lessons of the Chanyuan Alliance and used a large number of troops to defend the capital; secondly, they maintained a balance with the border troops to intimidate the border generals.

In fact, there are very few combat opportunities for the Imperial Guards in the capital. They have been slacking off for a long time. In addition to the vacant positions, many of those who are not vacant have become long-term workers for the high officials.

Okay, the Forbidden Army troops that are actually used to defend against foreign enemies are just like the loan provisions of Sitong Company. They are split in half, which leaves about 300,000 yuan.

Looking at the foreign enemies, Xixia has more than 300,000 troops, and the Liao regular army has more than 300,000 troops, as well as a large number of servants. Moreover, most of the more than 300,000 troops in these two countries are cavalry.

With the conscience of heaven and earth, Su You sincerely felt that it was not that the Song Dynasty army was incompetent. It was... what the hell was this that made it look like this?

Except for the capital and the northern border, the rest of the Song Dynasty was almost a land without soldiers. No wonder that once the front line was penetrated, people could drive straight into the capital.

Every time he thought about these problems, Su You felt his liver hurt.

Lao Yang, Lao Zhong, Lao Zhe, you can still carry on for more than a hundred years like this, thank you for your hard work!

Back to gossip, this situation has reached Sichuan, that is, there are currently five Xiang armies on the 4th Sichuan Gorge, with a strength of 20,000.

Among them, the Yongkang Army is such a local team with a glorious tradition. Their mission is to "regulate Dujiangyan every year, use stone snakes to cut the river to contain the water, and to irrigate several county fields."

The entire Sichuan Gorge Fourth Road has to rely on five "armies" that carry rocks, dig salt, and engage in logistics to control the situation!

This is the reason why Su You suggested to Zhang Fangping to concentrate the training of rural archers in the fields. With such a huge family property, there must be a team that is a little bit more eye-catching to watch, right?

…

The Yongkang military commander's surname was Cao. He came from the central government at any rate. He was under the command of the inner palace and was in the seventh rank of martial arts.

The boy was smart and worked hard to get closer to the civil servants. Before he came, he asked Mei Yaochen for a poem: "Iron Cong is golden and guarding the city of Shu when he was young. The city of Shu is near the ancient river and is offshore. Li Liang is cutting off the shore, which is beneficial.

Soon after, we not only avoided the damage caused by foaming water, but also irrigated the fields. This is suitable for hundreds of people, so we left the temple to offer sacrifices and wine. We should act with caution and be the leader of the government."

Mei Yaochen and Zhao Bian have a good friend in common, Zhang Xian, who is "the clouds break and the moon comes, and the flowers make shadows", "the delicate and lazy, the curtains roll with the shadows of flowers", "the willow paths are deserted, and the catkins fly without shadows"

Zhang Sanying.

Zhang later lived to be eighty-nine, and he stayed for such a long time that Su Shi became a good friend with him. Su Shi also laughed at him as "a pear tree weighs down a begonia".

With this relationship, Cao Zhijun took the judge to pick up the old man Zhao and handed him the poem, which made it easier to talk.

Cao Zhijun was quite familiar with the business and knew the allusions of Guankou very well. Old man Zhao was leading Su You while Cao Zhijun was explaining it, so he was able to pick it up easily.

The Dujiangyan Irrigation Project is miraculous not only because of human power, but also because of God's will.

The Minjiang River has a high potential. In fact, it is similar to the Yellow River in Kaifeng. It is a hanging river on the edge of the entire Chengdu Plain.

Once this river encounters a flood, the southern part of the Chengdu Plain will be flooded. Once it dries up, the northern part of the Chengdu Plain will be extremely dry.

Li Bing controlled the water and traveled up the river. He discovered that the Yulei Mountain on the east bank of the Minjiang River was majestic and extremely difficult to excavate. It was almost an impossible project in the Qin Dynasty.

But when he arrived at Dujiangyan, he found that the mountain suddenly narrowed here. The narrowest stone wall was only 40 meters!

This is God's will. As long as this point is dug through, the water potential of the Minjiang River can be divided into two, and the upper and lower parts will be balanced. From now on, the Chengdu Plain will no longer suffer from droughts and floods!

Once you find this point, all that's left is manpower.

"Historical Records of Rivers and Canals" records that "Shu guards cut the ice off the pile to avoid the harm of foam water", because "the cliff is steep and dangerous and cannot be drilled, so Li Bing burned it with firewood".

This is the famous Baopingkou.

After the Baopingkou water diversion project was completed, although it played a role in diversion and irrigation, due to the high terrain in the east of the river, it was difficult for the river water to flow into Baopingkou. Li Bing and his son led a group to build water diversion projects in the upper reaches of the Minjiang River and the center of the river not far from Yulei Mountain.

Starting from the water diversion weir.

Large bamboo cages filled with pebbles were placed in the middle of the river to form a long and narrow island, shaped like a fish's mouth. The Minjiang River flows through the fish's mouth and is divided into two rivers, the inner and outer rivers.

There are six outer rivers and four inner rivers. The outer river still follows the original flow, and the inner river is artificially constructed to raise the water level and flows into the Chengdu Plain through Baopingkou.

In order to further divert floods and reduce disasters, a spillway was built between the diversion weir and Lidui to flow into the outer river to ensure that there is no disaster in the inner river.

The front part of the spillway is a big bend, where the river water forms a circulation, sediments, and floating objects are carried into the outer river by the current, so that the inner river and the Baopingkou waterway will not be blocked, so it is named "Feishayan".

The ancients' scientific application of the principle of gyrating flow.

In the Dujiangyan canal head project, the positions, heights and lengths of the Baopingkou, Feisha Weir and herringbone embankments are perfectly matched and cleverly coordinated to limit flow and discharge sand during floods, and to store high water levels during dry periods.

The ancient bamboo cage structure of the weir is not stable under the impact of the rapids of the Minjiang River, and the inner river channel cannot avoid siltation despite its sand drainage mechanism. Therefore, the Dujiangyan weir needs to be repaired regularly to make it operate effectively.

By the time of the Song Dynasty, a system of annual repairs had been established, which was called "Chuang Tao".
