In fact, the demise of the Northern Song Dynasty and the economic collapse were also one of the important reasons. The emperor of the Great Song Dynasty first was extremely poor and luxurious, and built Genyue in Tokyo, and then the corrupt officials and corrupt officials moved the treasury grain depot with their hands.

After that, Huizong used troops against the Western Xia for many years, the internal rebellion of the four major Kou, and the rebellion of ethnic minorities in the south, and then the failure of the attack on the Liao State, and then a series of wars and the corruption of the ruling class, so that the treasury tax increase was not enough to maintain.

Cai Jingtong Guan and others simply cut down paper money indiscriminately, Jiaozi credit went bankrupt, floods and droughts occurred frequently in the world, the monarchs and ministers of the Great Song Dynasty were busy with party disputes, and the ethnic minorities in the north continued to move south because of climate problems.

In short, the monarchs and ministers of the Great Song Dynasty are playing and playing off, and a good country is inexplicably gone, and natural disasters and man-made disasters account for half of it, and even man-made disasters are better than natural disasters.

Just like Zhang San's investigation of Hebei and Shandong, it has always been a place of ointment, and it has been the center of national population, finance and taxation in all dynasties, but when it comes to the Northern Song Dynasty, it has become a dilapidated and withered scene.

The reason for all this is the dispute between the three Huihe rivers in the Great Song Dynasty that lasted for 50 years, the Yellow River did not flow north from the time of Huizong, and the Yellow River broke in the eighth year of Renzong's Qingli and ran north, and flowed to the Liao State and the sea in one breath.

The monarchs and ministers of the Great Song Dynasty thought that this would not work, if this entered the sea from the Liao State, then the Liao State was crossing the Yellow River, and directly crossed the river from other countries, so their own Yellow River natural danger would not be gone soon?

So the court launched a fierce party struggle, and finally supported the victory of the party that changed the Yellow River back to its former course, but everyone did not invite a large number of engineers and technicians to study how to do it, but the court pig took it for granted that as long as the gap was plugged, then it could be done.

The result is obviously not done, the day was blocked, the Yellow River broke again that night, and then it was blocked twice, blocked and broken, broken and blocked, and broke again, and finally stopped when Huizong did. This is also the news that Zhang San heard at the beginning of the so-called northward flow of the Yellow River.

The dispute over returning to the river, which lasted for half a century, was nothing more than a matter of fighting for a little right to speak and a little interest.

So far, the Yellow River has broken every year, Hebei often becomes Zeguo, the people of Hebei, ten to five or six, there is no longer the prosperity of the past, and later when Jin destroyed Liao, Tong Guan sent troops from Hebei several ways to be overturned.

Tong Guan ran back to Tokyo and started all over again, but the people of Hebei became a military disaster, first the Great Song Dynasty defeated the army, then the Liao soldiers went south, and then what Guo Yaoshi descended to the Song Dynasty, at that time Youyun and other places had long been plagued by the Jin soldiers.

Therefore, in order to support Guo Yaoshi's three continents to continue to transport grain to the north, Hebei, Shanxi and other places were overdrawn badly, and when the Jin soldiers went south, there was no money and grain to organize troops to resist.

As the second largest financial and tax place in the Great Song Dynasty, Jiangnan first caused the disaster of Huashigang, which caused the people of Jiangnan to complain, and then the Fangla uprising was destroyed again, and the Song army suppressed the rebellion and caused another scourge, and when it returned to the hands of the imperial court, it became a rotten land.

There is also the Huai River valley in such a place, Wang Qing has been plagued again, so the Great Song Dynasty is full of smoke and fatigue from scourge, and the court pig Gong really only knows that the party is the same as the other, corrupt and bribe-taking, and bent to welcome the emperor.

And this time Zhang San launched the Great Song Dynasty campaign to expose some problems in advance, first of all, the army's combat effectiveness is underneath, not to mention that Zhang San used science and technology to invent in the early stage, that is, in the later stage, the Great Song Dynasty Forbidden Army was also easily overturned.

The Great Song Dynasty lost the 500,000 forbidden troops, basically the world was empty, and the defense of the capital was almost empty, Zhang San estimated that if he had 50,000 cavalry, he would be able to directly enter Bianliang, so Zhang San felt that after the war, the Great Song Dynasty would definitely immediately go all out to recruit troops and build ships to do a good job of defense, so as to prevent the outbreak of the next crisis.

But the Great Song Dynasty did not do this, the first to restore the transportation of Huashigang, the first ship to be built is the ship to transport Huashi, I don't think about how to appease the people, first think about how to collect taxes, the population of Jiangnan was removed by Zhang San about seventy percent.

The rest were either really reluctant to go, or they ran away in advance, and then ran back after the end of the war, and during this time I heard that there were lands in Jiangnan to plant displaced people who came back from all over the country one after another.

The reason why the homeless people become homeless people is that they can't survive, because they have just rented the land from the landlord's house, and before they have time to plant crops, you will collect taxes here, so the Jiangnan area is full of complaints.

Moreover, in addition to the recruitment of 200,000 new soldiers in Tokyo, the Great Song Dynasty did not recruit soldiers on a large scale in other places, and it seems that the Great Song Dynasty did not plan to restore the national military strength at one time, and after the shipyards in various places resumed the manufacture of Huashigang ships, they did not go all out to build warships.

The court is also discussing the issue of Western Xia, it seems that everyone has forgotten the war in the south, the Liao State and the Western Xia are friendly, and now the Western Xia is hanging, so the Great Song Dynasty is arguing whether to continue to fight the Western Xia.

There is also the issue of raising taxes, it turns out that the monarchs of the Great Song Dynasty do not want to strengthen the defense of the south, but they have no money, so everyone is discussing raising taxes and increasing the types of monopoly items, raising the price of salt, and so on.

Last year, Cai Jing and others just started a tea monopoly, and this year they want to incorporate more substances into the monopoly system, because with the rise of Zhang San, there are many novelties, such as Jiaoyou monopoly.

This Jiao oil is whale oil, Ryukyu now almost monopolizes the high-end lamp oil market in the Great Song Dynasty, making the original inconspicuous commodity into the public's field of vision, Ryukyu Jiao oil is easy to use and cheap, since it makes money, it must be monopolized by the imperial court.

Therefore, the court is studying the inclusion of Jiao oil in the franchise and then selling it at a higher price, Zhang San is speechless about this, and there are other cans, soap, glass, and so on, and these things are all wanted to be franchised by the Great Song Dynasty.

As for raising the price of salt to crack down on illegal salt, it is also related to Ryukyu, after the introduction of the salt drying method in Ryukyu, after two years of development, the technology is becoming more and more mature, and the price of salt has been reduced again, so now the coastal areas are selling Ryukyu private salt.

The most obvious change was that the salt tax revenue of the Great Song Dynasty fell by nearly one-third, and in order to cope with this change, the idea of the Great Song Dynasty officials was to crack down on illegal salt and raise the price of salt.

In fact, according to normal logic, shouldn't the price be reduced if you can't sell your own things? But the logic of monopoly is not to let others sell, just sell yourself, so that you will not make money?

Zhang San is against this, because this will violate the interests of the Ryukyus and reduce the sales of Ryukyu goods, but people discuss it by themselves behind closed doors, and Zhang San has nothing to do, so he can't send an ambassador to negotiate a free trade agreement, right?

So Zhang San plans to wait for Da Song to take actual action and deal with it, after all, if he talks about it now, it is obvious that telling the other party that he has planted a spy in their court will also provoke Da Song's nervous nerves, Zhang San still hopes that he can develop in a low-key manner.
