And since the Second Expedition to Goguryeo, which originally had the upper hand, failed to rebel in the rear because of Yang Xuangan, the situation of the Great Sui became out of control, with land annexation, overpopulation, the disadvantages of the gate valves, and the stupid greed of the officials...... All kinds of contradictions and problems that have accumulated over the past few years have erupted one after another, and the whole country is in a mess and is becoming more and more dilapidated. To make matters worse, the chaos has led to more problems and bigger hidden dangers:

For example, Li Yuan, Luo Yi and other local military leaders saw that the central government was declining, and their loyalty was becoming weaker and weaker, and they began to disobey the orders of the imperial court, and even set up their own mountains. By the time Yang Guang tried to conquer Goguryeo for the fourth time, the world was already in turmoil, and officials from all over the country secretly resisted it, and finally the plan to conquer Liao ended without a hitch, which shows that the Great Sui was in fact powerless to capture Goguryeo. When Yang Guang found that he was helpless against this culprit who disobeyed himself, caused him to work hard and lost money, and lost face, the annoyance and depression in his heart can be imagined.

Yang Guang had a smooth ride in the first half of his life, and was respected by the people of the world, and when he was full of ambition, he conquered Goguryeo, intending to add icing on the cake, thinking that he could win as lightly as he could destroy the withering and decaying, but because of his overconfidence, he underestimated the enemy and returned with a fiasco, which inevitably made Yang Guang feel greatly disappointed in martial arts. Eager to wash away his shame, regain the prestige of the Great Sui, subdue the surrounding tribes, and rebuild his reputation, he hurriedly launched two more large-scale attacks on Goguryeo, but each time they failed to return. And since the Second Expedition to Goguryeo, which originally had the upper hand, failed to rebel in the rear because of Yang Xuangan, the situation of the Great Sui became out of control, with land annexation, overpopulation, the disadvantages of the gate valves, and the stupid greed of the officials...... All kinds of contradictions and problems that have accumulated over the past few years have erupted one after another, and the whole country is in a mess and is becoming more and more dilapidated.

To make matters worse, the chaos has led to more problems and greater hidden dangers: some local military leaders, such as Li Yuan and Luo Yi, saw that the central government was declining, and their loyalty was becoming weaker and weaker, and they began to obey the orders of the imperial court, and even set up their own mountains. By the time Yang Guang tried to conquer Goguryeo for the fourth time, the world was already in turmoil, and officials from all over the country secretly resisted it, and finally the plan to conquer Liao ended without a hitch, which shows that the Great Sui was in fact powerless to capture Goguryeo. When Yang Guang found that he was helpless against this culprit who disobeyed himself, caused him to work hard and lost money, and lost face, the annoyance and depression in his heart can be imagined. Only when there is enough food and clothing can we know honor and disgrace. Most of the people don't care too much about the dignity of the country, the expansion of the territory, and the four provinces, and they don't think about the big projects that cost the people and money and the significance of the long-term peace and stability of foreign wars in the future. Therefore, in the years of requisition and painful life, the people's feelings for Emperor Yang of Sui have changed from worship to dissatisfaction, which has always dealt a great blow to Yang Guang, who has always been confident and strong. Especially seeing that the Great Sui Dynasty, which he built single-handedly and was thriving not long ago, has collapsed, this huge contrast makes the proud Yang Guang unable to accept it at all, this emperor who has always been full of confidence collapsed all of a sudden, his spirit is not as good as before, and the whole person does not look as optimistic and ambitious as before, and sometimes even secretly cries where others can't see, like a wronged child. At this time, Emperor Yang of the Sui Dynasty also tried to make great efforts, eliminate the accumulated evils, and reorganize the atmosphere, but when he sat on the dragon chair and wanted to do something, he found that this empire had long been controlled by various lords and nobles, and there had already been a complete set of processes for exploiting the people and illegally grabbing wealth, forming a complete chain, even if he was the emperor, he was powerless to go against this huge network of interests. Therefore, although many of his reform decrees were quite good, they could not be implemented at all when most of the executors disobeyed them, and some of them were even distorted into the chaos of the people, and the victims would attribute their dissatisfaction to the emperor who issued the decree...... The situation in the world is getting more and more chaotic, but Yang Guang wants to be weak, watching the building collapse, but he can't do anything, he is angry and helpless, and his once vigorous spirit and enterprising spirit are getting weaker and weaker, and finally his ambition is gone, and he completely gives up his efforts to save the empire. At this time, the weakness in his bones began to prevail, leading him to escape from reality, no longer turning a blind eye to corrupt officials and corrupt officials exploiting the people, and no longer caring about the rebels all over the land, and even began to deceive himself and whitewash the peace. From the bottom of his bones, Yang Guang is a person who is not stubborn enough, and he is not ruthless enough to others and himself. When the wind is smooth, he will work harder and harder, and he can do better and better, and he will appear eloquent, shrewd and wise; But as soon as they encounter difficulties, they will be in chaos, retreat and evade, and sit back and watch the situation get worse and worse. In the past three or four years, Liukou has long ceased to be a problem of scabies, but Pei Ju, Pei Yun, Yu Wenshu, Yu Shiji, Zheng Shanguo, Feng Deyi and other capable ministers and contemporary celebrities have always insisted that Liukou will be extinguished one day later, trying their best to cover up the chaos. As the wise and martial Emperor of the Great Sui, Yang Guang himself also tried his best to decorate the illusion of this prosperous era, so he belittled the truth-telling old Nayan Su Wei, Zhishu Yu Shi Weiyun, and Zhao Xiaocai, the secretary of the military department, on the charge of "alarmism", and even put Ren Zong, the captain of Jianjie, who was playing at the top of the ranks, in court, and no one dared to speak for the country again. Yang Guang's temperament is becoming more and more distorted under pressure, and he seems to have a dual personality. This man, who has always seemed wise and calm, has become soft-hearted, indecisive, and does not distinguish between public and private, and his spirit is sometimes good and bad, and his emotions are volatile, sometimes he can reproduce his previous wisdom, and sometimes he is confused and confused; Sometimes they are decisive and stubborn, sometimes they listen to and believe partially, and they are chaotic; Sometimes he is a corporal, and sometimes he is jealous...... He was quickly surrounded by a group of sycophants who would only reap benefits and would not do practical things, so the correct national policy could not be adhered to, but absurd orders were constantly issued under the bewitchment of these villains. Just when the Great Sui had clearly collapsed, he failed to actively remedy it, but let it go, blindly evaded, and even hid in Jiang in 616 without asking about political affairs, and handed over this mess to Yang Tong, the king of Yue, and Duan Da, who stayed in Luoyang. After arriving in Yangzhou, Yang Guang saw that the situation was becoming more and more chaotic, and he was even more disheartened and irritable all day long. At that time, the national politics were erosive, and the urgent documents sent from all over the country were like snowflakes, but he didn't bother to give instructions, to be precise, he didn't dare to read these bad news, and he didn't want to think about these troubled things, so he either dragged it out, or pushed it all to his subordinates Pei Ju and Yu Shiji. Yang Guang didn't know that these people were only loyal to the interests of their own family and only cared about making money, but he had no intention of caring about these anymore, and just wanted to escape the troubles in front of him as soon as possible. Yang Guang did not ask about state affairs in the later period, not because he was lazy by nature and indulged in pleasure as many people in later generations misunderstood. It can be seen from his previous ambition and active work that Yang Guang is not the kind of hedonistic king, but he has suffered too heavy blows in successive defeats, the deterioration of the situation and the despair of being unable to save the crisis, and has been crushed by a series of bad news that followed, so that his temperament has changed greatly, and in a short period of time he has faded from a generation of British lords to a dumb and incompetent king. In fact, his transformation is not surprising, the more ambitious people are, the more completely they will fall to the ground after the collapse. His subsequent behavior of covering his ears and stealing the bell not only reflected his weakness of temperament, but also showed that he had high expectations of himself. If he had always been a mediocre emperor like Liu Chan who only knew pleasure, he would not have been completely knocked down by the huge contrast between his wishes and reality, and he would not even dare to face reality. At this time, Emperor Yang of the Sui Dynasty had lost confidence and fighting spirit in governing the country well, so he was not willing to hear any bad news at all, and even deceived himself, conniving at his subordinates to report good news but not bad news, and ordered the important ministers of the empire to classify the folds and folds, and only pick up happy news and send it to the palace, which can be seen in his evasive mentality. And since he was only willing to give instructions on a few pleasant notes, and ignored all the troubles, then his life was naturally idle. In order to eliminate the strong sense of loss and the huge pressure on government affairs, and in order to escape the reality that he does not want to face, Yang Guang never leaves his glass all day long, ** wine, drunk and dreaming of death in Shengge. At this time, Emperor Yang of the Sui Dynasty had completely lost the sense of responsibility that an emperor should have, and when the country's ills broke out, he failed to take any effective measures to turn the tide, delaying the collapse of the Sui Dynasty, and began to evade lazy government. Although there were many reasons for the sharp deterioration of the late Sui Dynasty, Yang Guang's collapse and escapism undoubtedly accelerated the collapse of the Great Sui. Of course, under the internal and external troubles at that time, he was really powerless to make it before the unbreakable interests and selfishness of the small group of the gate valve clan. If he decisively carries out a major blood change and removes those officials who only know how to accumulate wealth, then the gate lords will inevitably break out a strong backlash, and the Great Sui may be immediately torn apart. Moreover, the removal of most of the vassals around him is tantamount to admitting to the whole world that the government of the Great Sui Dynasty has been eroded to the point of being out of control. In fact, most emperors are not only far inferior to Yang Guangxiong in the early stage of his reign, but also diligent in governing the country, even compared to Yang Guang, who never left his hand before the death of the country. It's also just an occasional big deal, and most of the time it's not in ** enjoyment? It's just that because the country is still stable, the foreign enemy is not strong, there is no trouble with the gate valve, and the vassals are loyal and powerful, so they will not lose the country if they have fun for a lifetime, and they still don't have to bear any historical infamy, and they may even be praised as a generation of Ming Jun. Emperor Wen and Emperor Jing traveled every day, and they were praised by later generations for their wisdom of "ruling by doing nothing". This is actually the same as doing things in the unit, people who actively take care of things and do things will naturally gain fame and fortune, but if they don't do it well, they are not as good as those who don't do anything.
