After Yang Guang returned from the Western Regions, he ordered merchants from the Western Regions and other countries to come directly to Luoyang to trade, and for a time people with yellow hair, blue eyes, white skin and black skin filled Luoyang, and Luoyang showed an unprecedented prosperity.

In the first month of 610, as soon as the Lantern Festival passed, Yang Guang issued an edict to hold a month-long grand welcome ceremony in Luoyang, welcoming envoys and merchants from various countries to Luoyang, and putting silk on all trees to show the strength of the Great Sui State. At the same time, it was ordered that all merchants must dress up and sell goods, and all hotels and inns in Luoyang must entertain merchants from various countries free of charge, and the stores should pay for themselves.

Hearing this order, the owners of the restaurants and inns in Luoyang were dumbfounded, and many shops of the gate valve family found reasons to close their doors.

So Yang Guang ordered that anyone who dared not open the door would be confiscated by the shopkeepers, and other stores must set up a stage to sing a big opera, and 10,000 musicians were summoned all day to play non-stop every day. At this time, the gate valve was dissatisfied with Yang Guang's behavior to the extreme, and the people were dissatisfied.

This is not the end, after the end of the welcome ceremony, Yang Guang issued an even more stunned order, the northwest states should unconditionally aid the countries of the Western Regions, and the countries of the Western Regions should give what they do not have, and some will also give, and all of a sudden the people of the northwest states who are not rich will be exploited to make a living.

In the same year, Yang Guang once again toured the capital of Xingjiang, with more than 2,000 ships, more than 80,000 slender men, and more than 100,000 soldiers and horses.

At the beginning of 611, Yang Guang returned to Luoyang from Jiangdu and mobilized more than one million troops to crusade against Goguryeo, because the Goguryeo king Gao Yuan promised to pay twice the annual tribute for a year and then did not give it, which made Yang Guang how could he bear it. So while mobilizing the army, in order to facilitate the transportation of grain, he ordered people to dig the Yongji Canal, a canal from Luoyang to Zhuozhou, and requisitioned more than one million people.

At the same time, he ordered Shandong to build 300 large ships, Henan to build 50,000 oxen and horses, and 600,000 people to transport grain.

In this way, two-thirds of the world's population is on the construction site, and the fields are barren, and the people of the world are really unbearable.

In the autumn of the same year, the Yellow River flooded, and more than 30 counties in Henan, Anhui, and Shandong were flooded. In October of the same year, the Zhuzhu Mountain collapsed, blocking the course of the Yellow River, and the river flowed backwards, flooding the vast area of the Guanzhong Plain.

Even so, Yang Guang did not think about disaster relief and continued to send troops to conquer Goguryeo.

Shandong Wang Bo's "Song of the Death of the Waves of Liaodong Wave": Zhishilang in front of Changbai Mountain, pure red Luo brocade crotch... For example, if Liaodong died, he was injured by beheading. After that, Wang Bo led the people to rise up and sounded the assembly call of the dead Sui.

Dou Jiande of Hebei, Zhai Rang of Wagang, Wang Bodang of Jiyang and others rose up in response, and for a time the rebel armies in the entire Central China region rose up and broke away from the imperial court.

On the one hand, Yang Guang sent his imperial uncle Yang Lin to lead a large army to suppress the rebels, and on the other hand, he personally led the army to begin the first conquest of Goguryeo in 612.

Because the elite of the Sui army was transferred away by Yang Guang, the official army led by Yang Lin was far weaker than the righteous army, so the control scope of the righteous army became wider and wider, and the uprising team became larger and larger.

In September of the same year, due to Yang Guang's improper command, he withdrew to Luoyang after losing 300,000 troops, and soon after returning to Luoyang, Yang Guang once again ordered the conscription of troops to prepare for the second crusade against Goguryeo.

For a time, the rebel armies from the north and south of the river rose in all directions, Du Yanbing and Wang Run in Liaodong, Li Deyi and Han Jinluo in Shandong, Bai Yu in Lingwu, Du Fuwei in Yuhang and others revolted one after another, plus Dou Jiande and Wagang Zhai Rang in Hebei who had already rebelled, and the Great Sui rivers and mountains bloomed everywhere and became a pot of porridge. The eighteenth road against the king and the sixty-fourth road smoke and dust have since become the protagonists of history.

Prime Minister Su Wei and others persuaded Yang Guang that he must first settle down inside, after degrading a few ministers, no one dared to write and say things, and Xiao Yu was demoted out of Beijing at the same time, and went to Chongzhou to be a Taishou, and wrote a letter to Gao Buer before leaving, and Gao Buer asked him to train, stick to it, and wait for change.

In order to quell the rebellion, Yang Guang ordered the local Taishou, Li Yuan, Yang Xuangan, Wang Shichong, Yu Wenhua and so on to train troops on the spot to quell the rebellion, and Li Shimin was also released back to Taiyuan to assist Li Yuan in quelling the rebellion in Longxi.

Gao Buer, who was in Hangzhou, also received an order from Yang Guang, ordering him to lead troops to fight against Buchen, and Gao Buer transferred 5,000 soldiers and horses from the northwest, plus 7,800 people he trained in Hangzhou, to form a team of 13,000 people and began to participate in the counterinsurgency. At the same time, he secretly transferred Zhuangzi's personnel to the islands he occupied overseas to avoid the scourge of war, but the three ladies stayed.
