In July of the thirteenth year of the Great Cause (617), the Sui court sent Xue Shixiong, the general of the Right Yiwei, to lead 30,000 horses to attack Dou Jiande, and the scene was very magnificent.

But the mysterious strange man of the weather always likes to amuse people: Xue Shixiong Xingshi mobilized more than 30,000 people to work hard to produce certificates, and when he was going to meet with Dou Jiandede's troops in the south of Hejian City, it was estimated that the weather stranger was in a bad mood at this time, sighed and spit out a big thick fog, so that the eyes of both sides were wide open, and they couldn't distinguish each other clearly, and there were too many of their own people, and their own people mistook their own people for enemies, and they ran away, and in the process of escaping, they trampled on each other, and more than 10,000 people died, and the dead were really worthless.

Xue Shixiong fled with a few hundred people, regardless of whether the rest of the people were dead or alive, the leader ran away, and the fog was so big, the rest of the people were easily defeated by Dou Jiande, and they got a lot of baggage equipment and military horses.

Xue Shixiong was defeated by the weather and Dou Jiande, and even more so by himself, and before a battle really started, he ran away, allowing the enemy to take advantage of it effortlessly.

Then, with the joy of victory, Dou Jiande attacked Hejian County, but Hejian County was a hard bone, and he didn't gnaw it down for a long time, but God helped him, the food in the city was finished, and after receiving the news that Emperor Yang of Sui was destroyed by Yu Wenhua, Wang Cong of Hejian County surrendered to Dou Jiande out of various considerations. It's really icing on the cake, Dou Jiande has won many counties one after another, and got a super delicious cake - Wei Dao'er, the leader of the Hebei Peasant Rebel Army, this Wei Dao'er is very weighty, with 100,000 horses, entrenched in Shenze County, but in the end he was beaten down by Dou Jiande, occupied his men and horses, and annexed his territory. As for his woman, it is expected that Dou Jiande is not contaminated, because he is very afraid of his wife Cao. Dou Jiande I is a hero, but a veritable wife is strict and rakes his ears.

In the first year of Tang Gaozong Wude (618), Dou Jiande, like many rebels in history, had a little army and occupied a little land, and he wanted to be king and hegemon. Dou Jiande is this person, who is called the king in Leshou, the country is called Xia, and the year is Wufeng.

Dou Jiande hanged Yu Wenhua in order to get the heirloom jade seal of the Sui family from him, and provide a basis for him to compete in the Central Plains and dominate the world. He was extremely dissatisfied with the Sui family in his heart, and with the ambition to occupy the Sui family, he had to find a high-sounding reason, so he said to his internal history servant Kong Deshao: "As a subject of the Sui Dynasty, the two generations of monarchs of the Sui Dynasty are my benefactors. Right now, Yu Wenhua and the strangulation of the second-generation monarch Emperor Sui Yang are really rebellious, and they are considered the enemies of our people, and we should go to crusade against him. ”

Kong Deshao said: "The Sui room has no master, and the heroes and heroes of the world are competing for each other, and they all want to ascend to the throne and look down on the world." The king raised troops as ordinary people, and the officials of the counties and counties of the Sui Dynasty rushed to join the king, all because the king obeyed the will of the people and used etiquette and righteousness to stabilize the world. First of all, he is related to the court by marriage, and secondly, the father and son and brother are in incomparable official positions in the Sui Dynasty, but they have done the betrayal of killing the monarch and rebellious, usurping the throne of the Sui Dynasty, with his ability and virtue, he cannot let the people of the world live a good life, and he is the public enemy of the world. For such a bad person, a leader of the righteous army like the king should take the initiative to stand up and a person like Chen Fa. ”
