If you have seen "Sui and Tang Yanyi", you will know that there is a big villain named Su Dingfang, who killed The Duke Luo Yi of Yanshan when he attacked Yanshan after defecting to Dou Jiande, the King of Xia, and later fought against the Tang Army, and after the defeat, he defected to Dou Jiande's department to kill Liu Heimin, and outside the Bauhinia Pass, he played a conspiracy and trick to kill the most popular character Luo Cheng, which made countless people hate their teeth, but everyone was a little wronged Su Dingfang's classmates, although Old Su was blackened by "Sui Tang Yanyi", although Old Su was blacked by "Sui Tang Yanyi", However, in fact, he was a great general who could be on a par with Qin Shubao, and once led his subordinates to sweep away the three surrounding countries. It has made great contributions to the expansion of the Tang Dynasty.
Su Dingfang was a native of Shanxi, and in the last years of the Sui Dynasty, Su Dingfang's father, Su Yong, led thousands of township soldiers to fight against the thieves, and at this time, the 15-year-old Su Dingfang had already begun to kill the four sides. After Su Yong's death, Su Dingfang inherited his troops, and at that time, the Sui Dynasty was tyrannical, and anti-Sui forces swarmed everywhere.
Su Dingfang also realized that he was following the sui dynasty old Yang family, sooner or later he was going to die, he immediately defected to the then leader of the Hebei rebel army Dou Jiande, Su Dingfang thought to himself, this person is so powerful, the world should be his in the future, I will follow him!
Unexpectedly, Dou Jiande was also a bluff guy, so much territory, so large army, the result was vulnerable in front of the Tang people, after Dou Jiande's death, Su Dingfang defected to his old general Liu Heimin, the king of Handong, and continued to fight with the Tang Dynasty, Su Dingfang's ability was very strong, and he laid down a lot of Tang Dynasty cities for Liu Heimin, and many lands in the Tang Dynasty fell.
The news reached Chang'an, the then emperor Li Yuan was very panicked, his emperor position was not hot, hurriedly sent his son Li Shimin to encircle and suppress, WuDe six years (623), Liu Heimin was defeated and killed, Su Dingfang was also a disciplined person, returned to his hometown, no longer serving the Tang Dynasty.
But his ability gave Li Shimin a very big impression, after Li Shimin ascended to the throne, the border has been harassed by the Eastern Turks, and when there is nothing to do, he will come to plunder the resources of the Tang Dynasty border, Li Shimin is not as tolerant as his father, and ordered Li Jing to be the main general and go on a crusade against the Turks. However, the veteran of the conquest at that time had already died of illness, and no one could give Li Jing a hand.
At this time, Li Shimin suddenly thought of Su Dingfang, who had discipline, and immediately ordered him to go out to the Turks as a deputy general, and under the eaves, Su Dingfang did not dare to disobey the orders of the Heavenly Son, and then led the army with Li Jing, in this battle, the Tang army killed the Eastern Turks, and Su Dingfang's command was inseparable, and after returning, he was soon named the General of the Marquis of Zuowu.
Although Su Dingfang is very talented, but Li Shimin always has something in mind for him, you are so powerful, in the past you were a fresh force against the Tang Dynasty, the ghost knows what you will think in the future, so after this battle, Li Shimin ruled for more than twenty years, Su Dingfang has not been promoted, and Li Shimin has only used it once.
After Li Shimin's death, to the stage of Tang Gaozong, at this time there were even fewer experienced veterans left, at this time the border area was not stable, there were Western Turks in the west, Goguryeo in the east, Tang Gaozong thought of Su Dingfang with an idle expression, then it was decided that it was you! Send him to battle.
In the subsequent wars, Su Dingfang conquered the Western Turks, Yi Baekje, and attacked Goguryeo, "destroying the three kingdoms before and after, and capturing their masters", and unprecedentedly expanded the territory of the Tang Dynasty to the west to the Aral Sea of Central Asia, and the border reached Persia and extended east to the south of the Korean Peninsula. Helped Emperor Gaozong of Tang become the "Lord of All Nations". If Li Shimin had used this person earlier, perhaps the Tang Dynasty would have become more powerful.
