It should have a bright future, but it's really embarrassing to end up like this. Some people may think that An Lushan rebelled because all his subordinates were clan troops, and they were not loyal enough to the Tang court. But in fact, the rebel groups in the Anshi Rebellion did consist of dozens of ethnic groups, but the Han nationality was not a minority, even the main force of rebellion.
In fact, Xue Gang is not a man of strategy, but he chose to join the rebels because he just wanted to show his talent. When he was defeated, he surrendered without hesitation. So to some extent, Xue Song's behavior is blind obedience without thinking, which is related to his dislike of reading. From this perspective, Xue Gang rebelled against the Tang Dynasty only because young people chose to follow blindly without careful consideration.
Later, the rebels lost their momentum, and Xue Gang had to surrender to the court for the sake of the family's life and death. I should say he's ready to confess. Fortunately, the policy of the imperial court was very tolerant, and Xue Gang gained a high position without struggle. Although Xue Gang had no education, he was also very grateful to the imperial court. From then on, he was loyal to his duties and dared not have second thoughts. Of course, this is not to say that Xue Gang made great contributions, but that the Tang Dynasty was in decline and had to win the hearts and minds of the people with unexpected officials.
