Why did Li Guang, who was "Feng Tang yi old, Li Guang difficult to seal", failed to be crowned marquis?

Recently, I was reading a cross-over novel "The Great Han Arrow God", the protagonist traveled back to the western Han Wudi period, with a good archery to fight the Xiongnu, Pingnanyue, made great military achievements, and was awarded the title of Marquis of Ten Thousand Households. And Li Guang was also favored by him, one door and three marquises, and finally achieved the high position of Imperial Master. Of course, this did not happen in real history, so why did Li Guang, who was called "Flying General" by the Xiongnu, not be crowned marquis in the end?

1. The political consciousness is not high, and accidentally hitched a ride on the broken ship of the empress dowager and the king of Liang. He felt that he had gained the trust of King Liang, but Emperor Wen had no intention of passing on his younger brother King Liang, and was bent on passing it on to his son Emperor Jing. The so-called one-day infidelity, a hundred days do not use. From this point on, his path to the throne became extremely difficult.

2. Lack of broad-mindedness. Li Guang's sense of revenge was extremely strong, and he once killed Lieutenant Baling because of a small matter, causing a very bad impact. When the meritorious and rewarded, the ministers of the DPRK did not dare to speak for him, and the road to the title of marquis was indefinitely shelved.

3. Although the hard work is high, but do not pay attention to theoretical study, suitable for being a general but not handsome. He led his troops to fight more casually and simply. Troops marched arbitrarily, and the marching system was not strict enough. As an example, Li Guang's ability is beyond doubt, but he has never been a management talent.

From the perspective of the modern workplace, Li Guang is the epitome of countless conscientious old scalpers in the company. They are hard-working and diligent, and they complete the tasks undertaken by their superiors without compromise, but they do not pay attention to the cultivation of personal connections, and their theoretical reserves are insufficient, and when it comes to promotion, they will not have the opportunity. People can only sigh that "Feng Tang is easy to old and Li Guang is difficult to seal."
