Huo Qubing
Xiongnu is far away from the Central Plains, and every expedition has to go through a long journey to reach the battlefield. The soldiers and horses have not moved their food and grass first, and the long journey is bound to bring enough food and grass to ensure logistics problems. Huo Qubing, as a famous fighter against Xiongnu, personally gave his army a lot of resources every time he went out. He once sent the meat of 10 wagons to the front with the troops for the soldiers to eat.
However, Huo Qubing didn't touch the 10 car meat. He pulled the meat of 10 cart from beginning to end, and it didn't move. Even later, it rotted away and was not eaten by soldiers. Many people in the army questioned this and even were very dissatisfied. They think that General Huo Qubing is in a high position and doesn't understand the feelings of ordinary soldiers. In fact, Huo Qubing's background is not very good. His mother is just a handmaid, and his father is a small official. He didn't reach the summit until after the exposure, so he certainly didn't know how to save resources.
Many historical experts have analyzed that the reason why Huo Qubing didn't move the wagon of 10 was to keep the distance between him and his generals and soldiers. If soldiers are too good to their opponents in the frontier, it is easy to rely on the Lord, follow the Lord instead of the emperor, and even fear the Lord more than the emperor, forming a situation of high work and low work. Many generals in history were killed because of their high political achievements. Huo Qubing knew this, so he kept his hand.
