How did the name "Ma Xu" come from? Who was the first "Ma Xu" in the history of China?

Ma Xu was the title of son-in-law of the ancient royal family in China. In China's 2,000-year feudal history, Ma Xu has always maintained a radiant landscape image, and he is the groom's official admired by generations. Most of the images we see now are because of their fame, their marriage to the princess, and their status suddenly jumped. However, do you know how the name "Ma Xu" came from? Who was the first "Ma Xu" in the history of China?

In fact, at the beginning, the name Xu had nothing to do with the princess, just a position, but this position was very low. Because throughout history, we all know that most emperors go out by car, and for safety reasons, every time they go out, there will be several identical cars, only one of which is the main car and the others are auxiliary cars, in order to confuse those with ulterior motives and protect their own safety.

In addition to the emperor, there will be several body double sitting in different carriages to disperse the forces of assassins, thus greatly reducing the chance of being assassinated. And these drivers who drive vice cars are called vice horses. Legend has it that a deputy horse saved Liu Bang's life. Later, Liu Bang thought the name "Deputy Horse" was unsightly, so he changed it to Ma Xu, and the name "Ma Xu" came from it, which has continued to this day.

During the period of Emperor Wu of the Han Dynasty, Emperor Wu of the Han Dynasty set up the position of Governor Ma, who was mainly in charge of auxiliary vehicles. At that time, she had just ascended the position of Xu, and married Princess Jinxiang. In other dynasties, the emperor's son-in-law became Xu, so over time, people called Xu and the emperor's son-in-law, that is, the princess's husband was later called Xu. In other words, it is the first Xu in history.
