Foot, is an honorific, honorific title for the other party, can be translated as "you". Literally, it's hard to think of this, because it contains a historical allusion. During the Southern and Northern Dynasties, a literati named Liu Jingshu wrote a book called "Alien Garden". In this book, the origin of "foot" is introduced.
Uncle Liu Jingshu was an ordinary man who had served as Lang Zhongling. He later rebelled against his superiors and was removed from his official position. Uncle Liu Jing was not discouraged, focused on writing books, and left a collection of Zhiwei novels "Alien Garden" to be handed down. The content of the book "Alien Garden" is mainly anecdotes, which is not valued by readers, so not many people know about this book.
According to the records of the "Alien Garden", during the Spring and Autumn Period, the princes of the Jin Dynasty fled to avoid disasters. On his way to escape, he befriended the Magi, was humble and studious, and gathered around him a group of sages who supported him. After 19 years of exile, Zhong'er never forgot to regain power in the Jin Dynasty.
Qin Mugong heard the story of Zhong'er and helped him kill the Duke of Jin, and Zhong'er finally became the monarch of the Jin State, known in history as "Duke Wen of Jin". After the restoration of the country, the rewards and punishments were clear, the trade was wide and the peasants were generous, and the Jin state soon became the hegemon of the various princely states.
According to the size of the merit, the heavy ear rewarded the courtiers who followed him on the road of exile. At this time, he was reminded that there was another famous scholar named Mezi Tui who had not been rewarded. If you don't reward him, I'm afraid it will damage your good reputation. The heavy ear was confused at once, and there was no meson pushing around him. It turned out that The meson pushed this person not to seek fame and fortune, and when he saw that The Heavy Ear Gong had become famous, he ran to Mianshan mountain and lived in seclusion. After being reminded, the heavy ear only remembered the meson push.
Heavy ears must reward the meson push, and the meson pushes to hide from people. Heavy ear several times three times can not find anyone, and then angry. No one expected that Zhong'er actually made a faint move, and he sent people to burn Mianshan to force Jiezi to push out the mountain to accept the reward. The fire burned the mountain so hard that it became a ruin, and people found that The meson was holding a tree and burning it to death.
Only then did he feel regret that he could not take the life of the Magi without a reward! In order to block the mouths of the people, the heavy ears pretended to be hurt. Heavy ears caressed the charred dead wood, weeping and weeping in mourning the meson push. After crying, the heavy ear ordered the man to make a pair of wooden shoes out of the leftover wood.
Later, people often saw heavy ears holding a pair of wooden shoes, and the mouth chanted "sad feet". Over time, there is the title of "foot".
The story of "Yiyuan" may not be credible, but judging from the works passed down from generation to generation, as early as the Western Han Dynasty, "foot" had the meaning of "you". For example, Sima Qian wrote in the "Book of Baoren An" that "Shaoqing's foot" is this usage. It can be seen from this that at least in the period of Emperor Wu of the Han Dynasty, the word "foot" was already a common word.
The Warring States Policy compiled by Liu Xiang of the Western Han Dynasty also has the word "foot" in it, which also means "you". With these examples, it is further proved that the word foot has been used as an honorific title in the Western Han Or Pre-Qin period.
