Laozi's name is really related to his ears. He has two ways of calling this name: First, it is said that his ears are very big, so he is called Li Er; Second, because of the respect of the world.
First, if we look closely at the statues or portraits of Laozi, we will find that his ears are very different. It is because of his ears that he got the name Li Er. Legend has it that after Laozi was born, his parents were scared when they saw Laozi. The couple found that the child's ears were different from those of normal people. The child's ears were too big! So as soon as the couple discussed it, they gave Lao Zi this name.
The names given to children by the ancients were not all elegant, but most of them were casual. For example, Liu Che was called Kuier to support his family, and Jin Chenggong had a mole on his ass called black buttock, and there are many such examples.
second, the second way of saying it is: actually, Lao Tzu's ears are not big, and he is called this name because the world respects and respects him. Why? Because Laozi is a saint, and the traditional Chinese characters of the holy word have an ear word and a mouth word. This shows that being a saint has something to do with the ears and the mouth. The ears should listen to the opinions of all parties and the mouth should spread their thoughts, and then it will become a realm of omniscient and omniscient.
Because Lao Zi's surname is Li, he is called Li Er by the world. When I get here, I'm afraid some people will think, why not call me Li Kou? After all, there is still a mouth in the traditional Chinese characters of St. That's because listeners have been more popular than confidants since ancient times.
These are the two reasons why I named Li Er.
