The origin of the mirror is Mu Mu, also known as the ugly girl. 5,000 years ago, in order to stop the tribe's "robbing marriages", the Yellow Emperor specially selected an ugly girl (titled Ai Mu) who was virtuous, gentle, and ugly in appearance as his fourth wife. The Yellow Emperor also said: "Those who value beauty but not virtue are not truly beautiful. Those who value virtue but not color are truly virtuous." 5,000 years ago, the Yellow Emperor fought against Chiyou and descended on Shen Nong, quelling the war and unifying the three major tribes. After the barbaric era, mankind has just begun to enter civilized society. Making clothes, crowns, boats and cars, and dressing up have become indispensable things in everyone's daily life. At that time, in order to tidy up their unkempt appearance, the ancestors often faced a basin of water, or stood by a calm river or waterside to tidy up. Therefore, ancient books record that this kind of "looking in the mirror" is called "viewing water". So, what does this have to do with Aumu? According to legend, Aumu discovered and made the first mirror used by humans. At that time, people in Huangdi's palace often stood by the water to reflect their faces and dress up. My mother-in-law felt that she was ugly, so she seldom went to the waterside to dress herself up, and she did not show her face casually during festivals. He only knew how to work beside Huangdi all day long. One time, Mrs. Tongyu asked her mother to go up the mountain to dig stone slabs with her. Without saying anything, her mother followed Tongyu and asked her mother to go up the mountain with her. My mother is very strong and can dig stone slabs faster than other women. In less than half a day, more than 20 pieces were dug. At this time, the sun was at noon and the sun was shining all over the earth. Auntie's mother suddenly found a shiny stone piece in the pile of stones, which was very dazzling when the sun shone on it. My mother bent down and dug it out from the ground gently with her hands. When she took a look at it in her hand, she couldn't help but be shocked. What kind of monster is this? Its ugly face is reflected on this piece of stone. Even she herself found it strange! She secretly hid the stone piece on her body and did not tell anyone about it when she returned to the Yellow Emperor's Palace. When there was no one around, she took out the stone piece again and found that the surface of the stone piece was uneven. The face reflected in it looked strange. Mom went to the factory where stone knives and axes were made, found a grindstone, pressed the stone on it and rubbed it repeatedly. In a short time, the surface of the stone was completely smooth. She took a photo and it was much clearer than before. But his face is still so ugly. She rubbed it for a while, picked it up and took another photo. She was still ugly. Auntie's mother sighed to herself: "It seems that the ugly face cannot be blamed on the stone (mirror)." From then on, Auntie's mother never went to the river or waterside to dress up again. Get up every morning, look at the stone tablets, tidy up and dress yourself up, and then hide them quietly after use. As time passed, my mother became careless. One day, Auntie's mother helped Tongyu cook meat on a stone slab. Due to the excessive firepower, the stone slab was burned and a piece of gravel flew up, breaking Auntie's face and causing bleeding. My mother hurried back, took out the stone tablets, and applied medicine on her face. Unexpectedly, Huang Di came back at an unknown time, and walked quietly behind his mother, and found that his mother was holding something to shine on him with one hand, and applying medicine to his face with the other hand. Huang Di walked behind Aunt Mu and put his head close to Aunt's shoulder. Just when he was about to take a closer look, Aunt Mu exclaimed! She found the face of the Yellow Emperor appeared on the stone. She turned around and saw that Huang Di was standing behind her. Huang Di asked his mother: "What are you holding in your hand?" Upon hearing Huang Di's question, the honest and loyal mother knew that she could not deceive Huang Di about this matter, so she knelt down in front of Huang Di with a bang. Aimee's mother told the Yellow Emperor everything she had found about the illuminated stone, and begged the Yellow Emperor to forgive her. After Huang Di heard this, he laughed loudly, picked up his mother with both hands and said, "This is a great discovery for you. Not only are you right, you have also made a great contribution!" After Huang Di said this, he immediately called Lei Zu, Fang Lei and Tong. Mr. Yu, take out the piece of stone that can reflect people's faces, and ask her three wives to see it. Lei Zu smiled and said: "Huang Emperor, no wonder I haven't seen my mother go to the water to dress up for a long time. It turns out that she has this treasure that shines on people." Tongyu then said: "Huang Emperor, this discovery should be recorded to my mother and sister. One meritorious service!" Huangdi said excitedly: "Of course one meritorious service must be recorded!" The use of mirrors by humans began in the history of the Chinese nation. Therefore, stone mirrors appeared first. With the development of smelting technology, humans invented iron mirrors and bronze mirrors. 4,000 years ago, ancient bronze mirrors appeared in Egypt. Later, bronze mirrors were also unearthed in our country. After the Qin and Han Dynasties, my country's bronze mirror manufacturing level has become famous both at home and abroad. Bronze mirrors are not only tools for dressing and plastic surgery, but also beautiful handicrafts. Nowadays, we use a lot of glass mirrors.
