The Daming Palace of the Tang Dynasty is the largest and most luxurious and magnificent palace complex among the three palace complexes in Chang'an City. It is perched on the Dragon's Head Plain in the Forbidden Garden in the north of the city. From it, you can see thousands of peaks in the southern part of the city as clearly as the palm of your hand, and you can overlook the streets and streets in the capital city as if you were within the threshold. So, why was it built on the original head of a tall dragon, and why was it named after "Daming" Eryu? When Li Yuan and Li Shimin first established the Tang Dynasty, there was only Taiji Palace in Chang'an City. And this Tai Chi Palace was not newly built in the Tang Dynasty, but old in the Sui Dynasty. After Li Yuan became the founding emperor of the Tang Dynasty, he wanted to build a new luxurious palace to enjoy the happiness of the world. However, due to the advice of Li Shimin and other wise ministers, he had to give up. Later, King Li Shimin of Qin became emperor as Taizong of Tang Dynasty. He respected Li Yuan as the Supreme Emperor and spent his remaining years in the palace. This Li Yuan is a mediocre and greedy person. He was not satisfied with having fun in the Tai Chi Palace. He felt that the Tai Chi Palace was low-lying, humid in autumn and sultry in the summer. He also felt that the rooms in the Tai Chi Palace were small and old, so he was unhappy all day long. I deeply regret that when I was the emperor, I did not take the initiative to build one or two magnificent palaces. Seeing that his father was unhappy, Taizong asked his father about his discomfort and requests during the morning and evening, but Li Yuan remained silent. Tang Taizong, who had many things to do, was too busy dealing with state affairs, so he did not delve into the matter further. Soon, Li Yuan finally became depressed and became ill. Taizong became anxious, but when he asked his father, Li Yuan still didn't speak. He had to ask his mother, Empress Dowager Dou. Empress Dowager Dou was a sensible person. Although she told Li Yuan's "heart disease", But he also advised his son not to use the funds of the treasury to build a new palace, and let his son deal with the important affairs of the government wholeheartedly, leaving the matters of advising and regulating Li Yuan to himself. But this time Taizong did not dare to take it lightly. He issued an edict to use his private savings to build a temporary summer palace for his father on the Gaofu at the beginning of Longshou in the north of the city. He named it "Yong'an Palace", hoping that after his father lived in it, The dragon body can recover and enjoy eternal peace and happiness. Unexpectedly, Li Yuan died of illness shortly after the groundbreaking. Taizong thought: Since his father could not live in it, let him build it for his mother to live in. Therefore, the construction of Yong'an Palace continued. On this day, the craftsmen were digging the foundation of the main hall, and suddenly a dazzling golden light emitted from the ground. The craftsmen did not dare to dig any more, so they went to report to Taizong. Taizong personally visited the construction site and ordered the craftsmen to continue digging. As they dug and dug, they suddenly saw something radiant and dazzling. It turned out to be a huge ancient bronze mirror. This mirror was five feet nine feet high. inch, four feet wide, the face is like the sun, shining with golden light, the back is like the moon, the clear brilliance can be seen, the surrounding patterns are simple, and dust does not stick to it. After Taizong looked at it, he couldn't recognize the treasure from which generation it belonged, so he humbly asked the accompanying officials such as Fang Xuanling and Wei Zheng for advice. Wei Zheng motioned to Fang Xuanling to speak first, and Fang Xuanling asked Wei Zheng to speak first. Taizong saw his two ministers playing riddles, so he ordered the general: "Wei Aiqing, please speak first, and Fang Aiqing will add later, how about that?" Wei Zheng stroked his beard and spoke without hesitation. It turns out that this precious mirror is the famous Qin Mirror, which has been kept in the Xianyang Palace of Qin Shihuang. There is a strange thing about it. If you look into the mirror from the opposite side, the person's reflection will be reflected inside. If you put your hand on your chest, you can see the internal organs in the body. The image is very clear and every fiber is visible. More importantly, it can illuminate the loyalties and traitors of the ministers and the rise and fall of the country's destiny... This is indeed a national treasure that can distinguish authenticity from falsehoods, reveal loyalty and traitors, diagnose national diseases, and protect the country. However, Qin Shihuang only used it to take care of the maids in the palace. Anyone who was "daring" would be beheaded as someone with different intentions. Hu Hai, the second emperor of the Qin Dynasty, went even further and killed many people, but he left behind traitorous ministers such as Zhao Gao who regarded deer as horses and monopolized power to harm the country. Qiang Qin, who became famous for a while and feared the Xiongnu, died in an instant. When Liu Bang, the great ancestor of the Han Dynasty, first occupied Xianyang, the capital of Qin, Xiao He persuaded him to seal off all the palaces including Xianyang Palace and Epang Palace. He did not want any gold, silver, treasures, children, jade, silk, bells, tripods, dogs or horses. He only took away all the books, scrolls, books and scrolls in the Qin Palace. Then there is the national treasure - Qin Mirror.
Because of this precious mirror, Han Zuo was able to last for hundreds of years! At the end of the Han Dynasty, when heroes were vying for hegemony, Qin Jing was nowhere to be found. Who knew that hundreds of years later, Qin Jing would be born again on Longshou Plain! Having said this, Wei Zheng bowed deeply to Taizong and congratulated him: "The birth of Qin Jing today heralds the eternal greenness of the Tang Dynasty. This is due to your majesty's great blessings. I congratulate you!" After hearing this, Taizong pushed away the two men. A chamberlain carried the Qin Mirror and said, "What do I need this mirror for? I have already obtained a mirror that is thousands of times better than the Qin Mirror!" Hearing this, Wei Zheng blushed, and the mature Fang Xuanling But he asked in confusion: "Where is Your Majesty's bright mirror? Can I show it to you?" Taizong put his hand on Wei Zheng's shoulder and said: "Wei Aiqing is my bright mirror! Fang Aiqing, don't you think so?" Ha!" Fang Xuanling clapped his hands and said with a smile: "Your Majesty is right, I congratulate you! Hahaha!" Wei Zheng's face became even redder, he leaned over and said thank you, "How dare you, Wei Chen? Qin mirror is superior! Your Majesty has given you the award..." Taizong said solemnly: "I use copper as a mirror to dress my clothes, use ancient times as a mirror to know the ups and downs, and use people as a mirror to know the gains and losses. Remonstrate with me so that I can understand gains and losses. Isn’t it a high-hanging mirror for me? In order to remember the meeting of the monarchs and ministers today, I specially changed this Yong’an Palace to Daming Palace!”
