The Guanzhong area is surrounded by mountains and rivers, fertile fields, fertile land, abundant products, and developed economy. There are Xiaoguan in the north, Sanguan in the southwest, Wuguan in the southeast, and Hangu Pass in the east, which is known as "the land of four stops, the golden city of thousands of miles, and the country of abundance".

Chang'an, the political, economic, and cultural center of Guanzhong, is like a shining pearl inlaid in the rich land of Guanzhong. Adhering to the "not magnificent and insignificant" and the construction of Chang'an City, the east and west are about 9,700 meters long, and the north and south are about 8,600 meters long, majestic and magnificent.

In Chang'an City, the main street and Zhufang Lane, large and small shops, even the door, no empty house, the shops are numerous, lively and extraordinary, people come and go on the street, shoulder to shoulder, neck back to each other, busy traffic.

The grandeur of Chang'an City and the liveliness in Chang'an City surprised Li Xuan, who came as a later generation, and at the same time, he felt happy.

The Tang Imperial Palace is located in the middle of Chang'an City, the scale is grand, brilliant and magnificent, majestic and magnificent, it is the political center of the Tang Empire, and it is also the largest palace complex in ancient China and even in the world, covering an area of 350 hectares, which is equivalent to 4 times that of the Forbidden City in Beijing in later generations, with more than 50 palaces and attics, and is the ruling center of the entire Tang Empire.

When I approached the palace, I saw the crown prince Jiancheng and the king of Qin, Li Shimin, leading hundreds of civil and military officials to greet them outside the palace gate. Li Xuan and his entourage couldn't help but speed up their pace, and walked to the front of the crown prince Jiancheng and the king of Qin, Li Shimin, who had just stood still and had not yet spoken. I heard a sharp voice shouting, "Your Majesty has arrived." ”

Li Xuan and his entourage bowed together with the crown prince Jiancheng and the king of Qin, Li Shimin, and said, "Welcome Your Majesty." ”

Through the peripheral vision of his eyes, Li Xuan saw a burly middle-aged man with white hair and yellow robe walking towards him.

Li Yuan walked up to Li Xuan and said excitedly: "You are Li Xuan, the son of Xiaoji?" ”

Li Xuan replied respectfully, "Yes." Then under the gaze of everyone, he slowly knelt down and bowed to Li Yuan.

Li Xuan knelt down and saluted, which caused heated discussions among hundreds of officials.

"Bow down? Apprenticeship? ”

"How can you make such a big gift? Isn't it an uncle-nephew relationship? ”

"Nervous, wrong salute? Definitely. ”

"Lee Hyo-gi's old face made his son lose his name. It's a shame and a big shame, in front of the prince, the king of Qin, and the hundred officials, he won't even be able to salute. Li Xuanhu's father and son, but Erer. ”

In the midst of everyone's discussions, Li Xuan calmly finished the apprenticeship and slowly stood up.

Li Yuan didn't seem to hear everyone's discussion, but stared at Li Xuan, and said excitedly: "Like, really like." ”

Li Xuan bowed to Li Yuan again under the gaze of everyone.

"Salute again, what kind of trouble are you going to make?"

"Bowing? That's right, this is what nephews should do to their uncles, and courtiers should do to the emperor. ”

"That's when I realized that it was too late. Li Xiaoji's face made him throw him to his grandmother's house. ”

The officials of the wealthy clan in Shandong and the southern clan have always held the orthodoxy of the Han nationality and looked down on the Guanlong nobles and the Li royal family, so they sneered: "The Guanlong nobles, Hu Rong also; Longyou Li, Hu Rong also; The son of Li Xiaoji, the first smart man of the Longyou Li family, can't get rid of the habits of the Hu people, I don't know the orthodox etiquette of my Yangyang Huaxia, how dare the Longyou Li family say that it is the Hanfei general Li Guanghou? Han orthodoxy? ”

Zhao Meng, Sun Simiao, Xiong Kuohai, and Pei Xingjian were also surprised, they couldn't understand: how could Li Xuan, who is usually very shrewd, make such a lowest-level mistake?

Li Shimin, the king of Qin, looked at Li Xuan, who was saluting in a proper manner, and shook his head again and again.

The crown prince sneered: "What is it? It is even worthy of such a greeting from Lone and his father? Waste one? ”

At this time, Emperor Li Yuan realized that Li Xuan had saluted him twice, and the first time was a great bow to his teacher, he wanted to ask, but he was afraid of embarrassing Li Xuan again, so he had the heart to avoid it.

Li Xuan guessed Li Yuan's thoughts, and said, "Your Majesty personally greeted Li Xuan, which flattered Li Xuan. Li Xuan saluted His Majesty twice, but there was a reason for the incident: one was for public and the other was private. ”

As soon as Li Xuan's words fell, the ministers began to discuss again: "Since it is the first time to bow to the public, how can you bow to the teacher?" Your Majesty is not a Taoist priest? ”

"Although Your Majesty is not a Taoist, Your Majesty has a great relationship with my Taoist. His Majesty is the Son of Heaven, and he is also the head of the Li family in Longyou. And Longyou Li is the descendant of my Taoist Taiqing sage - Lao Tzu. According to the seniority, Your Majesty and my master Qingyun Zhenren are the same generation, I worship the teacher, what's wrong? Li Xuan said categorically.

Li Xuan's words were like a boulder falling into the sea, and a stone stirred up a thousand waves, which immediately shocked everyone.

"Longyou Li, the Taiqing sage - the descendant of Lao Tzu? How so? ”

Everyone present knew that the Taiqing sage Lao Tzu was a special identity, he was not only the ancestor of the entire Taoism, but also had a wide range of believers in the whole world, and he was also the teacher of the Confucian sage Confucius, who had asked Lao Tzu about etiquette and sought knowledge. And all the scholars in the world are protégés of the Confucian sage, and Confucius Thought is also the orthodox thought of the entire Han nationality.

Shangshu left servant shot, Guan Long aristocratic chief Pei Lian's brain is running fast, if Longyou Li is the descendant of the Taiqing sage Lao Tzu, Lao Tzu is a native of Chu State, is Han orthodoxy, there is no doubt about this, then Longyou Li must also be Han orthodoxy. In this way, the Shandong Hao clan and the southern scholar clan, who have always looked down on the Li family, can no longer target the Longyou Li family, saying that the Longyou Li family is of Hu blood, which is also conducive to the support of the scholars in Shandong and the south, and His Majesty, as the descendant of the Taoist patriarch, will inevitably be supported by the vast number of Taoist believers in the world, after all, Taoism as a local religion has been developed for hundreds of years, and almost every village has a Taoist Taoist temple, which is very important for stabilizing the rule of the Tang Dynasty. Thinking of this, Pei Lin decided to use the agitation method to provoke Li Xuan, so he feigned anger and said: "Huangkou Ruzi, in front of His Majesty and hundreds of civil and military officials, how can you be honest and talk nonsense?" ”

Everyone immediately came to their senses, Li Xuan was just a teenager, and the Li family of Longyou was the descendant of the Taiqing sage, and this matter was said by Li Xuan, maybe it could not be true.
