Chang'an, the ancient name of Xi'an, is the first capital city called "Beijing" in history, and it is also the first real city in history. King Wen of Zhou set the capital here, built Fengjing, after King Wu ascended the throne, he built Ho Jing, collectively called Feng Ho, Xi'an is referred to as "Ho" from here. Han Gaozu five years in Chang'an County, on the south bank of the Wei River, the north side of the Afang Palace, the Qin Xingle Palace on the basis of the construction of Changle Palace, Gaozu seven years (200 years ago) to build Weiyang Palace, in the same year the national capital moved here from Liyang, because it is located in Chang'an Township, so the name Chang'an City, take the meaning of "long-term peace and stability".

Chang'an is the ancient capital of the thirteen dynasties, the capital city with the most dynasties, the longest time and the most influential in Chinese history, the first of the four ancient capitals in China, the birthplace of Chinese civilization, the cradle of the Chinese nation, the outstanding representative of Chinese culture, and the largest city in the world during the Sui and Tang dynasties. Chang'an is the eastern starting point of the Silk Road and the starting point of the Sui-Tang Grand Canal, and is the only Chinese city that has been designated as a world historic city by UNESCO so far, and is known as the world's four ancient civilizations along with Athens, Rome and Cairo. With a history of more than 7,000 years of civilization, more than 3,100 years of city building and more than 1,200 years (not counting the accompanying capital), there have been 13 dynasties including Zhou, Qin, Han, Sui and Tang dynasties built their capitals here, and the permanent population of 1.85 million in the heyday of the Tang Dynasty. As the capital of China and the political, economic and cultural center for more than 1,000 years, it is known as a natural history museum and an internationally famous tourist destination city. The influence of Chang'an culture is extremely far-reaching, because the Zhou, Qin, Han, Sui and Tang dynasties that built the capital of Chang'an were the most powerful and civilized golden ages in ancient China, so after the Tang Dynasty, although Chang'an is no longer the national capital, the word "Chang'an" has become another name for the national capital.

Chang'an in the Sui and Tang dynasties can be said to have developed to its heyday, and has always played the position of the center of the world, attracting a large number of foreign envoys and worshippers.

After Emperor Wen of Sui Emperor Yang Jian usurped the Northern Zhou Dynasty and established the Sui Dynasty, he initially set his capital in Chang'an City of the Han Dynasty. At that time, Chang'an of the Han Dynasty had experienced a long period of war, disrepair, dilapidation, and serious pollution, so Yang resolutely decided to build another new city. In the second year of the emperor's reign, Yang Jian chose a place in the south of Longshou Plateau in the southeast of Chang'an City to build a new capital, and the new capital was named "Daxing City". The area of Daxing City is 84 square kilometers, mainly presided over by Yu Wenkai planning and construction, first built Daxing Palace City, and then built the Imperial City. In the third year of the emperor's reign, the Longshou Canal, the Yong'an Canal and the Qingming Canal were excavated on the west side of the city, and the water was diverted, the water was handed over and the water was lushui, and it was directly connected to the palace city. In the second year, more than 300 miles were dug from the east of Daxing City to Tongguan, which was named Guangtong Canal, and the Wei water was injected into the canal to make the Cao Yun directly connected to the Yellow River. In the eighteenth year of the emperor, Emperor Yang Guang of Sui ascended the throne, in the same year, the Tongji Canal was built, from Daxing to Jiangdu, four years of great cause, and the Yongji Canal was built. In the ninth year of the Great Cause, more than 100,000 people were mobilized to build Guocheng outside Daxing City, and the overall pattern of Daxing City was formed. In the fourteenth year of the great cause, after the death of Yang Guang in Jiangdu, Li Yuan called the emperor, established the Tang Dynasty, changed Daxing to Chang'an, and then further built and improved, Tang Taizong and Tang Xuanzong successively built Daming Palace and Xingqing Palace and other palaces.

Now the fourteenth day of the Great Cause has not been completed, due to Zhang Wei's reasons, Li Yuan has not yet been called the emperor, of course, the name of Chang'an has not been used for the fourteenth year of the Great Cause, as early as when Li Mi ripped off the fig leaf of the Great Sui, Li Yuan had already supported Yang Guang's grandson Yang Yu as the son of Yining, and the year name has naturally been changed to "the first year of Yining", of course, the current Chang'an City is not called Chang'an City, but Daxing City.

When Zhang Wei took Shen Luoyan and Lu Miaozi to set off from Luoyang by boat, he had come to Chang'an, the ancient historical capital, in a few days. There are three city gates on each side of the outer city, the six streets that run through the twelve city gates are the traffic arteries of the whole city, and the Suzaku Street that runs through the north and south is a standard central axis, it connects the Chengtian Gate of the palace city, the Suzaku Gate of the imperial city and the Mingde Gate of the outer city, and divides the Chang'an City into two parts of the east-west symmetry, the east is Wannian County, the west is Chang'an County, and the east and west parts each have a business district, called the East City and the West City. There are 11 main streets in the north and south, and 14 main streets in the east and west, dividing the residential area into 110 squares, which are shaped like a Go board. Sure enough, this guy who built the city has obsessive-compulsive disorder, asymmetrical and uncomfortable dead base! Zhang Wei secretly complained.

By the time Zhang Wei and the others got off the boat, there were already two teams of people waiting on the dock. Seeing that Zhang Wei and the three of them had disembarked, two young talents came out of each of the two teams and hurriedly walked towards Zhang Wei. Looking at the two people who were walking hurriedly, Zhang Wei shook his head, Li Valve has already started the brotherly infighting now?

"Jiancheng has seen my cousin!"

"Shimin has seen Brother Dang!" After the two young men walked over, Zhang Wei saluted first, and then arched his hand.

Yes, these two people are Li Jiancheng, the eldest son of Li Yuan, the owner of Li Valve, and Li Shimin, the second son, how can Li Valve not pay attention to the movements of Li Xiaogong, a disciple of Li Valve? Back then, Li Xiaogong and Li Shimin went to Jiangdu after parting, and it can be said that basically no one is optimistic about Li Xiaogong's behavior, Li Valve has more disciples, and one less Li Xiaogong can be said to have no effect; When Li Xiaogong occupied Jiangdu, Li Valve found that Li Xiaogong was already a good help to Li Valve unconsciously; Immediately after the outbreak of Li Xiaogong to face Ning Daoqi, facing Ning Daoqi, one of the three great masters in the world, and even the entire Buddhism, Li Valve decisively prepared to treat Li Xiaogong as an outcast, in order to protect the Buddhism Sect to continue to support Li Valve; However, after the first battle of Jiangdu, Li Valve was slapped in the face, Li Xiaogong not only slashed Ning Dodge with a sword, but also overpowered Buddhism, and during this period, Li Xiaogong had become a candidate in the eyes of Li Valve; Next, Li Xiaogong attacked successively, occupying the Jiangdu area, and even the first line of Pengcheng, Li Valve's tragic discovery, now Li Xiaogong's territory is even bigger than them, everyone has different thoughts, among which the five flavors in the heart of the valve owner Li Yuan are not enough to say; Next, Li Xiaogong went north, and the battle of Jingnian Zen Temple established the invincible momentum of the world, and the people of Li Valve were shocked that they didn't know what to say, and Luoyang fell into the hands of Li Xiaogong in a few days, not to mention. Now Li Xiaogong seems to have become a big man, and Li Valve is just a force that occupies Chang'an.

Therefore, for the arrival of the big man, how can Li Valve not recognise it? Besides, regardless of the news in the open and in the dark, Li Xiaogong has already expressed no interest in the supreme position at all! But the rest of the people have it! Including the valve owner Li Yuan. For Li Xiaogong, a powerful man, to come to Chang'an, naturally people with ideas must have to get in touch, and welcoming Li Xiaogong has become the top priority, how can the valve owner give this opportunity to others! But the valve owner's own internal disagreement, no way, in desperation, Li Yuan decided to send his two sons to go, but the situation really did not allow it, or Li Yuan himself would have come to meet Li Xiaogong. Who let Li Xiaogong control a large number of troops and financial resources! Why didn't Li Yuan come out? Dear, don't make a fuss! Li Yuan, as the owner of Li Valve, is still Li Xiaogong's uncle, if he runs out to meet Li Xiaogong, he will give others the illusion that Li Yuan is ready to hand over the power of Li Valve, so that Li Yuan still has a chance to ascend to the throne? Of course, even if he sent his two sons out to greet Li Xiaogong, Li Yuan was also very uneasy. There is only one position under the buttocks, and no one does it by themselves, and the problem is that it is even more ugly for people to get it down after doing it for a few days. In his thoughts, in fact, he doesn't want his two sons to go out to greet him, in case Li Xiaogong and one of them get together, it will be really ugly, what he hopes most is to send his daughter Li Xiuning to greet him, of course, if he really sends Li Xiuning to greet Li Xiaogong, it will become a joke in the world, not to welcome people, but to insult Li Xiaogong.

"The two cousins are polite!" Li Xiaogong returned the salute.

"My father has already set up a banquet, bow to my cousin! I wonder what my cousin thinks? After the three of them said a set of kind words, Li Jiancheng asked.

"Don't dare to have Uncle Lao wait for a long time! Built, the people of the world, please! Li Xiaogong replied politely.

"Cousin, please! The carriage is ready! Li Jiancheng opened his mouth and said, Li Shimin smiled next to him and didn't say anything, no matter how discordant the two brothers were at this time, he would not go to dismantle the stage and let others laugh at him.

Li Xiaogong boarded the carriage prepared by Li Valve, and drove to Li Valve's mansion in Chang'an City (in essence, it is still Daxing City, for the convenience of everyone's reading, it is still called Chang'an City), and the spies of the major forces in the world are paying attention to Li Xiaogong's dynamics, watching the carriage carrying Li Xiaogong slowly leave. There is no way, now Li Xiaogong can basically be said to represent a general trend in the world, basically who he supports, who wins the world is likely to increase the probability of nearly eighty percent, and now that he has returned to Li Valve, the major forces will naturally pay attention to his attitude.

After arriving at Li Valve's mansion, Li Yuan, the owner of Li Valve, had already greeted him at the door, and after a few people were polite, they walked into Li Valve's mansion. The house was already full of lights and lively, and a banquet had been set up in the main living room, and after Li Yuan led Li Xiaogong in, he sat in the first place of the guest seats, and then a group of people ate and drank. Of course, the banquet in the Sui and Tang dynasties is different from now, now it is a group of people gathered in a venue, ten people at a table, heavyweight guests and the host sit at the main table, the Sui and Tang dynasties used a meal system, simply put, it is a small table, the host does the middle position, the right hand side of the host begins to be the guest, the left hand side of the host is the person who has accompanied the highest position, and then the back position is divided according to their own status.

The banquet in the world is like a bird, and the banquet in ancient and modern times is even more like a bird! Looking back on the past and looking to the future! The core idea is nothing more than eight words, with high emotional intelligence, put on high risks for others, pat others on the back, and let the person being photographed achieve their goals unconsciously, and those with low emotional intelligence can only watch others perform, and drink with their heads covered, and in the end they drank a lot of wine, but they didn't do much.

During the drinking party, Li Yuan and Li Xiaogong kept testing each other and playing Tai Chi with each other, and it was not suitable for the rest of the people to interject, so they could only sit and watch the two perform. Even at the end of the cocktail party, Li Xiaogong was not set up by Li Yuan to say anything effective, and Li Yuan was also tight-lipped. When the two said goodbye to each other at the end of the banquet, it is unknown whether they scolded each other for being old foxes in their hearts.
