Although Luoyang had a "Capital History" early on, Luoyang City is a very young city.

The Luoyang city was built after Emperor Yang of Sui ascended the throne. The ruins of Luoyang's capital have long been destroyed in the long river of history. Li Mu read Li Tai's "Guodizhi", which records that in the first year of Emperor Yang of Sui, twenty-five years ago, Emperor Yang of Sui, who had just succeeded to the throne for four months, inspected the terrain of Luoyang City. Then, hundreds of thousands of adult men were recruited to dig trenches, connecting Changping and Jijun to the east from Longmen, arrived at Linqing Pass, and then extended to Junyi and Xiangcheng, and finally arrived at Shangluo to set up checkpoints to strengthen the defense around Luoyang. At the end of the first year of Daye, Emperor Yang of Sui officially issued an edict to build Luoyang City.

At that time, the main responsible person was Yang Su, the Minister of State, who was the master craftsman, Yu Wen Kai, and others, who were located in the east of the former royal city of Luoyang and the west of Luoyang City in the Han and Wei dynasties. He was appointed to build a site. He was 2 million people, including 700,000 people who built a palace city, 100,000 people who built a palace wall courtyard, more than 800,000 people who worked in the same way as the geotechnical workers, and more than 100,000 people who worked in carpenters, tiles, metalworkers, and stoneworkers. Such a large-scale construction has been far beyond the ages.

Emperor Yang of Sui was very happy with the merits. While building Luoyang City, he dug the Grand Canal and recruited more than one million men and women in Henan counties, dug Tongji Canal, diverted Gu water from Xiyuan, and led the Luo River to the Yellow River, and connected the waterway from Banzhu to the Huai River. A total of nearly 3.5 million people were recruited. Such a large-scale corvee also left the root of disaster for the final destruction of the Sui Dynasty.

But no matter what the result is, Emperor Yang of Sui did both the two things, Luoyang City and the Grand Canal. This is also recorded in historical books. It is said that when Luoyang City was built, it was "made quite luxurious and luxurious, and the capitals of the previous dynasties were no match for it." It took a total of eighteen months from construction to completion, and it also set a record of the speed of construction of cities in all dynasties. The prosperity of the Sui Dynasty at that time can be seen from this incident. Li Shimin now dared not think about the same thing.

When Li Mu saw this record in "Guodizhi", he had doubts. When Emperor Yang of Sui built Luoyang City, Chang'an City was not impossible to live. Look at the current Chang'an City, you will know that after the chaos at the end of the Sui Dynasty, the Tang Dynasty established its capital in Chang'an, and everything was running as usual, which shows that the Chang'an City at that time must be used as a capital. In this way, one conclusion can be drawn, that is, Emperor Yang of Sui must have other purposes for building Luoyang City.

He discussed this matter with Li Tai, and Li Tai gave him an answer. In order to compile the geography, Li Tai put in some effort to meticulously research it.

Throughout history, the reason why Luoyang is favored as a capital is very simple to say. As early as the Xia and Shang dynasties, the world was divided into Jiuzhou, and Luoyang was just in the center of Jiuzhou. Zhou Gong chose this place to build the capital "Luoyi" because of this meaning. The Zhou emperor occupied the "in the world", demonstrating orthodoxy and showing the supreme dignity of the emperor.

In addition, building a capital in the world will also facilitate the rapid access to government orders, and local courts will pay tribute and pay tribute, which is also very beneficial to rule. In terms of thought and practical use, it has achieved a state of best of both worlds.

So, since Luoyang is so good, why did it have to build its capital in Chang'an when the Qin, Han, Sui and Tang dynasties and founding the country?

Li Mu studied this question himself, and soon he found the answer from clues recorded in historical books.

For the Central Plains dynasty, the scope of unification of the world is generally called the so-called "Nine Provinces Land". Occupying the land of the nine provinces can declare the unification of the world. After these unified dynasties in the Qin, Han, Sui and Tang Dynasties, after unifying the world, they will face a problem: how to resist foreign enemies after occupying the nine provinces?

Where does the enemy come from? To the east and south is the sea, the enemy either comes from the north or the west. If you choose Luoyang, which is "the world's capital", when the enemy fights, most of the country has fallen. The emperor guards the Central Plains and in order to resist the invasion of foreign tribes, the position is relatively closer to Chang'an in the northwest, is the better choice.

When the country is stable and all the barbarians are subjugating, the military pressure will be reduced, and the superiority of Luoyang City will be reflected. During the reign of Emperor Yang of Sui, the Kaihuang prosperous era had reached its peak and the country was extremely rich. With the support of huge financial resources, in the early days of Emperor Yang of Sui, whether it was Tubo, Tuyuhun, Turks, Goguryeo, etc., they were beaten to the point of falling, which could not pose a fatal threat to the powerful Sui Dynasty, so it was reasonable for Emperor Yang of Sui to move the capital.

In addition to being very happy, there is also a realistic reason.

The Sui Dynasty established its capital in Chang'an City, and after the Kaihuang period, the population reached its peak. The area of ​​the 800-mile Qinchuan in Guanzhong was limited, and the "narrow land and rich people" situation caused the food in Guanzhong to be far from meeting the needs of the huge and increasing officials, garrisons, and new populations, so it became difficult to provide food supply. The Tang Dynasty established its capital in Chang'an for ten years. In the past one or two years, this problem has been revealed, but the serious reason has not reached the Sui Dynasty's severe turmoil, because a large number of people died in the chaos at the end of the Sui Dynasty. If there were still the population in the Sui Dynasty, there would have been a shortage of food.

Luoyang is different. After Emperor Yang of Sui built the Grand Canal, the grain from the south could be transferred to Luoyang, which was transported through canal, which was labor-saving and had little loss. However, when transferred to Chang'an, you had to switch to land to bypass the Sanmen natural danger. It was not only limited in grain transportation, but also time-consuming, and the loss was not worth the cost.

Therefore, although Emperor Yang of Sui moved the capital, he was very fond of merit, but it was not entirely a foolish act.

As a newly built capital, all kinds of plans are more novel than Chang'an City built hundreds of years ago. The streets are wider, the design is more reasonable, and even the drainage canals are smoother. Although Chang'an City has spent a lot of money to repair, it is still not comparable to Luoyang City. This is like second-hand houses and new houses. The backward design concept can sometimes be compensated by decoration.

In addition, the terrain of Luoyang City also determines that it will not be the same as Chang'an City.

Chang'an City is an east-west city, with the east city and the west city, symmetrical along the central axis. However, Luoyang City passes by Luoshui, naturally divides the city into two sections. Therefore, Luoyang does not have the west city in the east city, but only the north city in the south city. With Luoshui as the boundary, the south city is equivalent to the west city of Chang'an City, and most of the living people are ordinary people. The south city is also equivalent to the west city of Chang'an City, with most affordable items sold. The north city is completely opposite. The area of ​​the north city is only half of the south city, next to the palace, and is a gathering place for the powerful and nobles, which is more luxurious than the east city of the Great Wall. The east city of Chang'an City can live with money, but the north city of Luoyang City is not enough to have money, and you must have status.

According to the sketch, the mansion given to Li Shimin was a house located in Lidefang, Beicheng. It is located in Beicheng and is not bad at the location, not to mention that Lidefang is connected to the imperial palace in the west and facing Luoshui in the south. In the words of Li Mu in his previous life, this is a river view house on the Second Ring Road. In such a high-end wet area in the city, what else is there to be dissatisfied with and what bicycles are needed?

The houses I saw along the way were all luxurious. Li Mu concluded that the mansion that could be in this location would definitely not be bad, and he was in a very good mood. I think Li Shimin would not give him a bad place, he should be able to move in with his luggage, so there was no need to take care of it.

The happy mood came to an abrupt end when Li Mu found the place.

After Li Mu followed the sketch and turned right according to the marked crooked neck tree, the mansion given by Li Shimin appeared in front of him.

There is a flying white plaque hanging on the door, with two big words clearly written - "Tiance".

Is Tiance Mansion in Luoyang?

Li Mu was full of questions. In his impression, Tiance Mansion should be in Chang'an City. Could it be another butterfly effect, because of his appearance, changed history? Li Mu got into the car, took out Li Tai's "Kuodizhi", turned a few pages, and found the records of Tiance Mansion for him. In the fourth year of Wude, Li Shimin destroyed Wang Shichong, Li Yuan appointed Li Shimin to be the general of Tiance, and allowed him to open a government on the spot. Li Shimin conquered Defang and built Tiance Mansion, which was not officially abolished until the first year of Zhenguan and the Xuanwu Gate Incident. If this is the case, it would be normal for Tiance Mansion to be in Luoyang.

After the abolition, the house naturally could not be removed and remained there until now. Looking at the moss at the door, no one has been here for many years. Li Mu reached out and touched the door. A thick mixture of dust and moss was sticky and dirty. However, the plaque of "Tiance Mansion" on the door was shining brightly, and I don't know what material it was made of. Li Mu looked up for a while and found that it was not a problem with the material, but someone had rubbed it recently. No need to think about it. It must have been Li Shimin's intention. He wanted to give this mansion to himself, deliberately asking someone to wipe the plaque so that he knew where this place was.

Is it interesting? Li Mu sneered silently, childish!

"Husband, this is the Tiance Mansion. Is Your Majesty's mansion back then? Is it not appropriate for us to live here?" Bai Qiaoqiao lifted the curtain and glanced at it, and said with some concern.

"What's wrong? We didn't rob it, it was given by Your Majesty. It was proof of the map drawn by Your Majesty himself." Li Mu shook the sketch in his hand, folded it and handed it to Bai Qiaoqiao: "It's taken away. If Your Majesty is in trouble in the future, we have to leave some evidence."

Bai Qiaoqiao put it away and asked again: "You really plan to live here? What should I do if that plaque?"

"This is our home in the future, so the plaque will naturally be replaced." Li Mu asked someone to move a ladder, climbed up by himself, asked someone to help, and got the plaque down together.

When the plaque is finished, it is a question where to put it. After all, it is a plaque of "Tiance Mansion", which is of great significance. If it is thrown away, it will definitely not work. Send it back to Chang'an? It must not work. Li Shimin was able to find someone to wipe the plaque clean and put it here, which means he doesn't want to take the plaque back. So what does he mean?

Li Mu looked at the plaque, thought for a while, and ordered: "I'll keep it safe, find a carpenter... Forget it, when I have time, come in person, be careful and carry it to the warehouse."

The Jinyiwei responded and raised the plaque together, turning around and walking back.

"Inside!" Li Mu called them and took the key to open the lock on the door: "The Luoyang Marquis Mansion is behind, where else can I carry it?"

The Jinyiwei had to turn around and carry the plaque into the yard. Li Mu looked inside and saw that the yard was covered with moss. He turned around and said to Bai Qiaoqiao, "My wife, the moss is everywhere here, it must be slippery. Don't get out of the car first. I'll ask someone to clean up later. I'll pack it tomorrow and you come in and see."

"It's okay if I'm at the door." How could Bai Qiaoqiao not be curious about what the future home looks like, so she asked Jin Chen to help her get out of the car. Li Mu had to come over and take her right hand. Jin Chen held her left hand to prevent her from being slid by the moss.

Bai Qiaoqiao came to the door, and she was afraid of sliding into it, so she didn't dare to walk in. She stood at the door and looked at the main entrance, and a feeling of grandness came to her face. When Li Shimin was named General Tiance, Li Yuan had made it clear that Tiance Mansion was ranked first among the military officials and above the Twelve Guards. General Tiance is above the prince and the three dukes. Therefore, the architecture of Tiance Mansion is more than the prince system. It is half a square higher than the prince's system. If it is a little larger, it cannot be called a mansion, but it has to be called a palace.

"Husband, why am I a little nervous? Will your Majesty ask us to live here? Is it a little..." Bai Qiaoqiao approached Li Mu's ear and whispered: "It seems a bit over the rules."

"So you have to keep the map drawn by His Majesty himself, don't lose it." Li Mu heard a whispering voice behind him, and looked back. At some point, there were many people gathered here, watching from afar, whispering to each other.

Li Mu leaned into the ears of the two girls and said, "It's open and generous, your Majesty gives you, don't be so nervous, as if you're sneaking." After that, Li Mu turned around, faced the audience, bowed to the west, and whispered loudly: "I am given this mansion by Your Majesty's affection. I will live here in the future and be considered a neighbor to everyone. This is called Lidefang, right? Everyone can hear it clearly. From now on, I will change my name. From now on, I will call it Tiancefang. The plaque in the fangmen will be changed tomorrow."

"Brother, what you want has arrived." Dugu Jiu's voice came from outside the crowd, and Li Mu was overjoyed and said, "It's really timely, bring it over!"

Several Jinyiwei separated the crowd, Dugu Jiu drove in a carriage, and a new plaque was placed on the carriage.

"It just so happened that the ladder has not been removed yet, so I can use my hand to hang it up, hang it up!"

Li Mu shouted, and several Jinyiwei climbed up the ladder and hung the plaque brought by Dugu Jiu. The new plaque was covered with red silk. Li Mu pulled off the silk casually, and two big words appeared in front of everyone.

It is concise and concise, with the word "Houfu".
