Although Luoyang has a 'history of building the capital' early, Luoyang City is a very young city.

Today's Luoyang City was built after Emperor Yang of Sui ascended the throne. The ruins of the capital city of Luoyang have long been lost in the long river of history. Li Mu has read Li Tai's "Chronicles of the Territory", 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. Immediately, hundreds of thousands of adult men were recruited to dig trenches, connect Changping and Jijun from Longmen to the east, arrive at Linqing Pass, cross the Yellow River, and then extend to Junyi, Xiangcheng, and finally Shangluo, so as to set up checkpoints to strengthen the defense around Luoyang. At the end of the first year of the Great Cause, Emperor Yang of Sui officially issued an edict to build Luoyang City.

At that time, the main responsible for the construction was Shangshu Ling Yang Su, the master craftsman Yu Wenkai, etc., in the east of the old king of Luoyang, the west of Luoyang City of the Han and Wei dynasties, and the site was selected for construction. There were 2 million envoys, including 700,000 who built palaces and cities, 100,000 who built palaces and walls, more than 800,000 earthworkers, and more than 100,000 carpenters, bricklayers, metalworkers, and masonry. Such a large-scale construction is far ahead of the ages.

Emperor Yang of the Sui Dynasty was very happy, while building Luoyang City, on the other hand, he dug the Grand Canal, requisitioned more than 100,000 men and women from Henan counties, excavated the Tongji Canal, and diverted the valley water and Luoshui from Xiyuan to the Yellow River, and from Banzhu to the Huai River, connecting the waterways. A total of nearly 3.5 million people were conscripted before and after, and such a large-scale conscription also left a bane for the final fall of the Sui Dynasty.

But no matter what the result is, Luoyang City and the Grand Canal, Emperor Yang of Sui did a good job. It is also recorded in the history books, saying that when Luoyang City was built, "the manufacture was quite poor and luxurious, and the capital of the previous generation was more than Yan". From construction to completion, it took a total of 18 months, and also set a record for the speed of city construction in all dynasties. The strength of the Sui Dynasty at that time can be seen from this incident. The same thing, Li Shimin now, can't even think about it.

When Li Mu saw this paragraph of the record in the "Chronicles of the Ground", he had doubts. At that time, when Emperor Yang of the Sui Dynasty built Luoyang City, Chang'an City was not unlivable. Just look at the current Chang'an City, after the chaos at the end of the Sui Dynasty, the Tang Dynasty set the capital of Chang'an, and everything was running as usual, indicating that Chang'an City at that time must be able to be used as the capital. In this way, it can be concluded that Emperor Yang of Sui must have other purposes in building Luoyang City.

He discussed the matter with Li Tai, and Li Tai gave him an answer, and in order to compile the Geographical Chronicles, Li Tai made a lot of effort to study the evidence.

Throughout history, the reason why Luoyang has been favored as the capital city is also very simple to say. As early as the Xia Shang era, the world was divided into Kyushu, and Luoyang was just in the center of Kyushu. The Duke of Zhou chose this place to build the capital 'Luoyi', which is to take this meaning, Zhou Tianzi occupied the 'middle of the world', showing orthodoxy and showing the supreme dignity of the emperor.

In addition, the construction of the capital city in the middle of the world also facilitated the rapid access of government decrees, local pilgrimages and tributes, which was also very beneficial to the rule, and achieved a state of the best of both worlds in terms of ideology and practical utility.

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

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

For the Central Plains Dynasty, the scope of domination of the world is roughly the so-called 'land of Kyushu'. If you occupy the land of Kyushu, you can declare your domination of the world. The Qin, Han, Sui and Tang dynasties, these great unified dynasties, after dominating the world, will face a problem: when occupying Kyushu, how to resist foreign enemies?

Where does the enemy come from? To the east and south is the sea, and the enemy is either from the north or from the west. If you choose Luoyang, the capital of Luoyang, which is 'in the middle of the world', by the time the enemy comes, most of the country has already fallen. The Son of Heaven, defending the Central Plains, in order to resist foreign invasion, is a better choice for Chang'an, which is located relatively closer to the northwest.

And when the country is stable and all sides are subdued, the military pressure is reduced, and the superiority of Luoyang City will be reflected. During the reign of Emperor Yang of the Sui Dynasty, the prosperity of the emperor 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's succession, whether it was Tubo, Tuyuhun, Turkic, Goguryeo, etc., they were all beaten to the ground, and they could not pose a fatal threat to the powerful Sui Dynasty, so it was reasonable for Emperor Yang of Sui to want to move the capital.

In addition to the great joy, there is also a practical reason.

The Sui Dynasty set the capital of Chang'an City, and after the opening of the emperor's prosperous era, the population reached its peak. The 800-mile Qinchuan River in Guanzhong is limited, and the situation of "narrow land and many people" has led to the fact that the grain in Guanzhong is far from being able to meet the needs of the huge and increasing number of officials, garrisons, and the new population, and the food supply has become difficult. The Tang Dynasty set the capital of Chang'an for ten years, and in the past one or two years, this problem has appeared, and the reason why it has not reached the serious level of the Sui Dynasty is because of the chaos at the end of the Sui Dynasty, a large number of people died, and if there was still a population during the Sui Dynasty, there would have been a shortage of food.

Luoyang is different, after Emperor Yang of the Sui Dynasty repaired the Grand Canal, the grain in the south can be transferred to Luoyang, and it can be transported to Luoyang, which is labor-saving and has little loss. However, when transferred to Chang'an, it had to be transferred to Chang'an by land to bypass the Sanmen natural insurance, which not only limited grain transportation, but also time-consuming, and the gains outweighed the losses.

Therefore, Emperor Yang of the Sui Dynasty moved the capital, although there was a great side of great joy, but it was not completely mediocre.

As a newly built capital, the various plans are more novel than the Chang'an City built hundreds of years ago. The streets are wider, more sensible, and even the drains are clearer. 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 backwardness of design concepts, sometimes cannot be made up for by decoration.

In addition, the topography of Luoyang City also determines that it will not be the same as the pattern of Chang'an City. (Helpless anti-theft, refresh after 20 minutes)

Chang'an City is the east and west city, the east city and the west city, which are symmetrical along the central axis. However, Luoyang City was blocked by Luoshui, and the city was naturally divided into two sections, north and south. Therefore, Luoyang does not have the east city and the west city, only the south city and the north city, with Luoshui as the boundary, the south city is equivalent to the west city of Chang'an City, and most of the people live there. Nanshi is also equivalent to the west market of Chang'an City, selling most of the cheap items. The northern city is the opposite, the area of the northern city is only about half of the southern city, next to the imperial palace, is a gathering place for the powerful, more extravagant than the eastern city of the Great Wall. In the east city of Chang'an City, you can live if you have money, but in the north city of Luoyang City, you can't have money, you must have an identity.

The mansion given to Li Mu by Li Shimin, according to the sketch, is a mansion located in Lide Fang, Beicheng. Located in the north of the city, the location is not bad, not to mention that this Lide Fang is also west of the palace and south of Luoshui, in the words of Li Mu's previous life, this is a river-view house in the second ring road, such a high-end wet area in the city, what is not satisfied, what do you want a bicycle.

The mansions he saw along the way were all luxurious, and Li Mu concluded that the mansion in this location would definitely not be bad, and he was in a very good mood. Come to think of it, Li Shimin will not give too bad a place, he should be able to move in with his bag, and he doesn't need to take care of it.

The happy mood came to an abrupt end when Li Mu found a 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, and three big characters are clearly written - "Tiance Mansion".

Is Tiance Mansion in Luoyang?

Li Mu's head was full of question marks, in his impression, Tiance Mansion should be in Chang'an City. Could it be that it is the butterfly effect again, because of his own appearance, which changed history? Li Mu got into the car, took out Li Tai's "Chronicles of the Earth", turned a few pages, and really found the record of Tiance Mansion for him. In the fourth year of Wude, Li Shimin destroyed Wang Shichong, and Li Yuan was named General Li Shimin Tiance and allowed to open the mansion on the spot. Li Shimin conquered Lide Fang and built Tiance Mansion, which was not officially abolished until the first year of Zhenguan and the change of Xuanwu Gate. If that's the case, it's normal for Tiance Mansion to be in Luoyang.

After the abolition, the house naturally could not be demolished, and it has survived to this day. Looking at the moss at the door, it is true that no one has been here in years. Li Mu reached out and touched the door, a thick layer of dust and moss mixture, sticky and dirty. However, the plaque of 'Tiance Mansion' on the door is shining, and I don't know what material it is made of. Li Mu looked up for a while, and found that it was greasy, not a problem with the material, but someone had wiped it recently, don't think about it, it must be Li Shimin's intention. He was going to give this mansion to himself, and he deliberately asked someone to wipe the plaque so that he knew what kind of place it was.

Interesting? Li Mu sneered speechlessly, naïve!

"Husband, this is Tiance Mansion, was Your Majesty's Mansion back then? It's not appropriate for us to live here, right? Bai Qiaoqiao opened the curtain and looked at it, and said with some concern.

"What's wrong? We didn't rob it, it was given by His Majesty, and there is a map drawn by His Majesty himself as proof. Li Mu shook the sketch in his hand, folded it and handed it to Bai Qiaoqiao: "Put it away, if Your Majesty is looking for trouble in the future, we have to leave some evidence." ”

Bai Qiaoqiao put it away and asked again, "Do you really plan to live here?" What about the plaque? ”

"In the future, this will be our house, and the plaque will naturally have to be replaced." Li Mu asked someone to bring a ladder, climbed it himself, called someone to help, and got the plaque down together.

The plaque has come down, and it's a question of where to put it. After all, it is the plaque of 'Tiance Mansion', which is of great significance, and it will definitely not be possible to throw it away. Send back to Chang'an? It definitely won't work, Li Shimin can find someone to wipe the plaque clean and put it here, which means that he doesn't want to take the plaque back, so what does he mean?

Li Mu glanced at this plaque, pondered for a moment, and asked, "Daughter-in-law, did you bring the original plaque of the Zhulu Hou Mansion from our family?" ”

"It's a few pieces." Bai Qiaoqiao wrenched his fingers and calculated: "The earliest Zhulu Hou Mansion, and later the phoenix."
