Being in the world's first city in the 7th century, Ding Yi was very excited, and through the Jinguangmen doorway, the bustling pedestrians looked at Ding Yi's brothers and sisters curiously. The three little ones were roughly stuffed into the backpack by Ding Yi, revealing the three dog heads!!

Two people, three dogs, ten eyes looked around, and the only remaining Xi'an in later generations was the incomplete city wall and some palace ruins. Excitement, excitement, and all kinds of complicated feelings filled Ding Yi's chest. Ding is a little grateful to the system, and he traveled to Chang'an more than 1,300 years ago, and saw the grandeur that later generations could not see.

This is a crystallization of the wisdom of the ancients, the product of the collision of various ideas of Taoism, Buddhism, Confucianism, and ancient craftsmen.

Ding Yi's later life is not considered to have traveled all over the historical sites of Xi'an, but he also understands this.

The area of Tang Chang'an City is 84 square kilometers, consisting of the outer Guo City, the palace city and the imperial city. The streets in the outer Guo city crisscross and divide one hundred and eight lanes. In addition, there are artificial gardens such as the East Market, the West Market and the Hibiscus Garden. The overall planning of the city is neat and the layout is rigorous, which can be called a model of ancient Chinese capital. And the "Lifang system" is the result of the Tang inheriting the capital of the Sui Dynasty. "The capital of the Sui Dynasty at the beginning was the original Han Chang'an City, with the country's political and economic prosperity, Emperor Wen of the Sui Dynasty gave up the Han Chang'an City, and re-chose to build a new city on the southern slope of Longshouyuan in the southeast of it, which is what we call 'Daxing City'. Since Daxing City was newly built, a problem of order was highlighted in the design process, and the rulers emphasized imperial power in the process of building the city, implemented strict central axis symmetry, and took the 'fang' as a unit to facilitate the resettlement of residents and the layout of bureaucracy. The Tang Chang'an City, is the Sui Daxing City on the basis of expansion and repair, the city is divided into three parts: the palace city, the imperial city and the outer Guo city, of which the palace city is the king, is the emperor's place; The imperial city is where the central yamen is located; Waiguocheng, on the other hand, is the residential area of the subjects, and it implements the 'lifang system', and the neighborhood is divided by roads, which still takes a form similar to Luli, much like a modern community.

The wisdom of the ancients is something that we modern people cannot understand, we are all stepping on the shoulders of the ancients to develop rapidly, and the modern peaceful, stable and harmonious society is the foundation for our stable and rapid development.

Based on the ancients, take history as a mirror.

Each square in Chang'an City is a regular and standard rectangle, which is simply an incredible thing in the eyes of today's people. In the arrangement of the lane, with Suzaku Street as the central axis, the left and right are also very symmetrical, the east and west of the street, the location of the street and its shape, and the size of the area are all equal to each other, and the left and right are all symmetrical. And 108 squares also have symbolic meanings: 108 squares correspond to 108 stars that imply 108 gods (such as the 108 generals in "Water Margin"); Thirteen squares are arranged in the north and south, symbolizing "a year with a leap"; There are four squares in the east and west to the south of the imperial city, symbolizing the "four seasons of the year"; To the south of the imperial city, the north and south nine squares symbolize the so-called "Wangcheng Jiukui" recorded in the book "Zhou Li".

Judging from the size of each square, the area of the east and west sides of the Imperial City and Miyagi is larger, and the area of the south of the Imperial City is smaller. The rise and fall of each fang also rose and fell with the changes in the politics of the Tang Dynasty. For example, in the early Tang Dynasty, when Taiji Palace was used as the imperial palace, the squares on the east and west sides of the imperial city were relatively prosperous; When Gaozong went to Ruizong, with Daming Palace as the center, the southern squares became prosperous areas; When Xuanzong was in power, he moved to Xingqing Palace, and the neighborhoods around Xingqing Palace prospered. Although the squares of Chang'an City are different in size and prosperity, their structure is basically the same.

"Whew... It's exhausting. Ding Yi, who had walked from the golden light to the Vermilion Bird Gate, couldn't help but sigh when he looked at the imperial city.

In the past few years, there have been Li Shimin and Empress Changsun's family, and I really want to enter to have a look, but I don't know if I can buy tickets with the palace guards.

But seeing the strange eyes of the soldiers defending the city, and the move of rushing over at any time, Ding Yi felt that it was better to change the course and slip away first!

As soon as I walked through the legendary West City, it was simply a center of cultural exchange between China and foreign countries, although those people from Goguryeo, Tibetan, Silla Baekje and even further countries lived obscenely in such a place where the central idea of "non-our race must have different hearts", but it was undeniable that various ideas were exchanged and collided.

I remember that there was a curfew in Chang'an at this time, and I had to find a place to live first, but I had no money, so I couldn't help but think of Old Man Bai. He's from Chongde Fang, isn't he...?

"Erya, the old man who invited us to his house on the way is in Chongde Fang, right?"

"Yes, brother, do you want to visit him?" Erya was deeply suspicious of this brother's memory→_→

"Let's go, or we'll have to get into the game tonight."

"Bureau? What's that? ”

……

I inquired all the way into Chongde Fang, first went to the Bai family to see the situation and sell the mirror, and then bought a house by myself, as for that bold idea, I had to come step by step...

I am innocent now, and no matter how much I think, it is in vain.

Finding the Bai Mansion and letting the concierge enter the report, it should be that the old man Bai has explained, otherwise it would be very embarrassing to visit rashly like himself.

After a while, I saw Old Man Bai personally greet him.

"Haha, Brother Ding, I knew you would come, please please."

Ding Yi didn't expect Old Man Bai to be so enthusiastic, and he actually ran out to greet him in person. But if you think about it, you will be relieved, the scholars of this era are high, not to mention the old white-headed businessmen, Shinong businessmen and businessmen have changed the original meaning and original intention under the interpretation of a group of corrupt Confucians who make full use of their professional knowledge. Woe to you!

"Uncle Bai is too high-minded, how can I ask you to come in person. The kid doesn't know the etiquette for the first visit, and I hope you will forgive me if there is any offense. ”

Regarding Mr. Bai's enthusiasm, Ding Yi still had to answer politely and sincerely. You can't let others feel that you are arrogant, and you have to do business with others later!

Dragged the old man Bai into the front hall, and the second and third little ones were also taken to the side hall, Ding Yi looked at the "tea" brought by the maid and felt powerless.

"Uncle Bai, the kid took the liberty to visit, disturb the boss, my brother and sister are really unrelated in this Chang'an City, I heard that you have a few spice shops before, and the kid is here for this." Ding Yi felt that it was almost there, and went straight to the point.

"Oh, please also ask Brother Ding for advice." Bai Xiang was a little puzzled when he heard this, did he want to do business with me?

"Boy, there is something here, I believe that Uncle Bai will understand after reading it!" As he spoke, he took out a round mirror with a diameter of 5 cm from his bag, and the plastic shell on the outside had been removed by Ding Yi.

"Oh, then I'm going to have to see it." After speaking, he took Ding Yi and handed over the mirror.

Bai Xiang suddenly saw a middle-aged man who was a little greasy, with a beard and a bun. The mole with the size of a yellow grain of rice next to the corner of the mouth is even clearer.

"Brother Ding, this... This...... Is this made of glass? Bai Xiang was shocked.

"Uncle Bai, this is the ancestral mirror of the kid, now my brother and sister have nowhere to stay in Chang'an, and they are penniless, and they are fortunate to meet Uncle Bai outside Chang'an City. I admire Mr. Bai very much, and having such a big family business is even more friendly, so the kid came to visit to sell this thing. I can trust Mr. Bai, so he came. "To make a man crazy, you have to inflate it. Ding Yi knew very well that he wanted to maximize the benefits of these mirrors, so he slapped the white old man's ass mercilessly.
