Yan Zhenqing came with a worried mood, but when he left, his mood was not ordinarily good, Ang Lee's comfort completely reassured him, and made him believe that the officials of the Tang Dynasty are still mostly upright, and the traitors are just a handful, and this handful of traitors will be defeated sooner or later, and they can't afford to make much waves.

And after sending Yan Zhenqing away, Li An's mood was also a burst of emotion, he could see that there were still many loyal ministers like Yan Zhenqing, and people such as Yang Guozhong and Li Linfu were only a few after all, and as long as the Tang Dynasty had a large number of honest and loyal ministers, the Tang Empire would definitely have hope, and with his own support, the hope of the Tang Empire's eternal prosperity would be greater.

Although the Wanli Transsion plan encountered great difficulties, but under the efforts of Ang Lee, a very thorny problem was finally solved, after sending Yan Zhenqing away, Ang Lee already had an idea, and before going to bed at night, he straightened out this idea, and the next morning, when he went to the R&D center, he solved the problem in a short time.

Sports protective gear is still being made, and Ang Lee needs to go outside the city to investigate and determine the route for the emperors and grandchildren to go out, and this route must meet certain conditions.

First of all, safety is definitely the most important, this road must not be too dangerous, if there is a risk of falling off the cliff at any time, it is absolutely impossible to walk, there are too many thorns on the road, it is easy to scratch the clothes.

Secondly, there should not be a large number of pedestrians along the road, if there are all people around, then there will be a series of safety problems, and for safety, many people must avoid it, so there is a suspicion of disturbing the people.

There must be a lot of different animals and plants along the way, so that it is more meaningful to come out to class, otherwise, if you can't see anything new along the way, then what's the point of coming out to class.

The last one is that the distance should not be too long, the physique of these emperors and grandsons is very ordinary, if it is a long journey, it is estimated that back pain is inevitable, and even, halfway directly can not walk, so it will be a big trouble.

Although Li Ang is also relatively clear about the environment outside the city, however, because he doesn't go there often, and every time he goes outside the city, he is a casual observer, and he doesn't carefully observe the situation outside the city, so it is also necessary to go outside the city to take a look in person this time.

The scenery around Chang'an City is still very good, after all, this is also a very important condition for the location of the capital, if the nearby scenery is not good, the ruler will not build the capital here?

The geographical characteristics of the vicinity of Chang'an City are mainly composed of many water systems and soil plains, in addition, there are some rivers that arise along the water system.

As long as there are eight famous rivers in the water system of Chang'an City, also known as the eight rivers around Chang'an, among them, the Weishui in the north of the city is the most important river, which can also be called the main stream, and the remaining seven are all tributaries of the Weishui, which will eventually flow into the Weishui.

The most famous is the Jing River in the northeast, after all, because there is a clear dividing line where this river and Weishui are combined, and the clear water and the muddy water do not interfere with each other, which is very magical, which is the so-called Jingwei distinction.

The Bahe River on the east side of Chang'an City is also famous, and the main reason why the Bahe River is famous is because of a bridge over the river, that is, Baqiao, a very inconspicuous stone bridge.

Historically, when many people said goodbye, they were carried out on the Baqiao, and many poets wrote famous sentences here that will be praised by future generations.

For example, Li Bai once wrote, 'Every year the willow color, the Baling is sad goodbye.' Zeng Shen also wrote, 'The first journey is not early, and the stay is at the bridgehead. 'Liu Yuxi's' conscription is out of the way, looking back on the injury. 'Li He's' Ba Shui Lou boat ferry, the camp gate is open with fine willows. 'Li Shangyin's' Bashui Bridge leans on the Huabiao, and there is usually an eastern tour in February. "Li Yi's" willow contains smoke and spring on the shore, climbing and folding for pedestrians every year, if the good wind borrows the low branches, don't send green silk to sweep the road dust. ’

In short, many people in the Tang Dynasty bid farewell by the Baqiao, especially many famous poets, who wrote famous sentences through the ages when they said goodbye here, which greatly improved the popularity of Baqiao, and even raised the fame of Bashui.

That is to say, among the eight rivers of Chang'an, in addition to the great fame of the main stream of the Wei River, the tributaries Jing River and Bahe River are also very famous, while the fame of the other five rivers is relatively small, and it cannot be compared with these three rivers at all.

In addition to the river, there are many soil plains around Chang'an City, in fact, it should be called the mound, which refers to the Loess Plateau area of China, due to the long-term rain erosion and the formation of a piece of highland, steep around, but the top is very flat.

Such a special terrain is called a plateau, and in the vicinity of Chang'an City, there are many plateaus like this formed by rainwater.

There is Xianyang Yuan in the north of the Wei River, Chang'an City itself is located on the Longshou Plain, there is the Tongren Yuan on the east side of the Bahe River, there is Leyou Yuan in the south of Chang'an City, and then there are Fengqi Plain, Shaoling Plain, Bali Yuan in the south and southwest, these are all located between the Wei River and the Chan River, that is to say, the original between these two rivers is the most, and the most famous, such as the Longshou Yuan is the territory of the capital, and the Leyou Yuan is a famous place.

Between the Bahe River and the Chan River, Bailuyuan was formed, and its fame in later generations was greater, after all, this was once filmed into a TV series, and it was impossible to think about it if it was not famous.

Located in the southern part of the capital, between the Kagawa River and the Wei River, it is the watershed of these two rivers, the eastern part of the Shenheyuan is the famous Fan River, and the western part is the Ojuku River.

In the west, between the Lihe River and the Feng River, there are Biyuan, Xiliuyuan, Gaoyangyuan, in addition, in the distance of Chang'an City, there are more Yuan, however, because the distance is too far, no one pays attention.

And because the river has been impacting the loess for a long time, over time it has formed a river on both sides of the river, which can also be understood as an impact plain, but these small plains are sandwiched between two or more soil plains, which appear relatively narrow and long, but the scenery is very beautiful, and these rivers are also a place for many celebrities to refuge, which can be understood as villas.

The most famous is located in Fanchuan between Shenhe Yuan and Shaoling Yuan, this location is not far from the capital, the scenery is also very beautiful, it is a very good villa area, many great poets have put their villas here, of course, the villas of this era are also relatively simple, basically grass and wood structure houses, among them, mud and grass houses are the most, because this type of house is relatively low cost, easy to build, and brick and stone structure houses are too expensive.

In the Loess Plateau, there is no shortage of loess, there are many trees and plants, and it is too easy to build a very ordinary villa outside the city with good scenery.

Of course, for the wealthy, living in a civil structure house is a little too aggrieved, and it is natural to spend some money to build some brick and stone houses, which look more decent and less likely to be damaged.

For example, the Weidu clan in the south of the city, their villas are all brick and stone structures, and there are many wealthy nobles who also build villas here.

Because Fanchuan is an alluvial plain formed by the river, so, if the middle is a river, it is too convenient to take water, many villas are built on the riverside, only need to dig a ditch, you can lead the river water to your own villa area, so that your villa area has both rockery trees and smart water flow, so that the scenery will be more beautiful.

Among all the originals, only Leyouyuan and Longshouyuan are in the interior of the capital, among them, the area of Longshouyuan is very large, including the imperial palace and many areas in the city, and the area of Leyouyuan is relatively small, however, the terrain of Leyouyuan is very high, standing on Leyouyuan, you can overlook Qinglong Temple, Qujiang Pond, Big and Small Wild Goose Pagoda, in short, it is a good place to enjoy the beautiful scenery.

Historically, once, Emperor Xuan of the Han Dynasty and Empress Xu traveled here, very infatuated with the gorgeous scenery here, so that they could not think of returning, and later, they built the Leyou Temple here, and Leyou was originally named after it.

As for Shaolingyuan, it was originally called Du Lingyuan, it was the cemetery of Emperor Xuan of the Han Dynasty Liu Xun, and later Emperor Xuan's Empress Xu was buried in Dulingnan, because the mausoleum was smaller, it was called Shaoling, and then it was called so.

In addition, Du Fu, a famous poet of the Tang Dynasty, has been living in Shaolingyuan, so he is called Shaoling Yelao, or directly called Du Shaoling.

There are so many good places in the capital, even Li An, who doesn't work too hard, can't visit them all, let alone ordinary people who are tired of running for their lives, as for the imperial grandson who is locked up in the palace all day, he doesn't know much about the situation on the outskirts of the capital.

Ang Lee is going to take the emperors and grandchildren to play in the wild this time, also so that they can see more of nature, which is also very beneficial to their growth.

And because there are too many factors to consider when traveling to the emperor and grandson, Li An must investigate first and determine the route of travel, it is best to use a day to go to a few more places, and at the same time, between every two locations, it needs to be able to open to traffic, otherwise, if you run on two legs one by one, it will be too tiring, and if you pick up and drop off with a vehicle for every two locations, you can save a lot of trouble, and only the most valuable road sections and scenic spots will let them come down and walk slowly.

When he went out of the city, Li Ang went out by car, and there were not many people with him, only a dozen people, so the goal was relatively small, and the efficiency of travel was relatively high.

Li An went out from Mingde Gate, all the way along the paved cement road to the south, after the successful development of cement and concrete, the roads inside Chang'an City and the main roads outside the city were all replaced with cement roads, so that no matter what kind of vehicle, walking will save a lot of effort, especially when encountering rainy weather, the road is no longer muddy, and the speed of transportation will not be affected at all.

After leaving the city, Li An went straight to Fanchuan, because in the east of Fanchuan is Shaoling Plain, west is Shenhe Plain, there is a river in the middle, the scenery is very beautiful, there are many villa areas, the number of various animals and plants, naturally there are a lot, in this area to play, is the most effective.

"Alright, park."

Li An sat in the car and enjoyed the scenery on both sides of the road, and suddenly saw Du Fu's villa, so he stopped the car.

In fact, if it weren't for Du Fu himself, Li An would really not be sure that the simple house in front of him was actually Du Fu's home, such a shabby building, I am really sorry for the image of Du Fu as a great poet.

However, this is also a matter of no way, it is not easy to live in Chang'an, all kinds of prices are too expensive, the price of houses in the city is too high, if you buy one in the early years, it is okay, but now the house price has risen too much, even if Du Fu works hard, he can't afford it, although the editor-in-chief's salary is not bad, occasionally write a few poems, and earn a little money, but these money want to buy a house in Chang'an City, it is still very difficult, and he has no hope in this life.

In addition, Du Fu has a family of five, his wife and three children are the masters of just eating, only Du Fu earns money alone, and one person earns money to support a large family, this pressure can be imagined.

Of course, the high house price is only one of the reasons, and another reason is that Lao Du likes beautiful places, so that he can be more inspired and feel more comfortable.

To say that the aristocracy goes out to ride a car that has not been on the market for a few years, the next is a carriage, and riding a horse is also more face-saving, and Lao Du chooses to ride a bicycle, which is the most shabby one, but this means of transportation is the cheapest, especially after mass production, the price is more and more close to the people, so that it soon became the standard configuration of poor families, as long as there is a little money, they will choose to buy a substitute, although it requires the strength of the legs, but it is much more labor-saving than walking directly, and the speed is much faster, If it weren't for this simple and cheap means of transportation, it is estimated that Lao Du would have to go to the city to rent a house to live, after all, he needs to go to work almost every day, and he can't rest for a few days a month, if there is too much delay on the road, it will be too cost-effective.

In addition to seeing Du Fu standing in the yard for a walk, Li An also saw a brand-new bicycle next to the courtyard, the vehicle was placed in the yard, the Tang Dynasty of this era, the public security environment is still very good, and generally will not encounter thieves, one side of the vehicle is an old locust tree, which seems to be at least thirty or fifty years old, and Du Fu's age is about the same, and it does not look like it is transplanted, it seems to have been growing here.

The whole courtyard is neither big nor small, in addition to this big locust tree, there are several small locust trees, in addition, there are some flower trees dotted.

There are not many houses, there are only three rooms on the front, which are the main houses, which are made of wood and earth, and even the top panel is made of wood, and the top is covered with a layer of thatch to prevent rain leakage.

There are also two small houses on the left and right sides, both in length and height, which are much shorter than the three houses on the front, and the materials of the houses are more inferior, such as the walls are dirt, only the bottom has three layers of stone, otherwise, the house is easy to collapse when it rains heavily.
