Chang'an City, the capital of the Tang Dynasty, was named Daxing City in the Sui Dynasty.

After the Tang Dynasty, the population gradually grew to one million, making it the first city in the history of the world to reach a million people.

In the center of the north of Chang'an City is the palace city, where the emperor and the royal family eat, live and drink. To the south of Miyagi is where government officials work. Beyond the palace and the imperial city is the outer city, which is the CBD business district and residential area.

The business district is divided into the East Market and the West Market, which stand opposite each other, and in the middle is Suzaku Street, which connects the three Miyagi cities, running through the north and south.

The West Market gathers 220 lines of dancers, wine shops, clothing stores, quyi juggling, cabinet shops, pharmacies, jewelry stores, iron shops, silk shops, orchids, etc.

The East Market is relatively close to the Imperial Palace, and it is not as flamboyant as the West Market, which looks serious and restrained.

It is said that modern people buy goods, saying that they are buying things, and this is how they come about, which is related to the east and west markets of the Tang Dynasty.

Chang'an has developed to the peak stage, is the center of the world, glowing with brilliant light, attracting a large number of foreign envoys and worshippers.

As the political and cultural center of the Tang Dynasty, Chang'an is like a gentle and affectionate outstanding beauty, showing the world all the advantages in his bones: self-confidence, openness, atmosphere, tolerance, progress, touching national spirit, and admirable cultural highland, which has made the world proud of it for thousands of years.

This capital can be charming and prosperous, admired by all countries, all thanks to the political clarity, economic recovery, and cultural prosperity of Tang Taizong Li Shimin during the reign of Li Shimin in the early years of the Tang Dynasty, which is known as the "rule of Zhenguan" in history.

Li Shimin, the founder of this great situation, was almost killed by the ferocious enemy on the battlefield several times, and now that the world is calm and there is no war, when he returns to the imperial court, his elder brother Li Jiancheng and younger brother Li Yuanji have brought him troubles, and the dangers faced by the war are as bad as the omen, and even the treacherous atmosphere of the waves exceeds the ferocity of the war, so that he has no chance to shine for thousands of years at any time, showing his true colors as a male god through the ages. Moreover, the prosperity of Chang'an described earlier may no longer exist.

Behind this wonderful prosperity, there is a lot of bloody killing and heartbreaking.

As the real founder of the Tang Dynasty, Li Shimin, but he can't be the emperor, there are many people who cry out for him, Li Yuan, who sits on the dragon chair and holds the right to speak, but resolutely insists that the crown prince is the eldest son Li Jiancheng, even if Li Shimin's credit is great to the sky, you are not the eldest son of the Li family, you have to stand aside, and the throne has no part for him. If he, Li Shimin, wants to, he can only be a pipe dream. Li Yuan thought that if he stubbornly insisted on it, he would be able to stabilize the situation, and the brothers would naturally understand this rule and tradition, and they would not kill each other and cross the thunder pool for the sake of the throne.

People have always thought very beautifully, but the reality is always heart-wrenching. Li Yuan's three sons are not fuel-efficient lamps, and they can exist in peace and quiet according to his wishes.

Although Li Jiancheng is the crown prince, he is always afraid that Li Shimin, who has outstanding military achievements, is too dazzling, and there are many people who serve him, so he twists into a rope and rudely pulls him down from the crown prince like a tethered animal, and then throws him to the underworld, squinting and imagining such an ending, it makes his heart crack into a chrysanthemum, it seems that only by getting rid of Li Shimin, who has made great contributions to the smooth establishment of the Tang Dynasty, can he feel at ease, sleep without nightmares, and wake up to eat it will be fragrant.
