A new day, a new sky appears!
【Inventory of China's ancient capitals! 】

[If you traveled through time and space to establish your own dynasty, where would you make your capital? ]

[The most common understanding is to choose the capital in the central area of ​​one's territory. ]

[It is convenient to radiate in all directions and rule the whole country. ]

【Avoid the situation where the government's orders are not smooth and the emperor is far away due to the long distance and inconvenient transportation. 】

[But besides the first instinct, choose the central area of ​​the territory. 】

[What are the other points when choosing a place as the capital of your feudal dynasty? 】

The sky screen is still playing.

Netizens can no longer hold back.

"The capital is Wuhan, because I am from Hubei!"

《Must be Chang'an! Carefully selected by our ancestors! 》

"Let's take Chang'an. It will be easier to control the Western Regions and compete with the Han and Tang dynasties, which were at the peak of martial virtue."

"Luoyang is the center of the world, and Chang'an is the secondary capital in the west."

"Don't open Kaifeng anyway. Kaifeng has no defenses, so just destroy it all at once."

The sky screen also continued to play.

[Regarding the selection of the capital, our ancestors have summarized several key points over thousands of years of history. ]

[In today's video, let's take a look at how our ancestors chose the capital of their dynasty. ]

[The decision on where to locate the capital is the lifeblood of the dynasty and is related to the fate of the country. ]

[We must guard the eight directions and control the four extremes. 】

[As early as in Guanzi Riding a Horse, it was said: "When establishing a capital, it should not be under a big mountain, but on a wide river."]

【Three thousand years ago, the Chinese ancestors knew that the location of the capital was the foundation of the country. 】

[From the division of the nine states by Emperor Yu to the unification by Emperor Qin Shihuang, from the prosperity of the Han and Tang dynasties to the transition from Ming to Qing dynasties.]

[Every capital city is a precise equation of the right time, right place, and right people. ]

[It should be like a giant turtle that stabilizes the sea and stabilizes the country, and it should also be like hundreds of rivers flowing into the sea that unite people’s hearts. ]

【A beautiful landscape is the most important factor in choosing a capital. 】

[“Shaanxi is located in the upper reaches of the world and controls the fate of the world.” This explains why the thirteen dynasties gathered in Guanzhong;]

[The economic lifeline is the lifeline of the dynasty. ]

[During the Han Dynasty, Sang Hongyang implemented the equalization of transport and controlled the national supplies through the dual capital system of Chang'an and Luoyang;]

[Yang Guang dug the Grand Canal, using 2400 kilometers of waterways to provide blood transfusions for Luoyang. ]

[The "Song History: River and Canal Records" emphasizes that "the Bian Canal is the foundation of the country", so the Northern Song Dynasty defended the lifeline of the grain transport in Kaifeng. ]

[The Dreams of the Southern Song Dynasty recorded that Lin'an "consumed 10,000 pigs every day". Such a large consumption of materials forced the capital to have a water transport network or a rich hinterland.]

[In addition to the geographical location. ]

【Cultural identity is an invisible wall. 】

【Liu Bang initially wanted to make Luoyang his capital, but because Lou Jing advised him that "Qin is surrounded by mountains and rivers, and is well-protected on all sides", he decided to move the capital to Chang'an. 】

[It is actually to use the ancient sites of Zhou and Qin to consolidate legitimacy. ]

[Emperor Xiaowen of the Northern Wei Dynasty moved the capital to Luoyang, ostensibly for the purpose of conquering the south.]

[In fact, it was to use the "Central Plains orthodoxy" to resolve the centrifugal force of the Xianbei nobles. This cultural migration was more thrilling than the geographical migration. ]]

[Military defense capability is the capital's bottom line.]

【Nanjing Stone City experienced more than 200 offensive and defensive battles during the cold weapon era. 】

[The 35-kilometer Ming City Wall has 13616 battlements, and each firing hole has been ballistically calculated.]

[From the Shang Dynasty sacrifices recorded in oracle bone inscriptions to the Persian gold coins unearthed from the Yingtianmen site;]

[From the weapons of the Six Kingdoms in the rammed earth foundation of the Afang Palace to the fingerprints of Suzhou craftsmen on the gold bricks of the Forbidden City. ]

[These capitals are not only political centers, but also melting pots of civilization! ]

[The history of the succession of the seven ancient capitals is half of the history of the evolution of Chinese civilization. ]

[Today's video will introduce the seven ancient capitals carefully selected by our ancestors. 】

[First is Xi'an! ] [The place where the royal spirit of thirteen dynasties condensed! ]

【Xi’an is located in the heart of the Guanzhong Plain, with the Qinling Mountains to the south and the Wei River to the north. It was called “Chang’an” and “Haojing” in ancient times. 】

【It is the only city in Chinese history that has been a capital for more than a thousand years. 】

[The Western Zhou Dynasty established rituals and music here, the Qin Dynasty swept across the world, the Han Dynasty opened the Silk Road, and the Tang Dynasty accepted all nations. The royal aura of the thirteen dynasties was superimposed here. ]

[The Records of the Grand Historian states: "Guanzhong is bordered by the Han River on the left and Long and Shu on the right, with fertile fields stretching for thousands of miles. This is what is called a golden city of thousands of miles, a land of abundance."]

[The core advantages of choosing Xi'an are:]

[The four passes of Guanzhong - Tongguan in the east, Sanguan in the west, Wuguan in the south, and Xiaoguan in the north - constitute a natural military fortress. ]

[The narrowest part of Hangu Pass is only wide enough for a bicycle to pass through, which is truly a case of "one man guarding the pass, ten thousand men cannot open it." ]

[Eight rivers surround Chang'an, and the Weihe River canal transport directly connects to the Yellow River. 】

【The grain stored in Taicang during the Han Dynasty was so piled up that it was rotten and inedible. ·】

[In its heyday, Chang'an City had an area of ​​84 square kilometers, and Suzaku Street was 150 meters wide, more spectacular than a modern two-way eight-lane road.]

[But making Xi'an the capital also has fatal flaws! ]

[Although the Guanzhong Plain is a vast fertile land, its carrying capacity is ultimately limited. ]

[Overdevelopment has led to the collapse of ecological carrying capacity, and the "Thousand Acres of Bamboo in Weichuan" has disappeared.]

[During the Northern and Southern Dynasties, China was no longer as prosperous as it was during the Qin and Han Dynasties.]

[Otherwise, Yuwen Tai's Wuchuan group would not have been attacked by Northern Qi for a long time. ]

[During the Tang Dynasty, Guanzhong needed to "transport 4 million dan of millet from the southeast every year."]

[The Emperor of the Tang Dynasty frequently went out to eat, becoming an emperor who chased after food. 】

[If we can't support the imperial guards, the soldiers will mutiny. ]

[When he heard that food was about to arrive, Emperor Dezong of Tang hugged the crown prince and cried: "The rice has arrived in Shaanxi. My father and I can survive."]

[In addition, in terms of national defense of the capital, the peak Tang Dynasty had its capital in Chang'an, which was naturally conducive to deploying troops and expanding into the Western Regions and Tubo.]

【But Chang'an was often also a base for resisting invasions from the west. 】

【It’s good to be able to defeat him. 】

[If you can’t win, then…]

[After the An-Shi Rebellion, Tubo repeatedly broke through the Dazhen Pass, and the emperor could see the beacon fire from the Hanyuan Hall. Eventually, the emperor of the Tang Dynasty frequently fled Chang'an.]

【With the fall of the Tang Dynasty, Chang'an also bid farewell to its status as the capital. 】

Outside the sky.

Ying Zheng stared at Chang'an's three-dimensional defense system in the sky.

"How strong is Hangu Pass? My Hangu Pass was much more magnificent than the one in this video!"

Ying Zheng also noticed the ecological collapse, and his face darkened: "Did the bamboo forest in Guanzhong disappear first?"

"After my development, this rich and fertile Guanzhong area has been destroyed by future generations?"

"Guanzhong is the foundation of the Qin Dynasty's eternal success!"

“We can’t allow the ecosystem to collapse!”

"Tomorrow, we will mobilize 30,000 prisoners to plant trees on both sides of the Wei River to protect Guanzhong!"

"As long as Guanzhong still exists, the Qin people will never be slaves!"

Tang Dynasty.

Li Shimin felt complicated when he saw this.

It's not just the decline of Chang'an that makes me feel sad.

It was not just to see the Emperor of the Tang Dynasty escape.

I feel sad about the fall of the Tang Dynasty.

"I didn't expect that Chang'an, with the decline of the Tang Dynasty, would no longer be the capital city?"

"Who would have thought of this?"

"Is it true that Chang'an has really declined so completely that all subsequent dynasties no longer use Chang'an as their capital?"

"Tell Yan Lide! Tomorrow we will start planting pine and cypress trees along the Qinling Mountains. For every ten trees cut down, we must plant a hundred!" (End of this chapter)
