Sichuan is a big basin. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

Lizhou Road, Fuzhou Road, Changzhou Road and Chengdu Fu Road all belong to the scope of the Sichuan Basin, especially Fuzhou Road and Chengdu Fu Road are the center of the basin.

What is a basin? The basin is high on all sides and low in the middle.

It is south to Jiazhou, Rongzhou, Luzhou, west to Yazhou, which is called Lizhou and Mianzhou, and the east is Changzhou.

There are alpine mountains everywhere around here, the mountains are endless, the whole Sichuan Basin surrounds, the road is extremely difficult, especially the west and southwest mountains are even more precipitous, the more you go there, the higher the altitude, especially in the range of Tubo, the altitude is more than 3000. If people who are not accustomed to living on the plateau will have altitude sickness on the Tibetan side, including headache, dizziness, nausea and vomiting, palpitation and shortness of breath, chest tightness and chest pain, insomnia, drowsiness, loss of appetite, abdominal distention, numbness of hands and feet, etc.

Compared with Tibet, Dali is much better.

Although it is also a forest of mountains, there are high mountains and mountains everywhere, but the altitude here is not high, the average is only about 1,000, and the mountains are not as dense as those in Tibet.

Li Chu's army rushed to Yazhou first, and rested in Yazhou for two or three days.

This Yazhou still belongs to the southwest border of the Great Song Dynasty, and borders Tibet to the west.

The 120,000 Qilin army appeared here, and the Tubo side would not be unaware, so Li Chu also specially asked the army to stay in Yazhou for a few more days, specifically for the people in Tubo, so that Tubo could see the Great Song army assembled.

In addition to being stationed in Yazhou, Li Chu pulled the army back and forth on the border to rehearse when he had nothing to do, and such a large formation was enough to shake the Tibetan side.

What Li Chu wanted was the Tubo Earthquake.

Du Niang Encyclopedia is a good thing.

Although the Du Niang Encyclopedia service provided by the customized system can only query some encyclopedias of history or characters, this can provide Li Chu with enough information.

Tibet is a powerful country.

When it was the strongest, it was a super overlord in the Western Regions, and it was able to shake the overlord of the Tang Dynasty, but unfortunately at this time the Tang Dynasty had gone into decline, during the Anshi Rebellion, Tang Xuanzong fled from Chang'an to Sichuan, because the Tang Dynasty dispatched a large number of troops to deal with Tubo to quell the chaos, making the western defense empty, and the Tubo took advantage of the situation to occupy Longyou, a large area of the Tang Dynasty in Hexi. The territory of the Tubo Dynasty was greatly expanded, and the east and the Tang Dynasty were roughly bounded by Longshan, north to Helan Mountain in Ningxia, and in the south, the predecessor of the Dali State, the Nanzhao State, as a vassal state.

Later, the Tibetans occupied Beiting and Anxi, and once advanced to the north bank of the Ganges River south of the Himalayas.

Half of the later generations of China were almost west of Xianyang, and the entire western part was the territory of Tibet, including Dali, Kashmir and other Middle East regions.

It's a pity that the strength of Tibet is like a balloon that has been blown up, and the bigger it blows, the more it will be dispersed once it collapses.

After all, it is a country in the Western Regions, and the population here is limited after all, coupled with continuous expansion, frequent wars have weakened the national strength of Tubo, and after Tubo swelled, it fought several wars with the Tang Dynasty, and was hit hard by the Tang Dynasty's generals Li Sheng, Wei Gao, Shi Jingfeng, etc. many times.

At this time, Tibet was no longer able to expand to the outside world.

And in the country, the local Bon religion and the Buddhism from India had a fight, involving the internal political struggle, and then the Tubo royal family fought for power and seized the throne with each other, so that Tubo fell into division, so there was a scuffle between the Tubo generals, this is not over, the original Buddha Bon dispute has made the people in the country miserable, the warlords and generals fought against each other, and the people were not alive, so the uprising and war broke out.

First, Zhang Yichao, a native of Shazhou, launched an uprising, and the Tang people responded and soon occupied Shazhou. Zhang Yichao also sent troops to capture ten prefectures, including Gua, Yi, Xi, Gansu, Su, Lan, Shan, He, Min, and Kuo (the above areas are in present-day Gansu, Xinjiang, and Qinghai), and finally Zhang Yichao surrendered to Tang.

This is not over, there is an uprising here, and the domestic struggle in Tibet is still endless, not only does not care about this side, but the fight is even more intensified.

The Tibetan royal family was divided into two branches and fought for many years. The Tibetan generals in various places also supported the army and competed with each other.

At this time, the country was in complete chaos, the generals became princes, and some tribes belonging to Tibet in the past also broke away from the jurisdiction of Tibet, which made the already turbulent Tibet even more chaotic.

Before it could end there, an even bigger uprising broke out.

It was a great uprising of slaves and commoners that swept across Tibet, and the Tibetan Dynasty collapsed in this situation......

Crashed......

After that, Tubo has completely become a situation of division of princes.

Whoever does not obey anyone!

Although Tibet is still nominally the state of Tibet, there is no real king to speak in the country, but some princes and kings control it.

And the Tang Dynasty has also weakened, and the Tang Dynasty is gone......

The Central Plains has entered the strife of five dynasties and ten countries, and the country is also in turmoil, and no one has time to take care of the Tibetan side, coupled with the natural altitude sickness of Tubo and the news blockage on the Tibetan side, the Central Plains is not clear about the specific situation on the Tibetan side.

Moreover, although there was civil strife on the Tibetan side and several princes controlled Tibet, these princes and royal families were relatively low-key.

Yes, very low-key.

He kept a low profile and only operated within his own borders, never sent troops to attack other countries outside, and began to regard himself as a transparent person.

In this way, these princes and kings have spent more than a hundred years with the chaotic Tubo, and the Central Plains is already the leader of the Great Song Dynasty, and the Song Dynasty controls the world.

However, although the Great Song Dynasty controlled the Central Plains, but because the sixteen states of Yanyun were occupied by the Liao, they were always attacked by the Liao, and the center of gravity of the Northern Song Dynasty's national defense was in the north.

However, although the focus of national defense is on the Liao, it is not too lax in Tibet.

It has close ties with the Tibetan princes in Gansu, Qing, Sichuan, Yunnan and other places near the Central Plains of the Han nationality. And the princes who control this area are also yearning for the Great Song Dynasty, and have sent envoys to the Song Dynasty emperor many times to pay tribute, and beg for official positions.

Since then, the children and grandchildren of the Tubo princes in this area have all held official positions in the Great Song Dynasty.

And in the end, it was directly incorporated into the Great Song Dynasty.

This area is now Qinfeng Road in the 26th Road of the Great Song Dynasty!

Qin Fenglu, that's how it came!

During this period, the Nanzhao Kingdom was also in turmoil because of the national turmoil, and was finally built by the Duan family, and finally unified the Nanzhao Kingdom and established the Dali Kingdom.

PS: This chapter may have more popular science knowledge, but after all, it is a historical novel, and some of the background must be explained, so that everyone knows, because the current plot is mainly based on the southwest.
