Yizhou of the Three Kingdoms is not a relatively easy place to defend and attack south

Yizhou is now Sichuan, mainly Xichuan, with Chengdu as the center!!

Because Yizhou is Shu, it is the Sichuan Basin, surrounded by mountains, and in the middle is the Chengdu Plain!!

Since ancient times, there should be a saying that "Shu Road is difficult to walk!!

So Yizhou is an easy place to defend and difficult to attack!!

The following is a brief excerpt of some information, if you are interested, you can take a look:

Geographical location of Sichuan Province.

It is located in the southwest of China, in the upper reaches of the Yangtze River. It occupies the vast majority of the Sichuan Basin. This beautiful and magical basin is controlled by the Qinghai-Tibet Plateau in the west, the Three Gorges of the Yangtze River in the east, the Yunnan-Guizhou Plateau in the south, and the Qinling Bashan Barrier in the north.

The topography of Sichuan Province is high in the west and low in the east, and the west is roughly plateau and mountainous, with an altitude of more than 4,000 meters. The eastern part is a basin and hills, mostly between 1000 and 3000 meters above sea level. The province is divided into two parts: the western Sichuan Plateau and the Sichuan Basin. The Sichuan Basin is one of the four major basins in China, covering an area of 10,000 square kilometers.

Yizhou is surrounded by mountains and plains. Of course, it's easy to defend and hard to attack.

Suffice it to say, it is easier to defend, but it is much more difficult to send troops, after all, the road is rough.

It's an easy place to defend and hard to attack.

Is it difficult to walk the road in Shu, the road is difficult to walk, let alone the march.

Easy to defend and difficult to attack. Whoever scores is attacking and defending.

Yizhou, an ancient Chinese place name, was an administrative division set up in the Western Han Dynasty, and its scope included the area of today's Sichuan Basin and Hanzhong Basin. During the Three Kingdoms period, Liu Bei occupied this place and established the Shu Han regime. At the end of the Three Kingdoms, Cao Wei destroyed Shu Han, divided Yizhou, and placed Liangzhou.

During the Western Jin Dynasty, the Eastern Jin Dynasty and the Northern and Southern Dynasties, it has always been the two states of Yi and Liang. During the period of the Sixteen Kingdoms, the Shu regime was established here.

I won't talk about it before the chaos in the world, Liu Yan, a relative of the Han family, thought that Yizhou had the spirit of the Son of Heaven, so he entered Yizhou, and asked for the state pastoral system, so that the state pastor had military power, and as a result, the state pastor became similar to the vassal states of the Zhou Dynasty.

After Liu Yan's death, his son Liu Zhang took his father's place and became the pastor of Yizhou, and later, for various reasons, Liu Zhang asked Liu Bei to help in Yizhou, and as a result, Liu Bei took the opportunity to take Yizhou.

After Liu Bei's death, his son Liu Chan succeeded him, but it was Zhuge Liang who was in charge, and finally Cao Wei of Shu was destroyed, and then Cao Wei was seized by Jin, and Jin unified the world.

During the Three Kingdoms period, Yizhou included the present-day Sichuan Province, Chongqing Municipality, Yunnan Province, Guizhou City, and most of Hanzhong, northern Burma, Hubei Province, and a small part of Henan Province. Yizhou west to Wudu, Yinping two counties (southern Gansu); north to Hanzhong, Weixing two counties (south of Qinling, Shaanxi); south to Yongchang and Xinggu counties (Yunnan, Myanmar); East to Badong County (Three Gorges, Baidi City area).

Introduction to Yizhou. Yizhou, an ancient place name in China, is one of the thirteen states (Thirteen Thorn History Department) set up by Emperor Wu of the Han Dynasty, and is governed in Chengdu, Shu County. In the fifth year of Yuan Feng (106 years before Brother Xu), Emperor Wu of the Han Dynasty set up 13 departments of history in the country, and the Sichuan region was the Yizhou Department, and the state was governed in Luo County.

In the following hundreds of years, it was successively divided into Shu County, Qianwei County, Zhuti County, Yue County, Ke County, Jianning County, Yongchang County, Hanzhong County, Guanghan County, Zitong County, Ba County, Ba County, Badong County, Yizhou County and other counties in Yizhou, with 146 counties under its jurisdiction, which belonged to the Shu land. It is located in the Hanzhong Basin of present-day Sichuan, Guizhou, Yunnan and Shaanxi.

Yizhou was one of the three largest states at the time, and Liu Bei occupied it and established the Shu Han regime. At the end of the Three Kingdoms, the Western Jin Dynasty destroyed Shu Han, divided Yizhou, and placed Liangzhou.
