Texas is a state dominated by plains, and its western part is the Cordillera Mountains, where the Cordillera Mountains make a bend to make this a valley, and here it becomes a relatively independent unit, and the mountains bend to the north to form New Mexico and Colorado, which are connected to the original "Lone Star Republic". Here are the major oil fields, with Texas and neighboring Louisiana producing nearly half as much oil as the United States.
In the picture above, the place where the sea enters is a city, which is formed by the arc.
The influence of mountains and rivers on Texas is almost equivalent to the influence of Taihang Mountain on Zhongshan, Taihang Mountain bends on the west side of Shijiazhuang, making it a valley, and it becomes a relatively independent unit, which is the Zhongshan State, which in the Spring and Autumn Period neither belongs to the Yan State nor to the Jin State, whether it is political or cultural, they are relatively independent, and the Zhou royal family does not think that they belong to the Huaxia people. Of course, this is also a large oil field - part of the North China oil field.

For a long time, it was an inland province, the southern part of Guangxi near the seaside, for a long time under the jurisdiction of the coastal province of Guangdong Province, although now this part belongs to Jiangxi, but Guangxi Laobiao is still used to arrive in Guangzhou through the Xijiang River, and then go to sea;
