Traveling westward from Jiayuguan, through Yangguan, you enter the territory of the Ancient Western Regions, hence the famous line: "I urge you to have one more cup of wine, for once you leave Yangguan, there will be no old friends."
However, in Great Chu, due to the golden leg of those who traversed before, the countries of the Western Regions recognize the status of Great Chu as the "Sovereign State," implementing a "one country, two systems" policy and enjoying preferential policies for "ethnic minorities." Han people, along with military households, have migrated here in large numbers, creating a "Great Fusion of Hundred Tribes."
Inside the border, apart from enjoying the conveniences brought by those who traversed before, Susu did not directly feel the strength of Great Chu. After all, even though she was poor in her previous life, she had witnessed prosperous eras.
