The situation within the pass is not good, and it's hardly better outside the pass. Gaochang was destroyed because they colluded with the Turks, made outrageous statements disrespecting the emperor and the Great Jin, and stopped paying tribute.
This indicates that there is a significant force among the fleeing Turks in the Western Regions.
Furthermore, the countries in the Western Regions were never truly submissive to the Great Jin; they only submitted due to the power of the Great Jin and the emperor. Once unfavorable news about the emperor spreads, these people will rebel.
Regarding this, General Meng bluntly said, "These people are opportunists; when His Majesty is well, they cry poverty and ask for money. The court provides them with money and grain for support, but once His Majesty is not well, a few words of incitement from others will have them all riled up, turning previous deep sentiments into false ones."
