1. How did Xinjiang develop after the unification of the Western Regions in the Han Dynasty?

With the victory of the war, Central Plains businessmen followed the blood of soldiers and entered the Tarim Basin and Central Asian countries. At that time, we could see that generals, commanders, knights, field soldiers and businessmen were all in droves on the Northwest International Avenue. They set out from Chang 'an, took China's silk products and other handicraft products, passed through Jincheng, Wuwei, Zhangye and Jiuquan to Dunhuang, and then went out of Yumen in the west, crossed the Lop Nur desert, and traded in the countries of Tarim Basin. Even crossed the Pamirs and went to Central Asia to trade with merchants in Rome and India. At the same time, the generals living in the frontier and countless envoys going abroad are also doing business and making a fortune. In this way, Chang 'an is not only the capital of the Western Han Dynasty, but also the center of international trade. This is the place where the national tax revenue is concentrated, and it is also the place where huge commercial profits meet. So in Chang 'an, in addition to the original nobles and bureaucratic landlords, it was crowded with Chinese and foreign businessmen.
