More than two thousand years ago, the original princess of the Wusun Kingdom in the Western Regions who was married to the Han Dynasty died, and the old king asked the Han Kingdom to remarry the princess. Emperor Wu of the Han Dynasty selected Princess Liu Jieyou of the Chu Kingdom to go to the Western Regions to make a marriage alliance. After learning about the situation, the Huns were afraid that the Wusun Kingdom would defect to the Han Kingdom, so they also selected the princess to marry the Wusun Kingdom, resulting in a series of conflicts, dangers and dramas. This is a true story about the earliest relationship between the Han Dynasty and the countries in the Western Regions.
