In 1126, the first year of Jingkang, the capital of the Northern Song Dynasty, Bianjing, was captured by the Jin Dynasty. The people were mourned everywhere, and the imperial family of the Northern Song Dynasty was exhausted. Three thousand beauties from the harem and three thousand young beauties from the common people were all escorted into Huanyiyuan and turned into military prostitutes for the entertainment of the Jin people. The condition was tragic, including more than 20 emperor concubines, that is, princesses. The true way is: in the past life, the stars held the moon in front of me, but once I became a prostitute in a foreign land.
