During the reign of Emperor Xuanzong of the Ming Dynasty, Emperor Xuanzong deposed Empress Hu under the pretense that she had no children, and established a new descendant, the Sun family. After Hu Shanxiang was deposed, she unexpectedly became pregnant and gave birth to a prince and was sent back to the palace to be raised. Hu was disheartened and refused to return to the palace. The son of the Hu family was forced to become a concubine, and the eldest son, the son of Queen Lixin, started a different palace battle for the prince.
