Last winter, my uncle came to my father and told me that my grandfather had told me about a child marriage early on. That family was my grandfather's good friend in the military. In the beginning, he was just an unknown soldier. Later, he followed the King of Wu, who is now the emperor, and made great military exploits. Finally, he was named the Marquis of Yongchang, and his title was hereditary. The person I want to marry is the son of Marquis Yongchang.
