"Huang Ming Ancestor Instructions" says: The eldest son of the crown prince is the grandson of the emperor, and the second legitimate son and concubine are all granted the title of county king at the age of ten, and are awarded gold and silver books and silver seals. The women were all given the title of princess and given imperial edicts.
In terms of direct descendants, I am the son of the late crown prince and his concubine; in terms of eldest son, I am the eldest brother of the living grandson of the emperor. I occupy all the direct eldest sons, why can't I deserve the position of the emperor's grandson?
