The Princes of the Royal Family, at this time, must stand on their own.
If it's the Crown Prince, it's only more exhausting.
Just look at Zhao Junyao.
He was made Crown Prince at ten and ascended to the throne at nineteen.
By the time he was enthroned, there was already a group of women in the harem.
If he was lucky, or if the women in the harem were well-behaved, he likely already had a bunch of children by then.
And upon his enthronement, he had to rule personally, managing the affairs of the whole world.
All decisions had to be made by himself.
He had to match wits with the Imperial Court Officials, controlling the ever-changing political climate.
He had to have a discerning eye to distinguish the loyal ministers from the sycophants.
He had to be brave and resolute; he had to have both courage and strategy.
In short, he had to shoulder the entire kingdom.
So... there wasn't much time for him to grow up.
