The Imperial Family

"Jing-Jing, how much do you know about the imperial family?" asked He Tianhong.

"Not a lot," said Wang Jingyuan. "I know that the crown prince and the fourth prince are full siblings. There's also a Second Prince and Moxian, the fifth prince. Aside from that, I don't know anything else."

He Tianhong nodded. "Alright. So the Emperor has a total of six children, four princes and two princesses. The eldest is Second Prince Xiao Feiqian, borne by Consort Shu. Then—"

"Wait, wait, wait. How come the eldest child is the second prince? Is there not a first prince or princess?" asked Wang Jingyuan.

"There used to be a First Prince, borne by the Empress, but he died young," explained He Tianhong. "There is also Elder Princess Xiao Rou, borne by the Empress as well, but Second Prince is the eldest imperial child by age. He is only a few months older than the elder princess."

"Ohh, I see. Alright, go on."
