The young prince is the smallest in age and stature in the entire Imperial Academy, making it indeed unsuitable for him to be seated in the second-to-last row.
Nearby, Rong Qijun, undeterred by Gu Lan's mockery, said flamboyantly upon seeing Rong Yunhao wanting to sit beside Gu Lan, "Gu Lan, I'll do you a favor. Qin Zhenghu, go to the back row and sit with Rong Heng, let Yunhao sit over here."
Being the Second Prince, Rong Qijun was different from others in configuration; besides Yuan Lang, he also had a companion study partner, whom he referred to as Qin Zhenghu.
Initially, Gu Lan only felt that the young man beside her looked composed, presumably older than the rest, and realized he was the one who attempted to stop Rong Qijun from getting angry at the young prince a few days ago—unsuccessfully.
Upon hearing the name Qin Zhenghu, she suddenly remembered.
Qin Zhenghu is the Minister of Industry in Yan Country mentioned in the book.
