Yinreng is the Crown Prince, Kangxi’s most beloved son. He is handsome and refined, with an orchid‑and‑jade‑tree elegance, and he possesses a calm, observant nature. He happens to meet Sifu leaving Qianqing Palace and is briefly stunned by her beauty, though he quickly hides his reaction. He speaks gently to Sifu and Hong Hui, praising Hong Hui’s character and offering supportive words. He also notices Yinzhen’s neglect and chides him for being an unqualified father. He is positioned as the heir and commands respect, his interactions marked by cultivated grace.
