The Emperor's ninth son, sixteen years old, described as the most handsome among his brothers. He was doted on in childhood by his mother Consort Yi but gradually faded from prominence. He couldn't surpass his seventh and eighth brothers in studies, nor match his thirteenth and fourteenth brothers in horsemanship and archery. He developed a keen interest in foreign languages and odd gadgets. Business was his hidden hobby. He was overjoyed when his nephew elevated their venture into a major Mongolia business deal. He stayed up late drafting plans and was ultimately tasked with managing the entire wool trade with official backing.
