Qu Zijin is the Grand Tutor responsible for teaching the princess and Jin Lanyue. He is a stern and old-fashioned man who started his career as the top scholar of the imperial examinations, basking in boundless glory. However, due to his lack of interpersonal skills, he was repeatedly suppressed and marginalized, eventually reassigned to serve as the princess's tutor. He is depicted as fierce and strict, often scolding the children for being late. Despite his harsh exterior, he harbors a sense of justice and believes in the innocence of Jin Lanyue and the princess. In the system's future storyline, he is sentenced to decapitation after submitting petitions on their behalf, but in the present, he is moved by Jin Lanyue's genuine concern and blessing, leading to a softening of his demeanor. He is a supporting character who may become an ally.
