First of all, Yao Ru can hide the scandal. I think the most important reason is that he should consider his own interests, and he should use the scandal to deepen his contribution. Because copywriting was an important role at that time, and he also mastered many important things, he felt that if he could catch the smell, he could go to his boss to receive a reward. Secondly, he hid Wen Ran, considering the relationship between Zhang Xiaojing and Wenran, so he can only do this to avoid Zhang Xiaojing, so that he doesn't know the whereabouts of Wenran and indirectly interrogate Wenran.

On the one hand, he hid Smell and Dye in that place, in order to make himself go more smoothly on the road of promotion in the future and enhance his contribution. Because he caught Smell and Dye by himself, he is a meritorious person, so he can improve his position in officialdom by smelling and dyeing this matter. Moreover, Wenran itself is a more important role in the play, and his ability to catch her indirectly reflects that he has a good role in the play.

On the other hand, it is to avoid suspicion, because Zhang Xiaojing has a very good relationship with Wenran, so if Zhang Xiaojing knows that he has caught Wenran, he will cause a series of dissatisfaction of Zhang Xiaojing, or revenge of Zhang Xiaojing, so he hides Wenran indirectly, which can also reflect one of his wisdom. I think he did a good job in handling this matter. He was able to hide such an important witness and avoid important authorities from asking for important people from himself. Moreover, his hiding place was so hidden that no one found him. I think he did a very good job.
