What's the function of the scholar who has been locked up in Chang 'an for the longest day to avenge the horse?

First of all, I think he exists as a witness, because he witnessed some situations of Jing 'an Company from prosperity to decline, so he exists as a witness. Secondly, he also reflected some bad phenomena in the society, and the image of this scholar is also a distinctive image in the tradition, which also witnessed some historical positions of scholars in history.

On the one hand, he exists as a witness, because you have to know that his Jing 'an teacher experienced danger and was supported by the new ruler, so I think he is playing a witness here, and more importantly, a pair of eyes. Moreover, he also has a very important relationship with several important figures in the whole play, and has a little contact with them. Cell seems to have witnessed the rotation of some relationships in the whole drama, so I think his role in this layout is a witness, a medium for relationship transformation, and more importantly, a witness.

On the other hand, I feel very helpless. As a scholar, he was trapped in prison, and his horse was killed by Zhang Xiaojing while chasing gangsters. So I think since he can come to discuss it, it shows that he cares about his private property. It can also be seen that he has a very good relationship with his horse, and it is really hard in prison because there is no food to eat. Every time someone comes in, he will ask others if they have food. And as a classic literati, I think he also represents the position of this level of literati in the government in history.
