Poetry appreciation, what kind of feelings are expressed in Liu Zaoqing and Xin Qiji's next film?

The word "now" keeps the tone with the continuation of the last film. Bai Niao laughed at him and said, Now you are finally back, but are you back because of your elegance and "water shield"? The implication is that you had to come back because the official couldn't do it anymore and was fired by others. Such self-exposure not only expresses the poet's indignation at being dismissed from office for no reason, but also expresses his self-mockery and shame at his choice.
