Keep the same understanding, not obscure; Words are condescending, but it is difficult to change things. -the meaning of this gentleman's behavior? thank you

This is a poem by Weng Tonghe, the emperor of the two dynasties. Its obvious meaning seems to be very similar to the essence of doing a good job in the literary and art circles: we must have our own opinions, understand the same, and seek common ground while reserving differences; We should not only be able to distinguish subtleties, but also conform to the mainstream, focus on and cooperate with the central work, not be complacent, start from difficulties, open up the work situation and go all out.
