What are the images in Zuo Si's Ode to an Epic and how to express the poet's feelings?

I don't know if this is it. Image: pine trees at the bottom of the stream, seedlings on the mountain, trunks with an inch diameter, and hundreds of feet.

This poem says that "there is no poverty in the top grade and no family in the bottom grade" since the Wei and Jin Dynasties, "Jun Gao is the best in the world." The sharp contrast reflects the contradiction between the poor and the gentry, exposes the decay and darkness of the gate system, and cites historical facts to explain that it is an ancient thing for talents to create oppression. Such poems not only comment on reality, but also on history; What is condemned is no longer an accidental phenomenon, but a chronic disease of society; It not only expresses the author's personal resentment, but also represents the grievances of the poor throughout the ages.

You don't have to write it all down, just extract it.
