Huang Jingren's life is bumpy, and his poems about the bosom are the most typical. However, it seems that this poem about diseases is not quoted much, and there is not much information found, so the following is just my humble opinion for your reference.

Gull is the image of hermit in poetry, such as gull forgetting machine, heron friend gull couple;

The wild goose is a swan, and the ambition of the swan is to be broad-minded and ambitious. However, the poet added the word "falling" in front, but the geese who should have flown high left the sky, which not only meant seclusion, but also expressed their grief through the word "sorrow" at the end. It can be seen that this seclusion is not what the poet wants, but what he has to do.

So I think these two sentences mainly express the melancholy mood of the poet's unsatisfied talent.

As for the word "equality", the level is limited and it is impossible to know.
