What does this poem about pine, plum, bamboo and chrysanthemum mean?

Pine, plum, bamboo and chrysanthemum are noble and clean.

Loose,

The proud snow drifted into space with the wind.

Strong waist,

The bones are hard and calm.

In may,

Keywords sexual escape, loneliness, self-indulgence,

Red thousand points,

Fragrant diarrhea in the snow.

Bamboo,

Originally, I had no intention of joining the WTO.

Gao Jie is,

It's good to die

Chrysanthemum,

Autumn is late, so let it be.

The flowers are still in full bloom,

The air in the Imperial Capital is fresh.
