What image did Moss express?

Loneliness. The door gently covered the sunset and shone on the poet through the crack of the door. The fallen flowers from the trees beside the pond fell on the moss beside the pond.

Ouyang Xiu's ci is colorful and dense in images, but it is handled smoothly and never suffers from stagnation. It can be said that it is a combination of Huajian Ci and Southern Tang Ci. The exquisiteness and novelty of words and expressions is also an obvious advantage.
