—————————— stands autumnal in the evening

after rain the empty mountain, stands autumnal in the evening.

This sentence can also be translated into vernacular Chinese: the empty mountains have been bathed in a new rain, and the night arrival makes people feel that it is early autumn.

It's from an autumn evening in the mountains written by the Tang Dynasty poet Wang Wei.

the whole poem is:

after rain the empty mountain, stands autumnal in the evening. The bright moon sprinkled the clear light from the gap, clearing the fountain on the rocks.

bamboos whisper of washer-girls bound home, lotus-leaves yield before a fisher-boat. The spring of spring may wish to let it rest, in autumn the hills of the sun can stay long.
