促膝青螭舫，连觞紫绮裘。

《郎官湖》是一首宋代贺铸的诗词。以下是这首诗词的中文译文、诗意和赏析：

当年贤守令，载酒沔南游。
In the past, as a wise and virtuous official, I traveled to the south of the Mian River, carrying wine.

凉月呈新霁，明湖涵素秋。
The cool moon reveals the clear sky, and the bright lake reflects the pure autumn.

郎官夏口使，仙客夜郎囚。
As a government official, I am sent to Xia Kou, while the immortal traveler is imprisoned in Ye Lang.

促膝青螭舫，连觞紫绮裘。
We sit close together on a green dragon boat, toasting with purple silk robes.

高驩随雨散，余躅想风流。
Our high spirits scatter with the rain, and I am left pondering the elegance and charm.

芳草失青履，沧波浮白鸥。
The fragrant grass has lost its greenness, and the waves carry white seagulls.

江吞百顷尽，石刻一篇留。
The river engulfs hundreds of acres, leaving behind only a stone inscription.

宜有沈碑者，前怀陵谷忧。
It is fitting to have a sunken monument, as it reminds me of the worries in the Linggu Valley.
