In Gao Shi's frontier fortress listening to the flute, the first two sentences of this poem describe when the frontier fortress is in the day.

The first two sentences of the poem describe the frontier fortress scene in the middle of the day, while the first two sentences describe the real scene: the lake is in the north, the ice and snow melt, and it is the time to herd horses. In the evening, the soldiers came back with horses, and the sky shed the brilliance of the bright moon. At the beginning, it creates a quiet and peaceful atmosphere that is rare in frontier fortress poems.

Listen to the flute on the fortress;

Snow-clean horses graze in the daytime, and Qiangdi guards the building in the moonlight.

Excuse me, where did the plum blossom fall? The wind blew all over the mountain overnight.
