Biedongdaer's poems

Tang dynasty: Gao Shi

Like a bird, she still flapped her wings and felt sorry for herself, leaving Beijing for more than ten years.

A gentleman is poor, who wants to meet today without paying for drinks?

Huang Yun covers the sky and stretches for thousands of miles. The sun is dim. The howling north wind has just sent away the geese and brought heavy snow. Don't worry about having no friends ahead. Who in the world doesn't know you?

When the poet is about to break up, he doesn't write countless thoughts of parting at all, but encourages his friends to embark on a journey and meet the future with passion.

Creative background:

This farewell poem was written in 747 AD (the sixth year of Tianbao in Emperor Xuanzong of the Tang Dynasty), and the farewell object was the famous pianist Dong. In the spring of that year, the official of the official department, Shangshu Fangguan, was demoted to the DPRK, and the door boy Dong also left Chang 'an. During the prosperous Tang Dynasty, Hu music was popular, and few people could enjoy such ancient music as the lyre.

At this time, Gao Shi was also very frustrated, often wandering around and in a bad situation. In the winter of the sixth year of Tianbao, Gao Shi and Dong met in Suiyang (so the address is now in the south of Shangqiu County, Henan Province) and wrote "Two Poems of Biedong University". This poem is his first.
