There are thousands of words in the history of poetry. In autumn, Mr. Hu's bones were broken, and the thatched cottage was three or five miles away. The spring is beating the old heart.

It's about Du Fu. It's a couplet inscribed by Liu Xianying on Du Fu Caotang in Huanhuaxi, Chengdu, Sichuan. Du Fu is called "the history of poetry", and the thatched cottage refers to Du Fu's thatched cottage in Chengdu. Du Fu's name is Shaoling Yelao, and he calls himself Yelao in Yelao. Du Fu also used "flying around, what am I, but sandpiper in the vast, vast world!" Describing himself in his poems means a flock of seagulls.
