Why complain about the frost on the willows and the Qiang flute? Is it the same? What is the connection?

There is indeed the same effect. Why does Qiangdi complain about willow frosting? Both are famous sentences in frontier fortress poems.

1. The Fisherman's Pride (Qiu Si) by Fan Zhongyan is from Guan Qiang's Long Frost.

Qiang pipe: Qiang flute. A Qiang musical instrument. The flute of Qiang people is melodious, and first frost is everywhere.

2. Why does Qiangdi complain that Liu Yang speaks Wang Zhihuan's Liangzhou Ci?

The poet explained in an open-minded tone: Why does Qiangdi always play the sad tune of "breaking the willow"?

These two poems convey their feelings through the bitterness of Qiang flute with frontier fortress characteristics, which can be described as "the same strain"

At the same time, the former sentence is a scene without me, expressing the deep sadness of frontier fortress life, while the latter sentence is written from a relatively open-minded angle with the opposite argument, showing frontier fortress's high fighting spirit and bold feelings of not fearing life and death. An image of Qiangdi conveys different feelings, but they can all do their best and are really the same.
