“安史之乱”期间，杜甫历尽艰危，他也用诗笔真实地反映了战乱的过程，其中对参战“胡族”的记述十分突出。当时唐朝与西北、北方、东北的“胡族”通过战争这种特殊的方式进行了一场大交流。胡汉文化的交汇在本来就是胡汉杂居的边地显得越发鲜明，而吐蕃、回纥等地则出现了“一半胡风似汉家”的风貌。 During the “An-shih chaos”, Du Fu experienced the most difficult times. He also used poems and pens to truly reflect the process of the war. Among them, the account of the war on the “Hu clan” was outstanding. At that time, the Tang Dynasty conducted a grand exchange with the “Hu ethnic group” in the northwest, north and northeast through the special mode of war. The confluence of the Hu and Han cultures has become clearer on the sidelines where Hu and Han drew together, while the appearance of “half of the Hu and Han dynasties” appeared in places such as Tubo and Huihu.
