War poems, poems about frontier fortress and war. The earliest war poem appeared in the Book of Songs, which is an official war poem with gorgeous rhetoric and grand momentum. The pre-Qin period to the Tang Dynasty was the development period of folk war poems, among which frontier fortress poems developed greatly, represented by Gao Shi, Cen Can and Wang Changling. In the foreign wars in Tang Dynasty, many literati participated in them, had personal experience of frontier fortress and military life, obeyed the army instead of writing, wrote poems to describe the desolate frontier fortress scenery, praised the brave spirit of soldiers, or cursed the disasters brought about by the war, so frontier fortress poets came into being. The Journey to the West, a famous poet in Cen Can, is very representative.
