Faced with the enemy troops defending outside the city, Zhang Xun and Xu Yuan's troops gradually ran out of food. In order to buy some time for the Tang army, Zhang Xun killed his concubine and let the soldiers eat it. Then, Xu Yuan also killed his family and servants to satisfy the soldiers' hunger. From this aspect, both Zhang Xun and Xu Yuan have a strong spirit of patriotism. They would rather kill their own families to allow the soldiers to have the physical strength to guard Suiyang. Although Zhang Xun and Xu Yuan were civil servants of a generation, their tenacious and unyielding national integrity shocked many people throughout the ages. Zhang Xun and Xu Yuan struggled to defend the city, but were eventually captured by the enemy and entered Suiyang. After the city was broken, Zhang Xun and Xu Yuan were captured by the enemy. They were unwilling to surrender to the enemy and were eventually killed by the enemy. "Wen Di" is a representative poem by Zhang Xun, a famous official of the Tang Dynasty. It was written during the Anshi Rebellion. The poetic work "Wearing the Flute" expresses the poet Zhang Xun's generous and sad spirit of resisting the enemy. First of all, let's appreciate the poem content of "Wearing the Flute": "As soon as the mountains are coming, the captives are riding in the shadow of the city. I don't know the color of wind and dust, how can I know the heart of heaven and earth? The moon is close to the side of the door, and the clouds are deep in the battle formation." I watch the night watch upstairs and hear the sound of the flute in the distance.
