The Siege of Yongqiu was a siege for Yongqiu in 756 AD during the An Shi Rebellion, by the An Lushan rebels against the Tang army. The Tang army, led by Zhang Xun, finally won this battle.
Zhang Xun was a general of the Chinese Tang Dynasty. He was known for defending Yongqiu and Suiyang during the An Shi Rebellion against the rebel armies of Yan, and thus, his supporters asserted, he blocked Yan forces from attacking and capturing the fertile Tang territory south of the Huai River. However, he was severely criticized by some contemporaries and some later historians as lacking humanity due to his encouragement of cannibalism during the Battle of Suiyang. Other historians praised him for his great faithfulness to Tang.
An Qingxu (安慶緒), né An Renzhi (安仁執), was a son of An Lushan, a general of the Chinese Tang Dynasty who rebelled and took the imperial title of his own state of Yan. An Qingxu served as the Prince of Jin in 756–757, and later killed his father and took the imperial title for himself. He was eventually defeated by Tang forces and cornered at Yecheng. After An Lushan's general Shi Siming lifted the siege, An Qingxu met Shi to thank him, but Shi arrested and executed him.
