the Masters of Writing. Meanwhile, Li Bohu was executed for his betrayal against Jin. Despite Fu Jian's flattery, Zhu Xu was determined to return to Jin. He fled to his hometown in Yiyang, where he hid in the home of his friend Xia Kui (夏揆). However, Fu Jian became suspicious of Xia Kui and arrested him, so Zhu Xu decided to give himself up to Fu Hui (苻晖). This only made Fu Jian further admire Zhu Xu for his integrity, and Zhu was appointed as a Master of Writing. Battle of Fei River In 383, Zhu Xu accompanied Fu Jian in his campaign to conquer Jin once and for all. Fu Jian led a massive army to face the Jin forces at Fei River, which were commanded by Xie Xuan. With an overwhelming number on his side, Fu Jian sent Zhu Xu to intimidate Jin into surrendering. However, Zhu Xu instead leaked information about the Qin army to Jin general, Xie Shi, saying, "If all the millions of Qin soldiers were to assemble, it would be difficult for us to defeat them. As of now, their troops have yet to gather, so it is best that we attack quickly. Once their vanguard is defeated, their morale will surely plummet. Only then can we rout them." Zhu Xu later returned to Fu Jian, who had not known what Zhu had done. As the battle was about to begin, Xie Xuan told Fu Jian to move his army slightly back away from the river to allow the Jin troops to cross. Fu Jian agreed, so his brother Fu Rong commanded the Qin army to move back. As soon as they moved, Zhu Xu, who was serving in the rear, shouted, "The Qin army has been defeated!" Many of the Qin soldiers were conscripts who were not willing to fight, so upon hearing Zhu Xu's order, they began to panic and flee from the battlefield disorderly. Xie Xuan quickly crossed the river and attacked the Qin forces, decisively routing them. Fu Rong was killed in battle while Fu Jian barely escaped, but his northern empire would soon crumble because of this defeat. As for Zhu Xu, he managed to escape back to Jin together with another Jin general Zhou Xiao and the abdicated ruler of Former Liang, Zhang Tianxi.
