姚萇
Murong Yong, once he settled in Zhangzi, carried out few military campaigns and appeared to be content with his domain. In 387, he did briefly engage Later Qin's emperor Yao Chang in battle, but did not seriously attack Yao. In 390, he headed for the Jin city of Luoyang, but the Jin general Zhu Xu (朱序) defeated him, and he withdrew. He attacked Luoyang again in 391 but was again repelled by Jin forces.
