Shi Le
In fall 328, Shi Hu attacked Han Zhao's Hedong Commandery (roughly modern Yuncheng, Shanxi). Liu Yao personally led an army and defeated Shi Hu, and then headed south and surrounded Luoyang, capturing several commanderies around it. This greatly shocked Shi Le, as he was worried that Liu Yao would next attack his capital Xiangguo (襄國, in modern Xintai, Hebei). In winter 328, Shi Le personally led a relief force to Luoyang. Meanwhile, during the siege of Luoyang, Liu Yao took no precautious to cut off Chenggao Pass (in modern Zhengzhou, Henan), and Shi was able to pass through it and arrive at Luoyang. In connection with this war by Shi Le against Liu Yao in 328 CE was uttered the only phrase in the Jie language which has survived to modern times, recorded phonetically in the Chinese annals, glossed with a Chinese translation. The phrase has since been analyzed and translated in numerous publications.
