The Jin dynasty was ineffective in its attempts to halt the uprising. The Jin capital, Luoyang was open to Liu Yuan's son Liu Cong (who was now commander of the rebellious forces), and he attacked Luoyang twice in 309 and 310, without success. However, the Jin Chancellor Sima Yue fled Luoyang in 310CE with 40,000 troops to Xiangcheng in Henan in an attempt to flee this threat.
