Liu Yuan relocates after a famine in 305 to Liting (in modern Changzhi, Shanxi).

The various agrarian rebel generals who are resisting Jin rule, whether ethnically Wu Hu or Han, often choose to come under Liu Yuan's Han banner as years pass.

Chief among these are the Han general Wang Mi and the Jie general Shi Le (both of whom had declared loyalty to Han Zhao in 307), who generally only nominally submit to Liu's orders while maintaining separate power structures but who also so appear to genuinely respect and fear Liu.

As for troops under his own control, Liu largely entrusts them to his son Liu Cong the Prince of Chu and his nephew Liu Yao the Prince of Shi'an.

The four generals, while unable to hold cities, are generally able to rove throughout northern and central China unimpeded by Jin forces, defeating most Jin generals who oppose them.

In fall 844, the three eastern prefectures surrender to He Hongjing and Wang Yuankui, and soon thereafter, Liu Zhen is killed by his own officer Guo Yi, who then surrenders.

The slackening of imperial efforts in systematic improvements to the levee system leads to a major change in the course of the Huang Ho during the early years (1850-64) of the Taiping Rebellion in South and central China.

The river returns to its old course north of the Shantung Peninsula in 1852-54, removing Süchow's westward waterway link.

The Nien's activities greatly intensify, partly by the addition to their numbers of a great many starving people who have lost their livelihood from the repeated floods of the Huang Ho in the early 1850s, and partly because they have become emboldened by the Taiping advance north of the Yangtze.
