Wang Duo is executed in 356 after offending Dong, who had then advised Fu Jiàn that a high level official needed to be executed in accordance with astrological signs.

Because Fu Sheng is blind in one eye and apparently apprehensive that people would be making fun at him or be contemptuous of him due to this disability, he orders that words such as "missing," "lacking," "slanted," "less," and "without" not be used.

He also engages in heavy drinking, and he often either ignores officials' petitions altogether or makes irrational decisions on them in the middle of his stupor, allowing his attendants to make random decisions on his behalf.

For example, Xin Lao is killed in 356 by an arrow Fu Sheng launches during the middle of a feast after Fu Sheng had become displeased that he, as the master of ceremony, was not getting everyone drunk.

Fu Sheng also carries out cruel punishment—in addition to frequent executions, he also likes to cruelly treat animals—including throwing them into boiling water or skinning them alive; the latter punishment he sometimes applies to humans.

When his uncle Qiang Ping, Empress Dowager Qiang's brother, tries to correct his ways in 356, he breaks Qiang Ping's skull by hitting him with a hammer him, then executes him, causing Empress Dowager Qiang to die in sorrow and fear.

Also in 356, Fu Sheng's brother Fu Liu, the Prince of Jin, is able to persuade the Former Liang regent Zhang Guan to have the young Former Liang ruler Zhang Xuanjing become a vassal.
