Cao Shuang was largely viewed as an incompetent regent who entrusted many of his associates who were equally lacking in ability. In 244, for example, under the advice of Li Sheng and Deng Yang, Cao Shuang, lacking in military talent, nevertheless carried out an attack against Wei's rival state Shu Han, without carefully planning the logistics, and even though the battles were inconclusive, Cao Shuang was eventually forced to withdraw due to large number of deaths of livestock, and during the withdraw, many soldiers died in battle or of other causes. Cao Shuang also gathered great wealth for him and his associates, and also spent much time on tours, away from the important matters of state, since 247.
