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.
Pada tahun 244, misalnya, di bawah saran Li Sheng dan Deng Yang, Cao Shuang, yang tidak memiliki bakat militer, namun melakukan serangan terhadap negara saingan Wei, Shu Han, tanpa perencanaan logistik yang matang, dan meskipun pertempuran tidak dapat disimpulkan, Cao Shuang akhirnya dipaksa mundur karena sejumlah besar kematian ternak, dan selama penarikan, banyak tentara tewas dalam pertempuran atau penyebab lainnya.
