Introduction to Civil and Military Affairs: In 227 AD, Zhuge Liang went to the Northern Expedition of Cao Wei and passed Ma Chao's tomb. He ordered his younger brother Ma Dai to pay filial piety and visit the tomb to offer sacrifices, inspiring the soldiers of the three armies to turn grief into strength. Liu Bei praised Ma Chao: "He has faith in the Northern Territory, and he is powerful and powerful." Zhuge Liang commented on Ma Chao: "He has both civil and military skills, he is brave and heroic, and he is a great hero in his lifetime."
