Cao Xiu
When Cao Xiu's mother died, Cao Pi issued an imperial decree to exempt Cao Xiu from the formalities and austere lifestyle of filial mourning, which was customary for officeholders when their parent(s) died. He excused Cao Xiu from wearing mourning garments and gave him permission to consume meat and alcohol. However, when Cao Xiu's health deteriorated due to grief and his desire to return home to Qiao County (譙縣; present-day Bozhou, Anhui) to hold a proper funeral for his mother, Cao Pi approved and sent Xue Qiao (薛喬) as his personal representative to offer his condolences to Cao Xiu and attend the funeral. Cao Xiu settled the funeral arrangements and had his mother properly buried within one day, after which he wanted to return to his post. Before Cao Xiu left, Cao Pi met him in person to comfort and console him. This incident showed how close Cao Pi was to Cao Xiu and how highly he regarded Cao Xiu.
