Empress Yang's oldest son, Sima Gui (司馬軌), died in childhood, making her second son, Sima Zhong the legitimate heir, by traditional succession laws. However, Emperor Wu hesitated about selecting him as crown prince because he was developmentally disabled. Empress Yang was instrumental in persuading him to have her son designated crown prince anyway, arguing that tradition should not be abandoned easily. She was also instrumental in her son's selection of a wife, as Emperor Wu initially favored Wei Guan's daughter, but Empress Yang, friendly with Jia Chong's wife Lady Yang, praised Jia's daughter Jia Nanfeng greatly, leading to Jia Nanfeng's selection as crown princess.
