Also known as Nian Geng. Yue Ke of the Song Dynasty wrote in "History of the Emperor Da Han": "He who was in Japan again passed by with a hat and a fan, so he invited the envoy to talk about Gengjia and asked about the time when he would get his salary."

Song Hongmai's "Rong Zhai Essays: Shi Nian Guan Nian": "When the Duke appointed his son, he wanted him to be an official as early as possible, or he was still a child, so he promoted Gengjia who was several years old." Yuan Yang Hongdao's "Tooth Shake" Poem: "When the teeth are shaken, the eyes begin to darken, and when Gengjia arrives, he knows what is wrong."
