Zhuge Zhan (simplified: 諸葛瞻, traditional: 諸葛瞻, pinyin: Zhūgě Zhān), courtesy name Siyuan (思遠), was Zhuge Liang’s biological son, born in 227. He was intelligent and well regarded from youth; Liu Shan gave him his daughter in marriage and he inherited the marquisate of Wuxiang (武鄉侯). He rose to General of the Guards (衛將軍) and Director of the Secretariat (錄尚書事). In 263, when Deng Ai led the Wei army through Yinping and approached Chengdu, Zhuge Zhan led troops to resist at Mianzhu (綿竹). He rejected Deng Ai’s offer to surrender and fell in battle; his son Zhuge Shang (諸葛尚) died with him. Liu Shan then surrendered to Deng Ai. Zhuge Zhan was praised for his loyalty; Chen Shou noted that although he was skilled in calligraphy and painting, he could not prevent Huang Hao from wielding power—perhaps implying he lacked his father’s political weight. His other son Zhuge Rong (諸葛京) fled to Wu after Shu’s fall.
