李谈 / Li Tan
李谈 / Li Tan, also transmitted as 李同 / Li Tong, enters the wiki through 《资治通鉴·周纪》96丨毛遂自荐（4） during the 邯郸 siege. The episode describes him as a minor Zhao figure connected to lodging or service work, not as a famous court minister.
His importance is the remonstrance to 平原君. Li Tan says the people of Handan have reached the extremity of burning bones and exchanging children for food, while Pingyuanjun’s household still preserves wealth, fine food, clothing, women, servants, and metal goods. He argues that if Zhao falls, Pingyuanjun’s household will lose those privileges anyway, so the only useful choice is to convert private wealth and household labor into city defense.
Pingyuanjun follows the advice: he distributes family wealth, sends wives, concubines, and servants into the army, and recruits three thousand dare-death fighters. Li Tan then joins the fighting himself and dies in battle. Zhao later honors his father as Li Hou, so the episode treats Li Tan as a persuader who also bears the risk he demands from others.
The episode also explains the Li Tan / Li Tong variation through 《史记》 name avoidance. Because 司马迁’s father was Sima Tan, some “Tan” names appear with “Tong” in the received historical text. This makes Li Tan a small but useful case for textual-variant caution: name form alone should not create a separate wiki person without source evidence.
