檀子 / Tan Zi
檀子 / Tan Zi appears in 《资治通鉴·周纪》15丨酒不醇引发的世界大战 as one of the officials 齐威王 names when 魏惠王 asks whether 齐国 has treasures. The source does not give a full biography; it uses Tan Zi as evidence that useful officials are more valuable than luminous pearls.
In the episode’s reading, Tan Zi belongs to 以贤臣为宝 because his value is measured by border security, public order, and state attraction rather than rarity or display. The page is therefore source-scoped: Tan Zi is preserved as a named personnel example inside Qi Wei Wang’s governance rhetoric.
