《疑孟》 / Yi Meng
《疑孟》 / Yi Meng appears in 《资治通鉴·周纪》26丨孟子来了！ as 司马光’s text questioning 孟子 / Mencius. The episode uses it to complicate the simple idea that Sima Guang’s sympathetic reconciliation of the renyi-benefit passage means he personally admired Mencius.
Its wiki role is source-scoped. The page records that the episode places Yi Meng inside 宋代孟子接受史, where 王安石’s enthusiasm for Mencius and Song reform politics made Mencius’s status intellectually and politically charged.
