When Feng died, Emperor Taizong had not known that Feng was in fact associating with both him and Li Jiancheng, but as he reviewed imperial archives several years later, he began to realize this. In 643, with Feng's involvement in both camps becoming clear, the official Tang Lin (唐臨) submitted a posthumous indictment, requesting that Feng's honors be posthumously stripped. Emperor Taizong accepted the advice of another official, Tang Jian (唐儉), who pointed out that Feng had contributions while he was alive and that the offices should not be stripped but suggested that the posthumous honors be stripped. However, he also changed Feng's posthumous name from Ming to Miao (繆, meaning "inconsistent").
