李存勗
Later in 919, there was an incident when Guo opined that Li Cunxu was having too many people attending meals with him, and wanted Li Cunxu to reduce the size of these meal gatherings. Li Cunxu, in anger, told his secretary Feng Dao to draft a declaration stating that he was going to leave the command of his main army to someone else and return to Hedong's capital Taiyuan by himself. Feng, however, defused the situation by persuading Li Cunxu that Guo was not faulty in his suggestion. Guo subsequently apologized, and this matter did not affect their relationship significantly at that time.
