Gu Chengyu's "Thanksgiving Letter" made Zhang Hai very displeased; he had long determined in his heart that Gu Chengyu was someone who liked to curry favor and flatter. Thus, towards a few people, he didn't show a good face.
"Since you are now officials of the Hanlin Academy, you should naturally act diligently in your future duties. Do not engage in any deceitful or cunning acts. Otherwise, if discovered by me, there will be severe punishment."
Gu Chengyu understood the implication of these words. Was this being said about him? He had long known Zhang Hai would frown upon his "Thanksgiving Letter". However, he wasn't worried; after all, time will reveal a horse's strength, and time will reveal a man's heart. In the future, being diligent and performing well would suffice.
