Other than eating, lazing around, scheming, complaining, and scheming some more, he loved reading.
While at the institute, the one place he spent most of his time in, was the main Library. The brief recess time he got when they were not in classes, training, cultivating, or being maliciously beaten by the instructors and some prisoners from the requiem who they often sparred with, he would often spend it at the library.
For a place that was the size of a small town, the volume of knowledge the Main Library contained was astronomical. Yang Qing would choose subjects to read at random very soon it became a habit that he has retained till today as whenever he had time he would still visit the library. He wasn't the only Order employee who did so either.
