"Director Liu mentioned you to me more than once when we chatted. He had promised to take you as his apprentice and teach you personally. Unfortunately, when several major departments were selecting candidates for the general practice residency, you were chosen by the Emergency Department. You are aware of the fierce competition between departments and the intertwined interests. Old Liu is just at the Deputy Director level, occupying a neither here nor there position, and he didn't have the power to transfer you from the Emergency Department."
Director Jia seems to have a very good personal relationship with Old Liu.
Otherwise, the two wouldn't have discussed such topics.
Old Liu's status in the General Surgery is fine, but within the entire Tuya Hospital, he might not rank very high.
Nowadays, doctors without academic contributions, even those with abundant clinical experience, usually don't hold very high positions.
