There was no direct correspondence. Generally speaking, a professor is equivalent to a deputy hall, a second is equivalent to a main hall, a third is equivalent to a deputy hall, a fourth is equivalent to a central office, an associate professor is equivalent to a deputy hall, a lecturer is equivalent to a division, and a teaching assistant is equivalent to a clerk. Professors can only correspond in a general sense, depending on academic status, senior political contributions and fellow students, rather than direct and practical power.
