Bachelor of Philosophy In China, the Bachelor of Philosophy is one of the thirteen statutory types of bachelor's degrees. It is awarded to students who have completed an undergraduate program with a major in Philosophy, Critical Thinking, or Religious Studies Bachelor of Philosophy (BPhil, BPh, or PhB; Latin: Baccalaureus Philosophiae or Philosophiae Baccalaureus) is the title of an academic degree in philosophy that usually involves considerable research, either through a thesis or supervised research projects. Unlike many other bachelor's degrees, the BPhil is typically awarded to individuals who have already completed a traditional undergraduate degree. https://en.wikipedia.org/wiki/Bachelor_of_Philosophy
In academia, "philosophy" has two meanings. First, it comes from two Greek words, philein and sophia. Essentially, they combine to mean "lover of learning." The second meaning, of course, is the discipline of philosophy. This is why there is a doctor of philosophy degree in many areas, not just philosophy. But the Chinese version cited by the OP uses the word as the discipline, not the broader "lover of learning."
Moreover, "doctor" originally meant teacher, and yet in most PhD programs you don't learn anything about either teaching or philosophy. It's like the Holy Roman Empire of degree nomenclature.
It's weird. Teaching is a fundamental role in higher education (research and grant-writing are the other two). Yet, as you put it, PhD programs teach neither pedagogy nor andragogy. And when there as an attempt to design a doctorate that did--the Doctor of Arts--the industry beat it to death with a big stick.
No, the two primary foci of Higher Education are 1) supporting a credible football team, and; 2) providing a cushy existence for tenured faculty and an amazingly rewarding career for upper level administrators. Teaching is somewhere around 19th on the list just after golf course maintenance and ahead of student financial counseling.
Snark aside, isn't the B.Ph. one of the traditional first level "graduate" degrees like the B.D., B. Litt., and B.C.L.?
If we're going to go in that direction, I always thought the keys to running a university were football for the alumni, parking for the faculty, and sex for the undergraduates.
