ok, looked at my notes, and it appears they are different people. this article has a pretty good list of Pang Bo employees and their job titles:

So it's:

Zhang Guoqiang, Vice President of Operations of Pangbo Group
Zhang Chongjie, CEO of Education of Pangbo Group

Makes sense they have the CEO of education in charge of the trainings.
