Well-known training institutions in Harbin include Zhong Hui, Yuhuan, Art View and Good Quality, each with its own advantages, but the key point in choosing training institutions is to pay attention to the teaching staff. I was successfully promoted to this university last year. At that time, I chose Yijing to be promoted to this university, because their teachers are all in-service university teachers, and 30 students teach in small classes, which is very cost-effective.
