I took part in their group training last year. I did some group activities and group therapy before, and found that I lacked something very rational and very framework. Always rely on feelings, and you will be confused when you walk. After attending the group counseling course in Boren, Shi Jing, I thoroughly found out the reason, and some theoretical foundations told by the teacher were really helpful to us. Maybe we were doing it ourselves before, but we don't know what it is. Now it is clear that the most important thing is to solve a problem about team and group principles, which I think is very helpful. Moreover, in the whole learning process, including theoretical learning, the most important thing is practice, and we will always do it in a group way, which is very helpful to consolidate the learning effect.
