Feature 1: Immerse yourself in it. Find a way to let the trainer really focus on the practice, without distraction, and concentrate on the practice.
Feature 2: Skill splitting. Breaking down complex skills into relatively simple modules makes it easier for people to master them.
Feature 3: Safe trial and error. Allow people to experience experiential learning and reflection by making mistakes in a risk-free and safe environment.
Feature 4: Guidance feedback. In the process of people's practice, the coach needs to give everyone the correct feedback in time.
