Well, I also took my children to the experience class of Bojia robot. My child is a bit headstrong and insists on seeing me. I stood outside and watched a class. I found that the teacher was really patient and guided the children to think positively. I didn't see the teacher build it myself. It really feels good. I signed up my child, took part in the course for a period of time, and felt the child through the teacher's constant feedback and my own observation.
