In this learning summary that I do not want to write too much about dance skill and knowledge. However, what is dance knowledge? Is it disjointed between life and dance? This reflection is written after the courses and travel, because the problem of this moment is the most direct and the freshest. I gradually found those specific questions in doubt, my problem is large and empty If I do not know the purpose of problems. Actually some ideas were collapsed in my mind,because there is not enough information and knowledge to support. After this trip, I picked up three points from a lot of interesting ideas to reflect and discuss.
