Wu-Wei is another taoist principle shown in the movie. Wu-Wei is the cultivation of the mind, or the flow of life and it falls in directly with peace, as one of the movies main focuses is the discovery of this peacefulness. Along with filial piety and yin and yang, this is also a very important part of taoism. Being the main focus, all of the other principles can be put into this more general category.
I would recommend this experience to a future 8th grader. This experience was not only fun to watch, but it is also full of examples of Chinese culture. I enjoyed the comedy that was applied to this movie and would hope that future students would get to enjoy this as well.
