I actually have a big problem with qi being introduced in this movie. In the animated movie, Mulan was a regular person, like me and you, who took it upon herself to gather the strength and courage to do something extraordinary. That’s the lesson I learned as a kid, « a single grain of rice can tip the scale », which meant me too if I only worked up the courage to. But with qi, which is essentially a superpower, Mulan is already great and powerful and above us, regular folks, and the only obstacle is that she has to « show her true self ». So, in my opinion, the whole lesson of the original movie has been lost :/
