Why couldn't Master Shifu contain Tai Lung, forcing Po to later defeat him in Kung Fu Panda?
Why is it that Master Shifu couldn't contain or defeat Tai Lung, but Po has to fight aganst Lung in order to save Shifu and the Valley of Peace?
It is showed that both Shifu and Po knew Wuxi Finger Hold. So why did Po have to defeat him? He is the student of Shifu anyways. Why is it that the teacher who knew Kung Fu so well, was ultimately unable to defeat Tai Lung? Lung was also a former student of Shifu.
Why was Shifu unable to do what was necessary?
