Ending reminds me of... (spoilers)
So at the end when Po redirect the cannon ball into different direction using his Chi, that scene reminds me of Shaolin Soccer's ending where the goalie redirect the soccer ball back.
And then at the end, Po tries to persuade Lord Shen to become a better person but then Shen turns on Po with a hidden dagger has almost same ending as the Kung Fu Hustle when Sing was fighting the Beast. All three are fun movies to watch. Anyone see similar scene from other Kung Fu movies?
