Po: [gasp] The Wuxi Finger Hold! Not the Wuxi Finger Hold!
Shifu: Ohhh, you know this hold?
Po: Developed by Master Wuxi in the third dynasty, yes.
Shifu: Ah, then you must know what happens when I flex my pinky...
The Wuxi Finger Hold is an advanced, powerful Kung Fu technique that involves the user holding an opponent's finger between his or her own index finger and thumb, pinky held upright. By flexing one's pinky, the target's chi is presumably affected so greatly that it causes a brilliant, rippling shockwave of energy that extends for miles, though what exactly happens to the target is unclear.
Master Wuxi is credited to have developed this technique during the third dynasty. This hold remains to be the most feared and secretive technique in the entire Valley of Peace, capable of creating maximum amount of damage with just the minimum amount of effort.
After Po was selected as the Dragon Warrior, he was sent to the Hall of Warriors to meet with Master Shifu, who shared with him his disbelief in Po being the Dragon Warrior and insulted him. When Po tried to argue, Shifu threatened to use the Wuxi Finger Hold on him; scared, Po backed down and didn't want to argue with him afterward.
Sometime between this point and his fight with Tai Lung, Po figured out how to use the Wuxi Finger Hold himself and used it against Tai Lung, who gasped in shock and reasoned that Shifu never taught him the hold and tried to call it out as a bluff, but much to his surprise, Po admitted that he actually figured the hold on his own; with a flex of his pinky and saying his catchphrase "Skadoosh," Po defeated Tai Lung.
- In the first Kung Fu Panda storyboard version of the Wuxi Finger Hold, Shifu instead used a Chinese finger trap to catch Po.
- In a Scholastic News Online interview with "Po", when asked about the hardest move for him to learn, Po answered it was the Wuxi Finger Hold and states that Shifu told him (after having defeated Tai Lung with it) that there actually is no such move; it was just a story that masters made up to scare their students. Po added that he can't recall exactly how he did it, but he feels he must practice.
- Though unconfirmed, the move might have been inspired by the "Five-Point Palm Exploding Heart Technique" from the Kill Bill movies.
