In a scene early on in the film, Mousy is washing the laundry with his bossy sister. After complaining about the repetitiveness of laundry work, his sister scolds him and demands he wash the clothes in the “family way.” This leads to a scene with Mousy flipping the clothes around with his hands and wringing them out with powerful squeezing from this index finger and middle finger. These abilities turn out to be related to kung-fu methods, as Mousy eventually uses the same laundry method to defeat White Tiger.
