Abstract: An apparatus for practicing art of attack and defense includes a base, an elastic force regulating set and a cylindrical member. The elastic force regulating set further includes a spring, a hollow cylinder and a Y-shaped hollow post. The hollow cylinder and the Y-shaped hollow post adjustably engage with each other with screw threads and distance between the hollow cylinder and the Y-shaped hollow post is capable of being regulated to create elastic force change for providing a specific elastic force needed by the user. The space in the base can be placed with a solid or injected liquid to offer steady center of gravity against being hit down. Further, the cylindrical member, the hollow cylinder and the Y-shaped hollow can be received in the base conveniently after use.

Abstract: A toilet device includes one or more toilets, and a displayer device disposed above each of the toilets for displaying photo images or video programs or the like, while the users are using the toilets. The displayer device may include a screen for displaying the photo image or the video program from such as the tape or compact disc displayer. A processor unit may receive and send the radio or video signals to the displayer device. A detector may be used to detect the users and to actuate the displayer device and to flush the toilets.
