The invention provides an antiseismic product, and relates to an antiseismic building. Because 18 times of earthquakes above M7 and 1 to 2 times above M8 occur on the earth each year, people are in dire need of various antiseismic products. The invention provides the building capable of adopting automatic prevention measures to resist earthquakes. The entire building is designed by adopting the principle of tumblers; therefore, the building is just like a tumbler and does not collapse in a new environment when an earthquake causes ground cracks, sinking or land slides.
