In the Ming Jiajing earthquake, 101 counties were destroyed, and about 280 thousand square kilometers of houses, official offices, temples and academies were reduced to ruins in Shaanxi, Gansu, Ningxia, Jin and Henan provinces. It can be seen that the traditional buildings collapsed in the earthquake.
"The history of ancient Chinese architecture" believes that the wooden frame structure of the ancient Chinese architecture has the characteristics of wood, and the arch of the frame and the mortise and tenon have several expansion spaces, so that the damage caused by the earthquake can be reduced to a certain limit. In fact, the more sophisticated tenon and mortise, the more damage to the original mechanical properties of wood, the connection parts of these components are often the key parts of the force. In fact, the "movability" of mortise and tenon structure is just a kind of helplessness that the ancients did not pass because of the quality of building materials. This can also be proved from the production of ancient furniture: the furniture of Ming and Qing Dynasties is made of hard wood with hard material, because the hard wood and the stick of the fish swim bladder can ensure that the mortise and tenon of the furniture is connected firmly and not.
As a result, it is not the antiquity of the existing ancient architectural structure, but its building material is far superior to those ancient and modern buildings that collapsed in the past dynasties.
